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.

Going from my 330 cfm heads to 342 cfm , what will that be worth for power?

Are you suggesting a 112 lsa for nitrous, or is it good for n/a too?

I have to ask a stupid question. If I were to raise the stall does this mean it gets looser too. Or can it be raised and still stay tight?

Yes. Head flow and Pontiacs leave a lot to be desired. When a simple 350 chevy head outflows a 455 pontiac head?
Yes I have seen major changes in power just in 10/15 cfm if it's proportional thru the lift curve.

112 allows pump gas, vacuuum and those longer LSA with nitrous are a thing of the past. 112 isn't even close to a nitrous LSA You can control your rpm range and hp curve with CL advance.

I wish I understood the cam part of your answer better.

I do get the cfm part about the heads.

Thanks...
