Cam for 70 GTO 4 speed
 

I bought a Mint Turquoise original WT 4 speed 70 GTO back in 2012. It was a one owner car for the majority of its life. A guy in California bought it and spent a bunch of money on it that it probably didn’t need. He rebuilt the motor and installed a Comp Cams 255 Dual Energy cam in it. I kept the car for 10 years and sold it to my buddy about 18 months ago. I always wanted to change the cam and put ram air and ram air exhaust manifolds on the car. I bought the car back and called Ames about the ram air manifolds. They said they should have them in 4-6 weeks. I am thinking about using an 068 or a Summit 224/234 cam in it. I had the Summit cam in a 69 GTO with a stall converter and it was one of the hardest running Pontiacs I ever had. The 255 Dual Energy cam has a lot of low end but it runs out of breath. It has no top end. It is basically a tractor engine. What do you recommend? It has 3.23 rear gears and AC. Also where can I buy the good Johnson lifters?

I would consider the 068 high-lift (summit 2801). Crowed 60916 or summit 2802. For near stock but better use the 2801 with good lifters. Don’t trust the summit lifters. I got mine from Spotts and they settled in perfectly.

I just bought my lifters from Butler.

If you can stand a little noise while realizing your engine is healthy this is where a set of Rhoads lifters would come in handy they would reduce duration and overlap at clutch release RPMs to cope with the slight loss of low end torque from the 2802 camshaft, just like the stall converter helped in that area with the automatic

I think the 2801 is probably the best choice for this car as I don’t want to lose low speed drivability.

Where the valve springs changed by the guy in Ca when he rebuilt the motor?

I think so. I need to look through the paperwork and verify that.

What's the current price of those? If you care to say?
