Uccr and squish should have been the first things to do before anything else. It's the base to any built engine. Envoyé de mon SM-S908W en utilisant Tapatalk
My 521 SS is 180psi with 30cc domes and 165psi with 31cc domes. I run 100LL and +5 timing. So, there is something wrong with your setup, 32cc domes at 150psi should be OK to run on pump gaz.... Do a uccr and squish test and report back. Envoyé de mon SM-S908W en utilisant Tapatalk
Give a call to Driveline for a low port Assasin cylinders and put 28 or 33 carbs with something like DMC pipes. On the other hand, banshee suspension suck balls, so maybe you can put some money on the suspension and just port the stock engine and make some small adjustments.
