340 stroker 422

.070 head gasket will equal 11-1. If I calculated correctly

For what it’s worth, I’m running a .030 - 360 w/a zero deck flat top pistons from sealed power (C116HP), TF heads (60cc) .039 X 4.04 head gasket which works out to 11-1 (11.09-1 actual) and a Hyd roller comp w/a 224 intake duration in pump 93.

No problems, no worries.

He will have to work with the distributor timing. That’s it.
The only way he can run what he has set up now is with a mix of not straight race fuel. That will allow the best timing curve and power output but… but….. that will take a bunch of money to run race fuel all the time. I don’t care if miszny is super rich! Needing that kind of fuel is not at the local gas station and limits driving the car and it’s fun since he will need a gasoline truck following him everywhere.
