Gonna be alot of variances due to weight, gearing, trans, tire/wheel combo, etc...

Awesome! mainly im looking for 1/4 mile times, dyno numbers for stock valve heads. Some slight port work is fine. Im not interested in results from totally worked over ones.

Any car and setup is fine! Keep them coming!

From what I have seen stock 243's tend to be worth 20whp give or take
