how easy will it be to hit 350-375hp out of a 350 with lt1 heads (off the old lt1)? i want to use a higher rpm cam and eddy stage 1 intake manifold, and long tubes is it possable without spending over $650?

btw i already have the motor..this is if my dad lets me use it..if not im using the 350 out of his truck with votec heads

Whats the compression?

blkjck

hmm not sure, me and my dad are going to take it apart soon to see whats what..see if theres any cylinder damage or anything wrong with the heads..while its torn apart i think ill ask and see if i can use it and if he says yes ill go and order a cam and intake

It is as easy as a set of vortec heads and a small cam.

blkjck

well i will do that, but if i got the 350 with lt1 heads i only needed a cam intake and headers..and anything else i could afford..

Well, LT1 is going to need a special intake but the short block itself can withstand a ton of abuse.

blkjck

ok so what do you think is gonna be cheaper and maybe better? the lt1 intake or swap vortec heads and a intake that works at high rpm? i want a 350 with a big powerband at higher rpms cuz im gonna road race it and givin time race a friends dads 08 yamaha R6 :p..

x2 on the vortec heads and smaller cam. 350hp is a walk in the park.

Well, with 350 HP there is no real RPM to it. If you wan higher revs you will need higher end parts so it will stay together and you will end up with WAY more power.

blkjck

ok so heres what im thinkin in parts

vortec heads, eddy stage 1 street strip intake manifold, 750cfm carb, maybe balance the internals if i have money, all new gaskets, cam (not sure of the specs yet) headers, summit distributer, coil, and ignition box, aluminum pullys, and get the engine dynoed and tuned up...

and as i said then connected to a t5 with a aluminum flywheel, zoom clutch, rebuild the trans, maybe aluminum driveshaft, and stock ls1 rearend with lsd and 3.42 gears..


i think its a solid setup that shouldnt cost more than 2grand to do..maybe 2500-3000..

big hammer

on stock vortec heads .480" lift is the absolute max you can go. some guys go .460" to be safe.

no need to balance the internals on this project, it wont be a screamer.

a 670 carb should be all you need.

blkjck

well for the carb im working with what i got, i got a 750 in neer new condition sitting on a shelf in the garage..along with a extra ignition box and coil..

big hammer

vacuum secondary or mechanical?

blkjck

im pretty sure its secondary ..its the smallest carb we have in a garage full of big blocks lol

i usually go 650cfm max with my smallblocks, with some exceptions. but you should be able to get the 750 tuned in to work good. x2 on the vortec and small cam!

blkjck

lol well my dad is putting a 5.3 votrec in his 74 3/4 ton truck so im getting the 350 out of it..it rund good, sounds great..so its a good start..just make it more top end happy since its getting a 5sp..

buy a used stock ls1 and be done with it

blkjck

i dont have the money for a low mile ls1/ t56 hardwear and crap..

i want to put 4k into my whole car not just the motor and trans
