402 ls2 motor swap need help
Hello All I need some help with my 402 ls2. Here is a break down on whats in this motor
SDPC short block (402) -15 cc pistons
Cam 226/226 580 lift 112 lsa
Stage 2 heads with a 65cc with .0041 gasgets (these are ls1 heads)
Had it put in the car with the new motor and then started the up.(motor was primed before stating) There was a loud ping/hitting (sounds a little like a tin can banging on metal. My first though was maybe I did not have Valve/piston clarence but the heads don't looked like they where milled.
I was also wondering could it be that with the stroke of the new motor could it be hiting the oil pan with the crankshaft?? Or is there somthing I overlooked??

Hopfully it will be done soon. I will have the windage checked I am preety sure you are right about it. I also called SDPC and they said the same thing.
