I think I’m going to go with either the 65-72 HO (9779068) or the 66-69 Ram Air (9785744). I think paired with a pair of the large valve heads that cam would flow nicely, and hopefully will continue to operate ok with stock heads until I can get a set of the large valve heads. That and I’ve found some cheap “stock replacement” models of those very cams. Any other advice in terms of installation or tuning with one of those camshafts?

Thanks for the help frosty! I’ll be sure to look into this more

Hi Joe, welcome to FP.

The nice thing about Pontiac engines is that the fact is they are so interchangeable. For heads, I recommend trying to find a head with 2.11 intake, 1.77 exhaust valves. These are the biggest factory valve heads Pontiac made. Add some port and polishing and these will do your 350 nicely. Those heads are listed below. You can find them online and at swap meets, you just have to pay attention to casting numbers. Forget about the RA V heads, they are super rare (and expensive). The other RA (Ram Air), HO, and Super Duty heads will also be expensive but you can find them but you have to be patient and your wallet has to cooperate. That said, all the other heads can usually be had for less money.

 

 

As for cam specs, that sort of depends on what you plan to do with the car. Is this a street car, street/strip or race car?

I’m looking nice street ride, but I don’t mind a bit of rumble. 

I’ve got a 1971 Pontiac 350 with an Edelbrock performer intake (part number 2156) and a 650cfm Edelbrock AVS2 (part number 1906) and I’m in need of a cam swap. What cam/ cam specs should I get? If possible I’d like the install some roller lifters/rockers but I’m no expert on this sort of thing so I’m looking for any advice. Also while it’s a long way off what heads should I look at getting? I plan on having them ported for the 650. (I don’t know the head code on the 350 now off hand so I don’t if if I can use those or not) I also possibly have access to a pair of 1959 389 heads but I don’t know those codes off hand either. Any help would be greatly appreciated.

Yes this is perfect. Thank for the advice!

I’ve got a 1971 350 motor that I want to get some more power out of right now, it’s already got duel exhaust but that’s really the only “performance” system on it. I’d like to get a new intake manifold and maybe new exhaust heads but i don’t know where to look. I don’t have boat loads of money to throw at it and I still need it to be a daily driver. So no turbos or superchargers. I’m happy to hear any suggestions. (Go check out my baby too. The names LuLu)
