I am doing some calcs for a stroker... I'm using the ever popular "AndreasStrokerCalc.xls" from MadXJ.
I am wondering what is the maximum material that can be removed from the 242? I was thinking of having mine decked, to bring the numbers back around to 9.69:1 with a quench of 0.0635... to do so, I'd have to deck the block .025 ... Is that a bit excessive? What are the issues I'm running into by removing this much material? (there are always issues)...
Also, How do you factor in cam specs to compute the practical compression ratio... With more duration, you can lower the CR, right? How are you gurus managing the math? I hate to see everyone ask you guys to calculate thier specific (and sometimes exactly the same as someone else's) numbers. I am a bit of a numbers geek on this, since I am poor and cannot afford to screw up. I CAN trust everyone else that has a running motor, but I'd ALSO like to see the numbers and understand thier relationships directly. I LOVE that spreadsheet... it is very illustrative.
Also, does anyone know the piston dish volume and compression height for the 2229's? (KB Silvolite) or the H802's? (sealed power/FM) or at least a source for the specs? I have had NO luck finding these.
I've got the 677's (sealed power/federal mogul) at 17.5cc's and 1.585 respectively.
I HAVE done a search, but found no specific tolerances for decking a block, or for the piston specs.
Thanks Gurus
