Going with that 220@050 cam was something along the lines that I am also considering and it’s a Howard’s Hyd grind I’m looking at with the use of standard Rhoads lifters in my 5.9 back by a 727 & a 9-1/4 w/3.55’s on 245/60/15’s. The Rhodes will only be on the intake. The cam is on a 108 LSA. Stall is 2500.
I did want to also use the A-500. This may come to pass later as the tails act has no provisions for a OE floor shifter.
My car weighs in about the same. You and I are in the mists of testing the same idea. But I have a ‘00 - 5.9.
So is my ‘18 Ram 1500 but i average 20+ on the Hwy and have done the best of 23.7. The aerodynamics of the Ram are a brick and it’s a heavy brick!
I agree. The Howard’s cam I’m looking at is aided with the Magnums 1.6 rocker. I have the math on paper somewhere. So I went with the approximate math Rhodes suggests is happening. Even with the reduction in lift, it gets some back with the 1.6 ratio. Just in the territory of the head needing a really good valve job for best effect.
Personally, I think
@Dmopower is onto something and will find out before I do since our builds are a little similar. As I wrote early in this post, my ‘79 Magnum has a floor shift I want to keep and the trans tail or mid section has no provisions for brackets to let the linkage work. I do t want to butcher the floor shifting brackets out for an aftermarket shifter.
Honestly, I’d rather put in a manual transmission.
