Let me know if you need stock length pushrods. I have a few sets of Hardened Crane stock length pushrods (nothing special) I'll let go for 25 dollars a set shipped.

Am I the only one who thinks that cam's a tad big for P heads??

aside from that, nice buildup. Should have some pretty good grunt downlow. & With a drivetrain like that on slicks you should turnout some good numbers at the track.

No offense though, i dont see it hitting that 300 mark like someone said. I say ~270WHP.

hit it with a 150 shot and i bet youll pull the wheels with them slicks

If I were you I'd be rethinking that cam choice. The XE276HR is designed around 1.7 rockers and not the factory 1.6. That cam has a peak torque that comes in around 5000 rpm and your heads and intake will run out of breath around 5500 so that only leaves you a 500 prime curve that will render the engine weak down low. I'd back up to the XE266HR and that will widen you up to a nice power curve of 1500-1800 rpm. The cam still leaves a little room if you decide to do a little porting on those haeds and intake. Not quite as much thump at idle but will be quicker down at the drags.

My apologies but I posted the wrong specs for the heads. I went to the site from-which they came "Tri-state Cylinder Head" and these are the actual specs of the heads:

60cc Combustion Chamber
Pedastall Type Rockers Used
Positive Oil Control Seals
5 Angle Valve Job
Stainless 1 Piece Swirl-Polished Under-Cut Stems 1.940” Intake Valves
Stainless 1 Piece Swirl-Polished Under-Cut Stems 1.540” Exhaust Valves
AWSF-32C Spark Plug
Springs Good to .550” Lift, (Hyd. Roller)
(129 psi @ 1.800” / 280 psi @ 1.300”)

Does this change things some?

I understand the track heat would of been a better match to my cam (intake rpm range 1500-6500 cam rpm range 2200-6200) but a few others and I agreed that it would of been too much intake for my combination.
