With edelbrocks and basic p trim twin 61 mm turbos went 5.60's at 128 MPh at roughly 34-3500 lbs....definetly could have squeezed more but trans let go...

Couple years later put a set of 230 cc indys with gt 42 sized twin 72 mm turbos and went 128 MPh in the 1/8th with 9 lbs less boost....was definetly making quite a bit more steam with the indys...but I actually feel the turbos were most of the reason...

1300+ should be capable with edelbrocks with enough boost on our smallblocks
