If you want to make power yes, but I don't. I'm content wandering around the high 200's with a cool blower whine.

Haven't broke the trans yet. I'll probably break it now won't I.

Regardless, I'm not interested in a $3000 trans just to hold 350-400 WHP.

Why would you use l67 heads? Then you have to top swap it anyways.

Leave everything alone, only reason to modify the valve train is if you did a cam or rockers.

The 350 whp nick said, is with stock cam.. You add even just a gt cam to it.. You're looking at around 400 whp

TGP- 266whp- 10 PSI, intercooled CT kit PT 61, M90 block off, 2.5" exhaust, 42lb injectors, CT PCM, , L67 MAF, 42lb injectors, 18" wheels

TGP- 286whp- 11 PSI, Intercooled, CT kit PT 61, M90 block off, plog, 2.5" exhaust, LT1 MAF, ZZP PCM, 42lb injectors, Racetronix fp, 18" wheels

TGP- 346whp- 12 PSI, Intercooled, CT kit PT 61, M90 block off, plog, 2.5" exhaust, cutout, LT1 MAF, ZZP PCM, 42lb injectors, Racetronix fp, 1.9 rockers, 16" wheels

Ideally you'd use L26/L36 top end on an L67/L32. You get slightly better flowing heads, much better LIM/UIM and low compression.

Which you'll want to "get to" if you're putting an L36 LIM/UIM on your L67.

You made a claim, I offered an alternative perspective.
















bro.

injector bosses reduce flow.

Might as well build the thing properly right?

You really think it's gonna matter?

Most people don't even dyno their cars.

You're leading them to the world of things that aren't going to make a difference on the butt dyno, which is what all GPF cares about.

Nothing makes a difference on the butt dyno for more than 3 days.

Means you need to do more research right?

I agree with that..

As for cam, I'd go XP for a daily driver. I just did a top swap and plan on camming maybe next year with a XP.

I don't think you should feel like you have to go turbo, you mod your car for fun, not necessarily to squeeze every little bit of power out of it. I'd save the headache and top swap with the parts you have now, you will love it. Maybe even save a cam for later? If you do everything at once you'll have nothing to do til later
