I'm thinking about going to solid cam from Hughes HUG HTL4852BS along with the cool face EDM lifters and matched spings. Is this a good idea? 7541252-2011-12-2815.18.20.jpg (73 downloads)

The converter would flash to 4500 with 1.60 60ft. 7.23 at 96 mph in the 1/8th. Was just wondering if there was something better. Last edited by Todd; 01/10/13 11:24 PM.

I had one of those 533 hydraulic Mopar cams in a 383 and it work real well It was in a 1972 dart with 3.91 and a 9 inch converter with short tires, it ran pretty good until I ran it low on oil, but thats another story Mr.Cab Racing and winning with Mopars since 1964.

You can choose one or to get the most out of the combo or let one of the cam grinders pick it for you. I used Dwayne Porter for the solid flat tappet in my 493. He speced it and ground it for me. Also nitrided the cam and sold me the EDM lifters. It runs great with his cam in it and its a driver. No problem with cam breakin. He can spec a nice solid to get the most out of the combo. I could recomend a cam but it would not be as good as one of the pro's could spec for you. Ron Last edited by 383man; 01/10/13 11:42 PM.

Why not try advancing it farther IF you have PtV clearance.. that'll help the bottom end
