With aftermarket heads, I try to use the XE274 cam, but with stock converter...I'd use that cam. I generally use the DEH cams with mild builds in mild street cars with stock converters, manifolds and dual planes so your close that way.

ok, i pick that cam because i dont afford a 10inch converter and new rear gear
(3.91) right now . Next engine i gone go whit cc xe295hl and ported the rpm heads, victor jr intake and holley 850dp./

No mopar no life
 
The DEH series cam is designed for exhaust manifold engines. They have the extra long duration on the exhaust side. Since you have headers, I normal EX series cam or stouter will do well.
 
me again, have some one test this cam and what do you think about it ?
How much hp/tq...can i get 500hp whit ported edel heads flows 260cfm ?
 
some one here have experience about cc xe high lift flat tappet hydralic cams?? Or is it a new line of profile?
i have one xe295hl and i want to hear what you feel for this one, good/bad !?/anders sweden

I used that cam in our 410 we just did. Hot street cam, made great power. Yes 500HP with ported eddy heads should be doable...they need good porting/chamber work but would be OK for that build.

ok thanks, i go for max ported edel-heads, 1200$ with valve jobb. dont want to change to "bigger" heads because i allredy have intake,roller rockers and headers. the headporter are grate for this job. Before this he drives
pro-stock serie for many years.
 
I have a custom grind Comp Cam for my 408 with Eddy RPM heads P&P.I had bought the Dougs underchassis headers(1 5/8) tubes.When looking at the tubes inside,they looked aweful small when matched up to the ported Eddy heads,so I sent them back and got the Hedman Husler 1 7/8 tubes.Should help much better flow,no restrictions.Good luck with your build.

P.S Solid roller cam .631 lift 252@258 grind #CRS 4006B/4013B R.110.0
 
1.5/8 for my 275deh engine stock 80is block
1.7/8 for the xe295hl engine early 70years block.
 
Sounds like you're building a sweet ride. I didn't catch the size of the rear axle. If it is a 8¼" or 8.75", you should be OK. I think that a 7¼" won't handle the power you'll have on tap.
 
8.25 : 3.21 sure grip for 275deh engine this summer and for next year 8.25 : 3.91 sure grip for xe295hl engine
