What was your compression ratio and cam lift?

Thank you for telling me this, I was thinking my heads were the problem...

The .020 degrees difference in cam shafts , What would you think it might be worth in power? Just a guess....

It's actually a .030 over 428 block with a 455 crank. So it's basically a .010 over 455....459 ci. Compression ratio is 11.25 to 1. My heads are 76cc's.

I'm going to guess maybe a tenth or two. Years ago I gained 2 tenths switching to an 8" convertor from a 10", same stall (4800). And I gained 2 tenths switching from a th400 to a Powerglide. It's all in the combination of parts that go along with the engine. I think you will gain some also if you also switch to E-85.

Sounds like you went through your growth spurts too. Is this the motor that's in the video you have in your sig? I thought of going e85 but never got to it... I like being able to stop at any gas station..

I think I might try making the extra hp with the cam . The nitrous is starting to sound like the wrong way go now...

What lift are you at?

Thanks for all your advice...

Yep, it was in there in that video. It's sitting on the stand right now getting ready to get put back together for a spare.

Yep, a lot of growing spurts over the last 22 years I've owned it. It started at 11.44 and I've gotten it to run 9.38 best so far. I'm running the same cam in my 525 engine as I did in the 459". The lift with 1.6 rockers is .704 before lash.

Sounds like your car evolved in a positive way, I hope I can do the same...

Good luck racing in 2014 . I always liked watching your car run... Gotta Love them wheel stands you do...
