Default Pistons for lower CR 4.125 bore and LQ9 heads??

Where can I find forged pistons that can bring my CR down to about 9.5:1??? THe heads are fully ported and polished LQ9, I am thinking the cc on the heads is around 70+. 4.125 bore and 4.125 stroke.

looking to add a TT and need a lower compression. The dish would be big to get me down to 9.5:1

You will need ~26cc dishes to get your compression down to 9.5:1

This is assuming 70cc head, .057 gasket, .01 piston rise, 4.125 crank and stroke.

SOUP BOWL!!

Good Luck,
Kevin

We can do you a set of custom Diamond Racing pistons to fit exactly what you need. Just give me a call if you are interested.

Give Paul a call at Thunder Racing he will take care of you. As for the pistons, we can do those as long as you keep the rod length around 6.125". That should give us enough room to put that dish in.

Thanks,
