340 stroker 422

Hi

I recently started building a 340 stroker.
The block was rough so we went with 4.100 bore. Walls are still thick so it should be fine.
I got:
- Molnar 4.000” crank
- Scat 6.123” rods
- Wiseco k0144a100 flat top pistons
- Very nicely ported RPM heads
- Performer rpm intake
- Felpro 1008 head gaskets .039” thick
- Hydraulic roller cam 232/[email protected] 108lsa .565” lift

Cam card calls for 104 icl, after retard of 2 degrees it came up at 104.5 degrees.

It was all nice till I realized my compression status. It’s going to be 11.83:1 static and 10.12:1 dynamic…

Is there any chance for this to work on premium pump gas?

Send it, you can get away with that compression by using aluminum heads. I built a zero deck 360, .027 Cometic head gskt & eddy heads, ran it at 32 degrees total timing. No problem running on pump 91 octane premium. Had it in a Dart Sport, ran 11.30's.
