s13 chevy 350

[eazye2000]

if you need any help with block code, or head codes, let me know. I have a list of just about every chevy motor/head ever produced. a few "LTx" ones too. along with the "LT-x" as well as the "Lxx" too

whenever i have any muscle car questions, i just ask my dad the 454 i posted is his

[2LO4URHO]

Tell 'em I'll take it!

[2LO4URHO]

Bingo. LT1s are now very plentiful in junkyards and have a more compact EFI, better ignition (optispark instead of old distributor), better cooling, and make more power than the TPI engines before that (which were a massive jump up from the throttle body, which was at best a stop-gap until true EFI came out). If you go LT1, just remember the cooling is better because it uses a reverse flow, so make sure you have the right water pump!

dougroost -Thankyou appreciate any info I can get.

eazye2000 - I'ma take you up on that offer my friend.

ourmartyr- you got any updates brewing back there?

[White Comet]

Tell 'em I'll take it!

hahahahah, good like putting a big block in an s13's engine bay

[2LO4URHO]

hey like they say, there's always room for improvement lol

[White Comet]

yeah but theres not enough room for improvement in the engine bay

[eazye2000]

Only thing I don't like about using an older small block chevy motor in a swap, is the distributor in the back. Especially if you're using HEI ignition.I would much rather have the newer LS aluminum block. Not to mention the ECU's can have stuff DELETED in them! Like the gas tank pressure sensor..(cap off) Rear O2 sensor. blah blah.Lots of other stuff, but I'm tired. bleh

That's why I recommended LT1, the OptiSpark setup is on the front of the engine so no bid distrbutor in rear. There's no doubt the LS1 is better in every way, it's just going to be harder to find in a junkyard and cost quite a bit more.

i drive a 89 as a daily and just bought a 90 for my beast. I am planning on dropping a 400 chev small block into the 90. high compression pistons, the whole 9 yards you know. then i came across gold. I went to a swap meet, and picked myself up a frickin TURBO for a chev 350, never heard of em except for the super muscle cars, well long story short, i think this car is going to beat anything that comes up on the red light. So this would be called what in the terms of nissan? C400KT? (Chev 400 Carbed Turbo'ed) lol.

I see, so you're saying go all carburated or all fuel injected, throttle body is the worst one?

To swap throttle body for carbed.... swap the intake manifold, and swap the fuel pump. By the way, EFI would not work. Unless you can wire up the chev computer to make it work right.

Just a little heads up, I did a sbc 350 swap about three years ago in one of my s13 coupes, a few things youll need to do

1. you need to chance the fuel pump to a low pressure if you are using a carb, i used a dip tube in the tank and an inline pump, worked great.

2. youll need to clearance the firewall, a lot. gm transmissions have really large bellhousings, and for the engine to sit far enough back, itll need to be cut.

3. do research on gear ratios. most old gm transmissions (th 350 and 400 is all i would use, i used a th350) are non overdrive. meaning that youll be doing a whopping 95mph at 6500rpm in third gear with the 240'd stock 4.08 gears. Look into something with overdrive or a taller gear (iirc turbo z32's and q45's have a 3.50 ish gear) i would reccomend to anyone doing this swap to go for a 5 speed manual, from a gm pickup or the like. Most old gms use the same bellhousing from engine to engine.

Good luck on the project!

Oh and i dont have a lot of pics but if i can find some of any value ill post them up, im not much of a picture taker.

dude, thats not a big deal. ive seen plenty of v-8's with single and twin turbo's. there not stupid fast until you get to that 88mm and up range

[hotrod240sx]

no need to worry about crossmember mods with the old school v8 i have been looking into this swap already, i love the 350's and all v8 chevys. mckinny motorsports already has a custom oil pan and pickup to work with the factory crossmember and also the motor and transmission mounts to work with the motor and either turbo350 trans, or t56 manual trans. and i can tell ya from experiance the trans turbo 350 trans mount setup should also work with a 700r4 overdrive trans also being as the mounts are in same place and the 700r4 is moreless a turbo350 with overdrive. i have been around chevy my whole life and know them well enough, have built several s10's and even put the 350's in mustangs amongst other things. when i get my motor swap in my 240 with hicus done i am thinking about finding a good body for this same swap, pm me if ya have any questions i will help what i can

Couldnt you just use the stock fuel pump right off the motor. on the older motors the fuel pump was run just like the power steering pump, I would think that would work the same way, I dont see why you would even need to brother about the inline pump, if it had the clearence to fit, correct me if im wrong please

This is a very old thread................

[hotrod240sx]

You could just use the factory 240 pump and get a regulator with a return outlet like 1 that mad makes last time I bought 1 for a project it was about $85-90 I think. Put a gauge there to regulate it down and done there. The biggest problem I have found is doing the exhaust noone to my knowledge makes headers for a old school 350 or WBC into a 240. Best bet possibly would be to try and modify some shorties.

Or u can just be friends with one of the best welders in your town

you could definitely use the stock pump, but regulating them down causes a lot of extra heat and the stock pump just doesnt take it well, thats all. I used and aeromotive fpr and the stock pump, and it crapped out because of overheating (yes i had fuel in it the whole time it was never run dry)

and the shorties work well, blockhuggers w/e. i had to modify the drivers side one cause the flange was really close to the factory crossmember, but i just welded on my outlet pipe and it was all good.

doesnt matter if its an old thread, does anyone know of a thread that has a list of things you have to do, to swap in a 350?

[ShouldaHadaV8]

hey for $100 you could't go wrong, drive it till you sling a rod through the oil pan thats the goal with a 5.7 chevy. i got SBC 350 in my monte carlo i thought about putting in my 240sx but im not sure EXACTLY what all has to be done to get it in.... but i have seen it work in person and it was f_cking rank.

this post is old but if someone could shed some info on this swap it would be awesome

[Crazyirish]

It does matter. Start a new thread.

Heres how to swap in a 350:

Remove old motorMake custom motor mountsinstall 350

You'll have to work out the details in between as you go.

[rsagen]

Im sure it doesnt matter. Mods get pissed when you start a new thread for every little thing.

Unless you got something constructive to say go piss up a rope

[kyhunter89]

theres a unshockingly amount of misinformation of chevy knowledge on this nissain board.

LS motors aren't just in camaro and corvettes, they come in vans, trucks, and cars. everything from iron headed 4.8l to the most popular l33 5.3 iron block truck motor (aluminum block is the lm7) to the zr1's ls9 with 650ish hp. not all ls1/ls6's are aluminum blocked or even headed. usually the newer models are better.

the gen 1 sbc's came in 1955. yes there are emission motors (1971ish through the 80's) that where way down on hp. the answer and reason for a sbc isn't just hp its torque and the rpm it makes the torque at.

btw most aluminum heads arent based on the vortecs, very few are actually. vortecs are good in stock form compared most other factory heads.

to the OP 13to1 is too high unless you plan on mixing your fuel. with aluminum heads keep it below 11to1 as a general rule. instead of a corvette 4 spd have you considered a 2.8v6s10 t5 with the internal swapped out of a WC t5?

[kyhunter89]

if his motor is an 80 it have the fuel pump mounted, the later ones without a fuel pump hole just have to drill the hole out and swap cams to one with the ecctriec lobe. the spot to drill is already marked. also the 700r4 and th350 do not have the same distance from the bellhousing to the transmission mount (hence different crossmember) the driveshaft will also need to be 3" shorter with the 700r/4l60. if you really spending that much money on the motor, go find a t56 in a junkyard.

Following proper etiquette will take you far, both in online forums and life in general. Good luck with both.

[comatoseculture]

Hey BRO! How's life?

not good???? wow had no idea by your super helpful posts...If you have something constructive to say, please say it, OOOOOOORRRRR as had been suggested, piss up a rope you joke.

btw-good luck being a rebel/power control freak in both online forums and life itself. I hope it works out well for you.

LOL- I can tell you're the type that MUST uphold your internet honor...so I'm glad I made a new friend, can't wait to see how clever/well prepared/attempting to be more mature your response is.

edit: you know, I don't really know why I'm so pissed off, but I am. It's literally useless, I'm practically just as bad for responding, but seriously, this forum has a rash of "don't start a new thread/SEARCH you idiot" and then the counter "start a new thread, this one is old". Well which one is it? want us to search and research the old info, or ask the question? And I know that I am not a mod, but does crazyirish realize that he isn't either? Well, you aren't. So don't tell anybody else what they should be doing on here. Right? Or Wrong? Can I get a witness?

Overall, pretty good. You?

Not sure what that means. I always appreciate well-wishers though!

Hmmm. I can tell I'm just going to disappoint here.

If you have a question, chances are its been answered on some level or other. If it hasn't been answered, then you should by all means ask. A 2 year old build thread isn't the right place. If nothing else, It makes it harder for others to find later. Which feeds back into the whole search/find/new/old issue. I, personally, have never been shot down for starting a new thread. No matter how stupid the question.

I am totally a mod. I just forgot my login

[comatoseculture]

Well honestly, and I do hate a lil bit to admit it, I love the way you responded, and the fact that you explained yourself/answered my question at all when you really didn't have to, is truly appreciated. I apologize.

[Crazyirish]

It's all good man
