Looks like this one...
Drops me down to 9.98 CR due to 72cc heads.

That's not terrible.
Oh yeah sorry two kits. 8cc pistons then 20cc pistons. I have the 20cc pistons. I’m supercharged. With my heads and gasket I’m at like 9.3

:hmmm2:

I have reading to do.
+ i was not happy with one of my rod bushings anyways...
Pistons were sketchy, i expected made in USA, I got Made in india.
"Matched set" = not matched at all.

what's another 2k at this point really...

Man, that just seems like the AFR heads i have are telling me to do this please.
And my cheap ass pistons are complaining that the AFR heads are calling them lame and other names....

:jester:

That would give me more low end too.


Overkill for what i want, yes.


Or maybe...
:hmmm2:

Well from the crank rods and pistons. Only the pistons are made in USA. Idk where the crank and rods are but summit don’t put their name on junk. I was happy with the quality when I got them in my hands. Tons of people using hem now days.

Forged pistons require coming to temp before use more so than hyperutectic. Forged grows with heat while the others don’t. So you will have rattling and damaged skirts if you don’t let them come to temp before driving.

This is overkill for me and I’m at 700 range. This is insanely overkill for you.

Don't know if i will do it or not, but this has me thinking
+ the specs are all there.
I can always copy it in slightly lower quality parts...
