+1 on what everybody has said about Bob. He's the man as far as I'm concerned.

I'm actually local to you. Live off Rt 4, south of Lebanon. I've been dealing with Bob for a few years now, and have 2 of his cams. I CANNOT speak more highly of someone. For the little amount of money I've spent with him he has SPENT a great deal of time with me on the phone, countless hours, and always been good to give advice. I would HIGHLY recommend you call him. That being said I have a cam I had spec'd out for a 502 that I'd be willing to get rid of, and would probably meet your needs quite well.

It was a cam ground by bob, on a 496 core, so it has the 18726543 firing order.

It's on a 112 LSA. 234.5/240.8 duration. .6462/.6298 lift. I can send you the entire cam card if you're at all interested just PM me. I actually have a plethera of random big block parts I need to get rid of.

Either which way you're going to want something with some decent lift and lower duration for your application. Good luck.
