Looking for suggestions on a solid mechanical / solid roller cam for my Hemi street/strip car . E-body 3600# 4-speed , 4:10 gears 28 inch tall tire. Would like something in the 550-560in lift . motor will be 10.25 comp .030 over Thanks

Any of the better known Hemi builders should be able to help you get the cam you want.

I got mine from Ray Barton. 565/547 with 250* SFT. I am very happy with it.

How many cubes, and what shift rpm are you shooting for?

5500-5800 I'm thinking

If you're really going to drive it on the street, then I would say the Isky ez roll lifters. But they are $$$$

What is the stroke? That's pretty important when picking a cam.

If that's all you're going to turn it why not a hydraulic roller?

it's a stock stroke .030 10:25 comp. I have a 524/507 MP hyd cam in it now . Would like to go with a solid or solid roller with more lift .Like the sound of a solid cam Hemi , I have the motor apart for freshening up now and thought it's a good time give it little power

I think you'll find that the duration is a more accurate indicator of the RPM range than the lift. Shifting your Hemi under 6,000 won't take much cam at all.

The .565/.547 250* cam in my 540 pulls to 6,800.

Me thinks the required spring pressures determine the life of the lifter.I found out the hard way.I'm on the same set of comp 848's since March of 04.Rebuilt for the second time last winter.
My lift is mid 6s with spring pressure low 600lbs over the nose in a street driven hemi that sees over 1000 miles a year and if I'm lucky,,,,,60 passes.

Picture was the old comp 829s.

"You like the sound of solid Hemi cam", do you mean the clatter of the valve lash? for what you say your RPM range is don't waste your money on a upgrade.

On your deal I would buy and use the Comp Cams282S grind, part number 24-308-4, and install it at 103 to 105 intake lobe center and use the lash as recommended, maybe experiment with both .004 to .006 tighter and looser to see what sound and driving you like the most
All the stock street hemi cams with mechanical lifters, 1966 to 1969, had .028 hot recommended lash
Tightening them up .006 to .012 made them a lot quieter and helped the bottom end power

I think it would be kinda hard to keep under 6,000 the way they rev.
I remember my buddy letting me drive his 64 dodge lightweight Hemi, nite and day difference from my 64 max wedge. Mine had a 5.13, his a 5.57, it hit the shut off (8500) on 2 & 3 because I wasn't expecting it to rev that fast. LOL

A race hemi compared to a pump gas street hemi is like comparing a 383 magnum to a 425 HP M.W.

Since its a street car I am guessing it will be pump gas ? Whats the pump in your area ? I can find 93 at some stations in my area but most are 92. Course I would keep that in mind when picking a cam. Or have a good cam person or company spec a cam for your combo as that's what I did. I had Dwayne Ported spec a solid flat tappet for my pump gas combo and its nice to know I can pull in any station in my area and gas up and the car will run good with no detonation. Good luck with it. Ron

Talk to Dwayne Porter (Fast68plymouth here on the board). Get a cam spec'd by him and you'll never need to worry if there's a better cam out there for your combo again.
