Hi

Did anyone used CCA-CL21-223-4 or similar camshaft on a 400cid about 9,5-10CR ratio motor before? Cilinder heads are stock, dual plane intake and headers.
Your comments?

Thanks

fairly mild cam should work good!

Trust me here...I knows a little

Crower 271hdp 222/234@.050 .496/.486 cut it on 108 LDA and put it in +3 at 105 ICL

This is an awesome 383-400 cam.....talk the talk and walk the walk

With a cam you pay once and live with the results. Spending a few $$$ more to get a better cam is worthwhile. We have had other members with that same Crower cam in a 383/400 and they have loved it. Listen to Wize.

Summit cams don't light up my board.

In my early 1972 400 I used a 292-509 purpleshaft, and it was a real good runner.
It had the std. bottom and std. 906 heads with a Holley street dominator and a early Thermoquad.

It was one of my best street engines ever.

This might be a dumb question, but when installing a cam in a lower compression engine is it better to install it straight up, 4' advanced or 4' retarded? I would guess retarded would give a little more overrev and advanced would bump up the low end torque???

AMC,

For me it's more about knowing the head flow, the displacement and (primarily) where I want the intake valve to close. It's often better overall to put a slightly larger intake lobe in the motor and close it earlier, if you know how to 'get it right'it's a win-win, better overall power and no appreciable loss in low end torque.

When correctly chosen, Crower's mopar hydraulics flat out work, better torque and power on both sides of the powerband than the lobe @ .050 might lead one to believe.

As Dogdays said, I've suggested that cam on here for years, and other places both on 108 or 112 (depending on the app) and never heard nothing but great feedback on the choice. Nobody's run me off of here yet

Sounds like a good cam to try. Just picked up a new to me 69 Roadrunner after being Mopar-less for a few years. Has a decent runing 383, 4 speed, 3.55 gears. Could use a bit more cam though, would you like the tight LSA for this application Streetwise? Spent too much on the car, gonna be a while till I can build a stroker for it and I dont know what the internals of this 383 are. Stock intake, air grabber, Stock exhaust manifolds. Will have to do a compression test soon to see how healthy it really is.

Either one but the 108 would be torkier,...your car would benefit from a less restrictive intake up in Fort Collins the air is pretty thin.

108 gets up on the power faster than 112. I had a 112 lobe sep once and it was real lazy off the line. My 408 likes 108 way better.

I have a old crane cam 504/528 cut on a 112 I plan to install at 106/108 in my 400

FWIW a holley street dominator is low profile. It does give up low end tq but it does as well up top as anything else per the great intake comparo tests.

Thanks I'll keep an eye out for one of them also

That should also work well. FWIW...Edelbrock "re-brands" a lot of the old General Kinetics Hydraulic FT grinds from the late 60's and early 70's as their own. If you look at the old P.A.W. magazine ads, their S.S.I. (Super Stock Industries) "house/Econmy" cams are the same GK grinds that Edelbrock (and Summit) use.

i think it will be ok. i'm not a cam expert, but i think the eddie will have more bleed off, and reduce my compression more than the crower. so i will have less power, but less prone to detonate?

i at first figured i would have about 9.5:1 and told the machine shop not to mill the heads unless they had to. they had to lol and so my comp is 10.5. i'm crossing my fingers since i want to run super unleaded. maybe edelbrock does that on purpose, since the heads often need "adjustment" from what i have heard, buy putting a real bleeder in the package for a camshaft they kind of cover the mistakes lol
