Don, what motor are you running?

I'm not up to much on the later stuff, but it seems several years ago a friend of mine mentioned to me that they had a new (Camaro ?) that kept coming back into the dealer he worked at and the timing was all over the place. They finally figured out that the factory had left out the cam button and it was allowing the cam to go back and forth changing the timing.

Mike P,

That is very interesting! My engine is a rebuilt 1976 L-48 two bolt 350. At only .030 overbore some builders tell me the block is like gold. The person who built the engine is now deceased but he built a lot of engines for circle-track racers. He shaved the stock heads, gave them a three angle valve job and cleaned out the exhaust ports. I will investigate the cam button theory. The short block was rebuilt with a 0.010 grind on the crank and used a hypereutectic set of pistons. The cam is the same as the stock 1976 Z28 with Z28 springs. The heads were cced to get a 9:1 CR. This is a very mild engine but the fiberglass roadster body is light enough for good street performance, at least for me! Actually the initial acceleration is probably due to the low gear in the 700R4 trans although the 3.55 rear takes away some acceleration Thanks for the idea.
