Interesting thread.

When I built this current engine (540 Hemi), I was conflicted as to whether I should go with a solid flat or roller cam. It is primarily a street combo, so durability was a prime concern. I asked on here and I asked quite a few experienced Mopar engine guys about which to go with.

And just like this thread, the experiences were fairly well split between the 2. No clear cut winner.

Since I got the reciprocating assembly from Ray Barton and he has a little bit of experience in this area, I went with his recommendation which was his tool steel flat lifters.

2,000 miles with VR-1 oil and no problems.......so far. But I will keep an eye on the lobes and if I see any problems developing, I will let everybody know.
