340 Static Compression Numbers and Test Procedure

cut domes down/ off lots of times without reballancing with street rpms
heavier is worse than lighter IMHO and those are not light pistons
depends on your heads if you should run thicker gaskets
ok with stock heads but I'd work on my combination if I had wedge heads
YR and I have different applications
No quench ok if you are reved up
If around town or towing then quench is esier to live with
cheeers


I agree. I wouldn't leave the quench at .080 or even .060 but once I get to .050 I call it good, especially on the Chrysler stuff.

I'd rather be at .040 than .060 but I wouldn't lose sleep over it. The OP has the chance to fix what he has for relatively little money and have something really cool.

I've long been a HUGE proponent of higher compression ratios for street engines. Some of the most miserable junk I've had to tune was low compression pump gas crap. Especially with a carb. To me, especially for a situation like the OP has, my minimum CR would be 10:1 and 11:1 wouldn't scare me IF the OP is willing to do the work to make it happen...like a custom cam, high quality cooling system, high end ignition system, a quality, tuneable carb and then tune the stuff.

To me, that is just cool stuff.

Again, thanks for the link Wyr.
