hello ...here is something I have been working on...you will pay basically $600.00 for a set of forged pistons-dome or flat....so for hot street or light racing take a set of the Hyperteutic pistons, and cut the top off- then deck block then mill head AT least .060(more is desirable)....
Also you can have pistons lightened-and I can have this done for less than cost of a $600.00 set of pistons- this would work for a good 6000 rpm engine and have at least 10 to 1 Compression ratio...this is what I am doing to next street rebuild....
this will work but some might not want to do this much work..I have it figured out so far and is less than $600.00.... thought some might be interested in this approach.
