If you were going to build up an FI Motor on the side...

What would you go with. I'm going to be using my Vortech V9 to feed the engine, so big cubes probably not an option. Maybe a 396 but that's as big as I'd want to go. Mostly looking for something that can be put together in pieces as I get the money.

Thanks.

I recently finished my 408 Iron block (minus injectors and PCM) it has 8.6:1 CR....I plan on running it with a turbotech T-76 :D

the goal is 800rwhp on approx 16 to 18 lbs :drive:

oh, and beauty of it all is....it's gonna get dropped in a 5.0 body :eek:

i'd stay stock displacement (and did) max driveability, max mileage, max block strength, and cheaper!

that's my #1 option. Of course I'd want to go forged. :D

is there much advantage in the LS6 block over the LS1 block?

[MIGHTYMOUSE]

wouldnt hurt, but far as power holding, cant tell you if it would help or not yet as i dont know of anyone that has split a stocker.

I WOULD SAY A COMPLETE FORGED INTERNAL 408 WOULD BE THE BEST WAY !

I HEAR ANDY AT A&A IN Ca. has a hell of a setup with his 408 and procharger ! :cool:

[T-Rex]

I know one thing you do not want to use a 4.125 crank !!! :o

[AtomicVette]

4.125 would get you to like 427 wouldn't it? I think my little Vortech V9 would have trouble feeding a 396, let a lone a 408 or 427 :) I'll probably just stay with stock discplacment, and build for sthrengh and then turn up the boost :P or in my supercharger case, buy a smaller pulley :drive:

That's what i would do. Big cube motors are awesome, don't get me wrong, but there's also something to be said about stock displacement motors pulling good numbers. :cool:

[Packy]

346 with forged everything, a set of good flowing heads,cam, and good fuel system!:D Some of these set-ups can handle a lot of boost 12-15 psi and also make upwards to 600rwhp and still be daily driver tolerable to a certain point!:cool:

[mongse]

Agree. You shouldn't need 427ci thumper to run a 9.xx. Go with a forged 346 (or 348) and get a bigger blower. The V9 will just become a limitation.

Look into an ATI D-1SC, maybe an F1 (NOT an F-1R) or a Vortech V-1 T-trim.

[AtomicVette]

One of my friends is making 625rwhp on a 99TA 6speed, with a Vortech G-Trim on a Stock Cube LS1 and it has perfect street maners :D

[Packy]

I am making 503rwhp and 495rwtq! With a forged 346, stage 2 heads, mild cam, and ATI P1-SC! That is with only 7 psi too!:D :cool:
