hi pat this is what we did. we decided to use the 4.250 stroke crank and the h-beam 6.535 rods, we got some speed pro hyper pistons with a ch of 1.525 a dome of +.100. we decked the block to 10.195 which according to my poor math should put us at about -0.009 in the whole then we got a nice copper gasket that according to specs should give us a 0.032 compressed thickness which should give us a quench of about 0.041. My question is should i deck the block more to get a smaller quench or is the 0.041 okay. The math formulas are driving me nuts but it should give me a compression ratio of around the ball park of 9:3 with the 119cc aluminum heads. they have large intake and exhaust valves. Now the next headache is choosing the right cam were thinking hydraulic or solid roller cam between a 625-675 lift but have idea on the duration yet. i figure it has to be a longer duration because of the longer stroke? another thing is the pushrods for the rocker arms since i decked the block i probably need to resize those, don't i? and how about the distributor? this might be my first and last stroker lol.
