MRL roller lifters

That's the one I've been favoring. Good choice for a street 470 I believe.
I'll be using the 440 source 470 kit and Trick Flow heads. The 78cc chambers
should yield a 10.09 compression ratio. I'll probably stick with 1.5 Comp rockers.

I cam get the cam through my head porter but he thinks I otta get a new design ,he said it's old technology. He gave me a guy to talk to at comp .MRL likes Luanitti .My machinest is old school.Ive ran cams that I didn't think would work and upon a freshen up with the same tune settings yielded 2 tenths off the trailer with simular weather conditions.
Less Adams is the Mopar guy around Dallas Ft worth he ran my conbo on a high dollar program with maximum port work on Rpms and I had 600 hp @6500 rpm with 11.1 to 1 compression. So Indy or trick flows with 320 to 330@600 lift would be more
