New 340 Edelbrock Performer RPM Air Gap intake $240

Can anyone walk me through calculating compression ratio with different pistons? Im chair flying a few options and would like to see what piston will put me at 10-10.5: 1 on a .030 318. I’ve tossed around heads from aerohead racing, mostly because of ease and cost. 68-70cc open chamber, 160cc intake port volume. 1.88×1.60 valves. Any input would be great, just never been too savvy with the numbers. Thanks guys! Glad to be back.

I have finally got the shift points adjusted by shortening the upper rod at the carb but I have never had full throttle kickdown. My qustion is as I shorten or length the rod where it connects to the carb I am changing the travel at the transmission which is keeping the tranny lever from travelling the full way back which is keeping it from full throttle kickdown.

I don’t get it. If I adjust one end I am changing the other end and visa versa?
If I change the lower rod to get full throttle…

Will a 69 318 have thick cylinder walls? I have heard that some years had this.

Looks like we have a birthday girl with us today!!!!! Happy 29th birthday Leanna!

What do you guys use?,
how does it work?
how many gph does it flow ?
