Can you share the specs on your new roller cam? Mine is a 225/230 with stock heads. I'm wondering what kind of power you will get with new heads.
Thanks,
John

Good luck. Looking forward to your numbers. It should do very well with the big valves and that cam.

When you post your power numbers, would you mind also laying out the timing figures you end up with. Also, what heads and compression are you running. Thanks.

Hope it makes some big power.

Nasty! Congrats on a great result. Now go out and get some sticky rear tires- you'll be needing them!

Oh yeah, you did good. Thanks for the info, I'm working with another 454 owner with a Chris Straub hydraulic roller.

I'm very curious to know what pistons you have in that beast and how much valve to piston clearance you have. Did you need to relieve the pistons for clearance? Those closed chamber heads can present some challenges in that respect, especially when combined with a healthy cam that really hangs those valves open.
