I made a post on the Cadillac forums just to see who is still there. So I plan on going big with the motor first to just have fun before I sink 7 grand into a E-force and then go ***** out. I have a FAST 102 intake manifold just laying around so how can I make best use of that and make a lot or decent amount of power to the motor. I realize it won't be cheap because I'm going to need bigger everything. I'm just looking for what everyone has experimented with and seen the best results.

Are you trying to go H/C/I for now or what?

And if that 102 is just taking space up in your life right now I'll make sure you never trip over it again when you do go to a blower lol

Are you staying with a stock shortblock? If so some AFRs or TFS heads and a custom ground cam along with the fast will net you some good gains. Just keep in mind your not touching 500hp on the stock shortblock wih just h/c/i.

Actually he could touch 500, just needs ported LS3 heads, with ported FAST 102 and the right cam on a 6.0 lower end. Maybe a GT-11 or something a little more aggressive. I have seen it done, and no spraying as well

You will need a great tuner if you are goin to keep the lower end stock. keep her silly rich like 12.0-12.2 across the rpm threshold.

I am shooting for 500+ on the stock bottom end.

I've never seen a V1 hit over 475 n/a on a stock 5.7 or 6.0 shortblock. IRS and drivetrain in the V just soaks up too much. 500 is even a real stretch in an fbody. My buddy had Tony Mamo port his AFR heads and FAST 102 and spec him a cam and even he said itll make high 400s in an fbody.

I have seen it here on the G8 and GTOs...They share the same drivetrain as the V...You just have to insure you use the best synthetics and keep it all cool....

So much easier to get it done with boost. And IMHO safer. You don't need a ragged edge tune, or fly cut pistons with a cam that kicks open valves like a horse. You just need about 8psi (depending on method of induction) on an otherwise stock engine, you're there.

Its a honorable goal, big power NA on a bone stock lower end. Just don't get your hopes up too much. And remember, if you can quite make it to 500, try E85. That might be juuuuuust enough to get you there.

This.

Granted I have a 9" rear end, but I only got 442 with Tony Mamo H/C/I.

Well I don't mind replacing some of the bottom end it'll just take me time to save the money up. I just have no real good idea where to go. So far the input has been great I've been looking at parts all night

Im trying for 500hp 500tq

418 cid, 4.1 crank, .030 over ls2 aluminum, Arias 11.7 pistons, 235/250 115 cam. Gm cnc ls3 Heads, Gm ls3 intake, 1-7/8 Headers. 93 pump gas

How far along are you with that? You'll have to let me know how that goes

I will! The machine work is being done as we speak. Balancing and boring, floating the rods on the pins. No nitrous..So the short skirt pistons are going in real tight @ .0035.

I'd live to bore mine out but it's my daily driver and being on base all day working makes it hard to tear the car down for days at a time

Yea you need another car that's all.

My cam only Trans am was so much fun to drive that's where I plan to start with this car. Only ever made 375 but like I said it was fun and after doing it a couple times I wouldn't mind redoing a cam if I went with forced induction later it isn't too much work once the springs are replaced

I'll just find a decent truck to get me by and go all out with this haha

That's what my next move is too. I'm looking for a first gen Cummins Dodge. Not a fan of a dodge, but I am a fan of a Cummins with a 5 speed.

If you go on brute speed's website they have procharger kits customized for the V1. Build a good NA motor. It will only improve the way it runs under boost, as long as you don't get to prohibitive with the compression. Machined 243s, a nasty cam, an intake, and exhaust will get you close but all the research I've done/seen, power adders are needed to crest 500 ponies

what he said...same thing I'm planning...hoping for high 400 whp range. It's possible depending on how aggressive you are willing to have that cam but you can't cheap out on heads. You want the 205-215 higher velocity runner with the 346 stock cubes.

You'll be doing two complete builds as a max effort NA setup will have nothing at all in common with FI. Everything down to the piston ring gaps will be different. Pick a direction and do it right once.

When tuning NA, richen the fuel down low for torque and lean it out slightly up top for max HP. NA builds do not respond as well with a fat mixture across the board or fatter at the high end.
