I recommend the SD Performance 342 cfm heads along with his modded victor intake using their modded 72cc chamber to what ever compression you want to run.
Bigger cam on a 112 LSA.
Dominator is a must if you plan on 10 flat or quicker. I recommend Pro systems and tell him your combo.
Gear and converter are a must. Call PTC. They work right out of the box!! You can run around a progressive 200 shot with a N/A converter but can start blowing thru it depending on the design.
Same with gearing and rpms N/A as compared to quicker ET's and nitrous.
Open up the wall clearance for bigger shot. Same deal on the rings. More gap in your second rings too. Napier 2nd with lower oil ring tension.
If your gonna try more then 250 hp with std Ross pistons. Coated the tops ad use the nitrous type top rings.
