Contact Bullet... I believe they do most of the 307 stocker grinds. Yes, you can get a "stock" 307 into the 12's, and a super stock style combo down deep into the 11's, but there are plenty of tricks involved beyond a cam swap. Venolia, among others, make stock legal pistons. You'll want more gear than 3.73 or 4.10's with that big of a cam. Do be aware that the windowed 307 blocks seemed to last anywhere from 50-125 passes when turning NHRA stocker rpm. Most of the guys have switched to sleeved DX or 350 solid main web blocks.
That's my car in the video... it's still on the CCC system with overdrive and has working air conditioning, so it needs low rpm torque. No doubt a bigger cam would go quicker as the engine doesn't pull over 5k rpm. It was meant to run that way, as the bottom end is bone stock. It would crack into the 13's off the computer with electric fans and the rear suspension changes I'm making, but I'm switching over to a BBO.
