Improving my 360 combo. Need advice/input

BobsDart said
I have a similar cam, mp 284/528 solid in my 360. auto 2500 conv and 391's, hooker super comps, airgap/ 650dp w/proform center.The car is a blast!!!
If the m1 is a single plane too much. I had that and went to the airgap. A 1" space might help you out with the performer... Plus better exhaust and gears!!! Mine works the best w/18-20* intial and 36* total advance @ 2500.
Just my 2cts and experience...

I have a 1" 4-hole spacer ready for the RPM performer, the 3.91 pumpkin will go into the car and the initial timing will be the same as your's but my total advance will come around 3100. The M1 will go to a good home. I thought about the Air-Gap. Not enough engine/cam to justify it.

Dave you might try going to Comp Cams website and put your proposed engine specs into their cam selector to see what comes up.

Yeah I used the comp cam quest program and the XE268 and XE274 were the best fits. I have heard most people are happy with them except they are noisy. They try to get you to buy the Thumper $$$ cams too when you use that program.

**** can those proform rockers before they disentegrate.I,ve seen too many sets smoked hanging around the machine shop.adjusters are crap and they break.

Yeah Pete, made in China crap I have been told. Would love to get my hands on a nice set. There was a MoparMuscle article I remember that compared all the roller rockers. I will have to dig that one out.

If I change out the cam, I'll be getting new roller rockers. The pushrods are Crane, the springs are from Comp. So I should be good there as long as the springs were done right and have the correct spring tension for the cam i choose.

Been looking into the Racer Brown cams and was going to give Jim a call to see what he would recommend given my future setup.
