Were not trying to bring you down, but trying to help.
Set that motor a side, start looking in the adds, Find a rolling chassie Mopar and then build that eng to fit it!!!!!
In the idle to 6000 rpm range a well built 360/410 with ported edys/rhs heads WILL MAKE MORE HP!!
From 6000 to 8000+ Your combo will SMOKE IT IN POWER AND TORQ! hands down.
The better the head the more power it can make BUT ONLY AT HIGHER RPM.
Start looking for a roling chassie, you will be glad you did.
