To boost, or not, on my AFR 402? The car has much of the supporting mods needed..
W2W 402, 225 AFR's, Callies crank, Howard rods, FAST 90/90, T-400, 12 bolt
Set up for spray. I know the compression would be too high for boost.
Can I lower the compression with different head gaskets & how much of a difference would that make?
What would work the best for me, turbo, or supercharger? The car is not a daily driver, but it is street driven. Anything I end up with would have to be able to be driven without overheating in bumper to bumper traffic (cruising), and be easy to maintain. All this while running low 9's at the track. LOL.
I dont know if I'm better sticking with what I have, or going to boost.

New pistons would be your best bet to get the compression down. 72cc is about the biggest chamber you can get. I was in the same boat as you with 65cc heads and I just opted to start all over with a new motor.

You could get a turbo or supercharger kit, but what really counts is the cam choice and the tune. If you get the right cam you can bleed down some of the compression with overlap and have the car tuned properly. You should be ok. Go with a thicker cometic gasket, water/methenol injection, and you will be making big power on little boost due to high compression and large cubes. Call a reputable cam company like Comp Cams and they will be able to set you up with a custom grind after you choose the way you decide to boost.
