s13 chevy 350

i hope your planning on having an o2 sensor if you want that trottle body injection to work right, otherwise you'll pretty much end up with a carb...

just thought you should know

[wwiaftm]

Are you going to need to cut out some of the hood?

Those aren't double hump heads. Double hump heads were used on mid-60s Corvettes and a few other hi-po small blocks. That was the nickname given to them by hotrodders of the day based on the casting marks on the front. Yours are more like two slashes; the vintage double humps aren't as tall and are much broader, with rounded tops, if that makes sense. The other dead give-away is the more modern center bolt valve covers.

Doesn't matter really since it would cost more to rebuild them (valves, springs, retainers, 3 angle valve job, etc.) than either going with some new cast iron Vortec heads, or better yet, fully assembled aftermarket aluminum heads (most of which are pattnerned after the Vortec's anyway).

BTW, I've been restoring cars for 30 years and have done a lot of small block and big block Chevy's. I just happen to be hanging out on this most excellent site since I just bought my son a 240SX.

As awesome as this is going to be, I'll forever remember this swap as being done by the dude in the under armor air jerking it.

Appreciate all the info man 'cause I really need it, you probably just told me more about it than anyone else has thanks, Ill I know it's a 5.7L and it made my big body 20" spinners Caprice haul a$$ so now I want it to make my 240SX fly!

[2LO4URHO]

Ill definitely hang around man I wanna see how this turns out and learn from it at the same time, I wanna see some beast S13's running around

[Crazyirish]

Just my opinion but Throttle Body Injection = poop. After owning several carbuerated vehicles, I;m not a big fan of those either. At least not for a car I have to depend on. There are a million ways to inexpensively Fuel Inject a chevy small block. I suggest researching that possibilty first. Everyone I ever talked to online that went from carb to efi said it was the conversion was the best thing since sliced bread. (and we all know how good sliced bread is)

[crash n burn]

i helped my ex's dad dump a hillborn injection kit into his 78 monte carlo..wow, never again..they make some crazy hp gains..but not worth the time..

i'd say a pre 95 vh45de...mmmm VVT

[White Comet]

oh yeh, and a stock ls1 will kill any stock nissan engine.. if i had only thought ahead...

not necessarily, it dpends on what year and what its out of/ the ls was used in a lot of vehicle, detuned during certain years, some only put out like 160 hp, there are plenty of stock nissans that are faster than that

to the op- paint looks good, what is the name of that color. i just rattle canned my car a very similar color. it was semi gloss black

[ourmartyr]

the car is painted with laquer muscle car paint, jet black gloss. i have yet to sand a buff/polish/wax it... i'm waiting for the clear to fully harden. it says wait about 60days.

[BOOM_STICK]

Just my opinion but Throttle Body Injection = poop.

throttle bodies were just chevy's excuse to keep the EPA off there back. basically an electric carb

60days wow

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

[BOOM_STICK]

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

im not saying they're horrible or anything but the only reason chevy put them on there cars is because EPA said no more carbs and TBI is the half a$$ excuse chevy came up with for fuel injection. they didnt go to multi-port injection till early 90's i think...

im not a muscle car/v8 expert but if you want fuel injection i would go for a lt1. if you want carb'd then just get a 350 with a 4 bolt main. and if you really want throttle body injection try to find one with duel injectors out of an older camaro (cant remember the name)

thats just my $.02

[White Comet]

im this woudl fit in a 240 it would be sex

and whered u get teh paint from i might go w/ something like that if i dont go daytona blue, thank you

[Kataki_]

^^^ that would be the sex in a 240 bet it would fit too

[White Comet]

no way in h3ll that woudl fit in a 240

[qat727]

Great project. I had to give my V8 swap up, but I still want to do one.

And as for your sig image, that sure looks like a steel can, not an aluminum one.

[2LO4URHO]

Wow that would b teh sex, thats clean homie!

[DougRoost]

im this woudl fit in a 240 it would be sex

Damn nice big block Chevy. The Demon carb is the perfect crowning touch, too.

[White Comet]

glad u appreciate it, yeah its a monster but its still not done

The LS-series engines are aluminum-block chevy engines used in the corvettes and camaro's. nothing under 350hp was produced...

the LT-series engines were used in many vehicles

Almost... the LS was used in several vehicles including the c5, c6, 98+ 4th gen f-bodies(camaro/firebird), new gto, ssr, Trailblazer, and some of the new caddies. The lowest rated version came in at 305hp and was used in the 98+ z28/trans am. I think there is also a cast iron version as well.

[240wootie]

my bad, 305... just researched it again.. thanks me, lol

[eazye2000]

I'm glad someone else caught that before I was able to get back to this thread. I've been searching for an LS for a while now. I still want to track/drift my S14, that's why I'm trying for the LS. I may just say Eff' it and built an older 350 and do something to it that I would only do in my dreams... Don't get me wrong, I love the KA. I love displacement. Check the sig.

im not positive and i'll have to check but i thought eh 72 chevelle had an ls1, i'll find out today though

[DougRoost]

Nope. I had a '72 Chevelle SS with the 402 big block (396 .030" over from the factory after they came through with nicked cylinder bores in 1970). Back then the 454 was either LS-5 or LS-6. The small block used in the Corvette and Camaro (but not Chevelles) was the old LT-1, which was only built from 1970-1972, when it was replaced by the L-82.

The newer LT1 (note no hyphen is used in the new code) were replaced by the LS1 (exception: there was one year LT4 in the 'vette). The "iron block LS1" mentioned elsewhere is not an LS1 code and is used in trucks, SUVs, etc. (have one in our Suburban in fact but too lazy to go look up the code for it).

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!

yeah i just checked on it today, its not an ls1 just a 350
