Engine is a 1965 225. Basically stock except for a super six manifold and a 350 cfm holley. Turbo is a TD04. Anyone have a good cam grind for this setup? It'll be between 10-12 psi. Daily driven, so I wouldn't want something too lumpy.

I'm working on turboing mine right now. The advice i have gotten from my turbo friends is that low overlap cams work well, something like an RV cam grind. I am just using my stock cam until I have driven it under boost for a while then i can decide better where to fine tune from there.

My advice would be to cruies over to the FAQ in the boost section that I built. I will cover about every question you can come up with. For short, a lot of people will recommend the stock cam. Shaker223 ran sub 12s with all stock and 340 springs.

Actually, it was high 11s but with alot more boost than you are planning. A stock cam will make plenty of power. Spring upgrades are needed. Just watch the backpressure.

So 340 springs would work fine? And also, do you think with headwork (engine builder valves and port job) at 10-12# could get me into mid 12's? 2900# car, 2.76 gears, rebuilt 225/904, td04, super six mani, holley 350cfm.

Shimmed 340 springs would work...IIRC 120# on the seat. You should be able to get into the 12's with the mods listed.
