The compression aspect must be blueprinted. Some shops may just put it together the way they get the parts and tell you its good. Best case scenario is to mill the block to suit.




That's true I did have the block decked.

It was a good thing my engine builder was such a cool easy going guy because during the build i made a point of stoping by on the weekends to see how everything was going. He was more than happy to show me the in's and out's and what was originally wrong and what he did to make it right. This aspect is a rarity in engine builders from what I have heard.

I agree that they do not take much to get them going, but it seems that good compression is crucial in achievieng it. Selecting cams and bolting on intakes and heads only works in fantasy land unless the motor had zero deck pistons to start with. My first builder just put in the pistons cleaned the deck and bolted on monstrous 906 open chambers...and gave me a motor that would not hold a tune to save its life.
