422 dyno fail

So you recognize the problem of using a bracket engine designed for light cars in a super heavy A body?

Best thing you can do with that engine is give it a RPM intake and a smaller and better cam.

Still waiting on you answering my questions.
What stall/flash and rear gear/tire size?

If you don’t want to talk about it, no worries.
3800 stall, 370 gear, 225 60 15. Using the recommended 750 Holley carb, put on larger eddy aluminum heads (ported polished gasket matched)
