Re: what rocker to go with

Best rocker set out there IMO is Comp Cams Pro Magnums. They are made of chromemoly steel (not aluminum), they are MUCH stronger and will not fatigue and break like aluminum ones, they have a massive trunion in the center, and are totally rebuildable (most aluminum ones are not). Available in standard 1.5 and 1.6 ratio.

I have a set on my 350, and I love them. Never given me a problem. Only thing with these rockers is you do need to use the slightly longer ARP rocker studs (about 1/8" or so longer) because of the larger trunion - otherwise the polylocks will not have an adequate number of threads engaged. No big deal though to change rocker studs.

They cost around $270 or so when I got mine about 2 years ago now. HIGHLY recommend that set.

check out summits line of roller tip rockers these are stamped steel ones but they do have aluminum rockers aswell. These rockers will work great if your revving under 6,000.

Re: what rocker to go with

Ya i mean i could be hiting 6500 butt thats if i overev by accident. Im lookin for a pair that will do the job for around 200 bux. Any ideas?

Also i was toldthat if my lifters are okay that i dont need to change em. Should I?

Also pushrod wise. I found some summit ones for 50 bux. I was thinking of buying them to ensure my pushrods dont bend from the age of them. Or do pushrods need to be all fancy also? I dont think they do but im a noob at some of this stuff

If your lifter are in good shape keep them, getting new ones will just cause more wear on the cam lobes and youll have to slightly break in the engine again. Go for the comp cams magnums I've never seen them at $370 but summit has them for $160.. They are the best and theyre from comp so you can trust them.

Re: what rocker to go with

cc503 and that head setup will love 1.6 rockers...

that cam will be done by 6000 rpms so thats about where you will shift.

I had Comp Magnum roller tips rockers and loved them. 170 bucks a set you cant beat them. strong/durable enough for 6000 rpms.

Pro magnums are the full roller design. more pricey at 280-290 a set but nice super strong rockers. I'm gonna use them for my motor but i need them for the big spring pressures i'll be running and the rpms i'll be turning.

Depends on how much money you want to spend. For a street car i'd stay away from aluminum rockers... they will fatigue down the road, not sure when or how many miles but i've heard that from several places.
