OK boys and gals,
Real simple question here (I hope). I don't want to turn this into a 15 page thread.
Need to know what brands of pistons to use with what gaskets to acheive proper CR (compression ratio) deck, etc. I'm after (as I'm sure many are) the path of least resistance. In other words, to try to do this without decking of cylinder or milling of the piston, etc. Just piston, gaskets and be done with it if possible.
Can somebody (prb will be mutiple people) provide the proper "formula" of brand of piston and gaskets for the following:
Assume all are 10.8:1 or 11:1 roughly to run pump gas
416 Piston (brand)
gaskets (brand and thickness)
425 Piston (brand)
gaskets (brand and thickness)
440 Piston (brand)
gaskets (brand and thickness)
I know that Wisco is notorious telling you that you are buying an 11:1 piston and what you get after using stock thickness gaskets is more like a 9.75:1. I'm still unclear as to how close JE and Ross are on their specs. It would be great to know the real combinations of manufactures to use (piston and gaskets) to acheive the proper CR, etc without milling and decking if possible. All here on the thread building a motor would benefit.
Another thing to consider is if most rate too high on the CR than actual, could I (we) just buy say a 12.5:1 and use stock thickness gaskets and then it would roughly equal out to 11:1 (I know that I over-simplifid this question somehow) or would that cause other issues? At lleast this would probably fix the issue of peoples cam timing being retarded from using thinner gaskets. Thanks!!!!!!
