Dave:

Other than the cam, intake and carb, that engine is exactly the same as the 70 LT1, with 11:1 pistons. Well, the distributor might be curved a little differently. It is the highest horsepower small block (ratings) offered in 69. You can probably see enough of the piston with a lightn and mirror looking through the spark plug hole to determine if they have been changed. If you need a pic of the top of one of those pistons, shoot me a PM with your email address. I just disassembled one of these engines. Would be a little

While there might be some other tuning issues, have you checked total advance (with vac pod plugged) at 3000 rmp? Check a little higher and see if there is a difference. If so, then you need to have the dist. curved to put timing all in by 3000 rpm. That said, I honestly believe the L46 cam is the weak link. I plan to put mine back together with an LT1 cam, or something similar, a Z intake and a 4053 Holley. I just like the sound of the solid lifters, for one, but expect quite a boost in performance.

Some of the Duece guys will probably have ideas as well.

Don't know of any mechanics in Jersey. But really, this isn't rocket science. I bet you can get it figured out.
