Welcome to the AFR club!!! . Love those valve covers. Mine are drilled for perimeter VCs as well but I'm gonna be reusing my massive cantons since I know they will clear the 1.7 shaft mounts.

Looks like your build is gonna be absolutely sick! Care to give the rough range of that bullet cam?

Thanks man. I definitely like these valve covers. I heard a few people haven't had good luck getting the Canton's to seal on AFR heads so I sold mine and got these from AFR. IMO, they look a little taller than the Canton's I had.

Without giving away LE's cam specs, I can tell you that lift is around .650, duration is around 250 and LSA is 112.

I am sure you will remember and others would like to know

I dont see that much of a difference?
Those are the 195cc AFRs being compared...the 210s and up are a whole different monster .

The TFS heads are great, no doubt. For an all out build though the AFRs have enough advantages to edge their way out IMO.

Ahh I see, thanks for the info I'll keep that in mind if I run into any snags with the cantons.

Cam sounds nasty - I just wanted those rough numbers for curiousity sake . Good luck with everything!!!

That car should be sick, 450rwhp seems conservative.

Damn man I think everyone is going 383 and a LE cam LOL. This makes me want to get mine finished even faster.

Any pics of that ps/ac relocator? I can't find them on Speed Inc's site.

Plan to do a dyno tune next month with Moe Bailey. We are sitting at 440RWHP/434RWTQ
with just a mail order tune and rich A/F. Should hit 450 RWHP. Kept my 230/236 XE cam that MTI installed. Strong low/mid torque. Peak HP at 6400 RPM's now.

30rwhp over ported stockers with the baby 195s out of the box is nuts .
