I'm being conservative in my estimation....

given the published flow data I've seen on RHS's and eddies, I'd think they'd be pretty close power wise, maybe 10hp more with the RHS's...but they'd also be 50+ lbs heavier.



So with a .557 cam do you still think I will get 17+ mpg? that'd be great! I like th idea of a tight convertor, too. I like those RHS heads but like you said..an added 50lbs...so I would want the eddies for sure. Anyhow, I will looking for the magnum motors now. Hopfully i can find one in a junk yard around here with low miles.
