Low Comp. BB Chevy
 

I know this is the Stock and Super Stock Tech forum but I thought you guys would have the most experience running low comp. engines and having good luck with them. I have a 522 ci. BB Chevy that is a 9.6 to 1 comp. engine that I want to be a really competitive bracket engine. I was told that it won't be that competitive because it doesn't have a compression. It's going into a all round tube very light weight Camaro with a glide and 4 link rear end. I watch some of these stockers run dead on a lot. I hope you all can guide me on the right path. I don't want to rebuild it because its fresh.

Not a problem in the least.

By the way, the winningest (is that a word?) car in the history of NHRA runs a low compression combo. :)

Re: Low Comp. BB Chevy
 

You can build "compression" (cylinder pressure) with careful camshaft selection.
For what it's worth, back in the old days when I was Bracket Racing my Camaros (smallblocks) I tried to build as much mechanical compression as I could. The higher the compression, the less a combo seems to be affected by the weather.

low compression will be fine bracket racing, the main thing for consistency, isn't how much compression you have,but how well it is sealed up, a good sealing engine, valves,rings etc. will be more consistent than one not sealed up well.
Like Billy said cam is different in low compression engine.
