adam and craig :laugh: :silly: :pinch: :pinch: :pinch:

josh,
if,
big ol if.
there is a bit high compression,what is wrong with installing a thicker base gasket to correct any problems?

i have some plans for a stock bore 1015 with mtc 10 whatever to ones (that i bought from a member) and just figured if i had any pinging i would just space up the cylinders and head to make everything happy.

elevation plays into that whole compression deal also.

It sure does Leon. Moving the cylinder up by small amounts can drop compression significantly.

Good call Leon. Seems I remember some company that made base gaskets in different thicknesses. Save that, I can just stack in more layers of Frosted Flakes box DIY gaskets. They're GRREEAATTT!!! :laugh:

On a serious note, I guess that raising the cylinders via thicker gaskets does also affect cam timing as well. I'm gonna have to degree the K410's in anyway, but just sayin'.

a thicker base gasket is an option but u loose your squish clearance. it is better to mill the pistons. but lets not go there . everything may be just fine as Joe predicts. :)

i am running RC400 cams. they have 260* duration at .040". .429" lift.
i am actually running a .040" alum base gasket. but not to reduce compression. my block and cases have been milled to get them true to each other and the crank. some cases are out of true to the crank,from the factory. i selected the base gasket thickness to get the deck height that i wanted. this was chosen by my squish tolerance requirements. i like to run .040" squish to help prevent detonation.
when u take the motor apart save the old base and head gasket and measure and record the compressed thicknes. these #'s will come in handy if u need to make block hieght adjustments latter.

Is it only me or does it seem like Mark mentions his "squish clearance" every chance he gets? :whistle: :lol: Sounds like a personal problem to me...:silly:

Those pistons look like they will knock big holes in the head! :P

Geez Craig, I was only going to mention the nice lady that gave me a ride back to your place, you didn't have to spill the whole story! I really need to put this crap in my own thread, and stop hijacking Josh's thread.

I guess I'm not really one to talk.
