titan 240

im wanting to swap the titan motor into my 73 but i have no cule on how much more it weighs than the stock motor. and other than the drive train what else do i need to beef up to hold the extra power?

brakes, suspension, the stock diff can handle the power but unless you add an lsd you'll be constantly spinning 1 wheel, domestic V8 swaps has been going in since the 70's, and nissan evne did a few back int he 70's with their own president v8

and the stock L6 is pretty heavy, aobut the same as an orin small block doemstic, so the aluminum V8 is likley about the same maybe even lighter than the L6

The Titan motor actually weighs round abouts the same, maybe a little less, but with a bigger trans it pretty much comes out a wash. The hardest thing about the swap will be the manual trans if you want one and the engine is HUGE. you'll have to make a new intake manifold if you want it to clear the stock hood and exhaust clearance especially on the drivers side will be an issue.

im guessing that i will be needing a larger radiator also..i have one out of a 280 with dual 10in fans..to small? will i need an aftermarket fuel pump, something like a walbro 225?

the stock radiator might actually work out, but if the inlet/outlets are int eh wrong location a 22" GM radiator is popular for domestic V8 swaps

as for fuel pump your 73 should have used a mechanical pump, watever pump you use it will have to be external and to feed an engine that size you'll likely want a 75 280z gas tank which has a larger feed line and already has a return line

I like the MSD pumpmyself, and it's bargain priced
