Well my engine doesn't like the spacer as jetted. It has a lean stumble at tip in that it didn't have before the spacer so either I try and jet up and tune my pump shot or just change the base plate
I was whipped by a ZO6 Vette last weekend at the track He got hook on street rubber and I blew the tires off at the hit but I had his bumper at the stripe.
Talked to him after the race and he said he heard my coming about half track
