Biggest cam for 70 302

[66bluefb]

My next door neighbor is rebuilding his 70-302 stang and he wants to know what is the biggest cam we can use? The motor has hydraulic lifters and we are going to home port the heads and use the stock pistons which has little flycuts on them.

It depends on the valve size and the specific cam timing events.

He is going with the stock valves

I went with a Summit version of the Performer. The Performer RPM might be okay if you do go with deeper gears. But if you don't, you'll lose a lot of low end. I have a 3.35 first gear and 3:40 Tractionloc rear mated to a T5 in my 302 powered '65 convert. The cam and RPM manifold work well together. I also gasket matched the heads and had 351 valves put in when I had the heads done. I'm thinking of something between the two for the next engine because I don't care much for the rumpity-rump of the RPM, my opinion only of course. You'll need decent exhaust due to longer exhaust duration. And maybe Pertronix points eliminator and coil to light the mixture off too. This with a 600 carb (I went with a manual choke Edelbrock) and you should have a decent runner. Be careful not to overcam and be careful to use the springs that the cam grinder recommends.

factory springs will not work with much more than .460 lift. they compress, and then if the cam has anymore lift after the springs are maxed, rocker arm snaps in half; hardened pushrods help breakage of rocker arm. i know this one.

GO with some thing I have in my stang right now it has a nice lope it her. I was told to keep it under a 500 lift so I did because I have stock springs and heads.
