Thanks again Cliff,

Great to have somebody that gives good advice, this makes more sense to me then the bigger is better I hear everywhere. :) But first I need to read some books on the subject and of course rebuild my carb. :)

Cliff Ruggles:
You are welcome.   We consider the carburetor a very important part of the total combination.  One still needs to have well chosen parts for the combination to be successful in the first place.

We get calls in here daily from folks with troubled engines, poor fuel economy, poor power production, etc.  Many simply have very poorly chosen parts, compression too high or too low, cam too small or too big, etc.

With the Small Block Chevy engines, poor flowing heads with big combustion chambers, adding a thick head gasket from a rebuild kit, and some big aftermarket cam is a very common problem call we get here.

Unfortunately, without good flowing heads and a decent static compression ratio, the cam choice, carburetor mods, etc, are NOT going to help the problem.  It's just difficult to get air in and out of an engine, and make good power when the compression ratio is low AND the heads flow poorly.

The good news is that the aftermarket has stepped up with dozens of cylinder heads that are excellent, and many are very reasonable in price.

The cylinder heads should be the first item on the list for upgrades to any engine project.  If the heads woln't flow well, and don't make much compression, no other parts you buy are really going to provide a good end result for the project......Cliff
