Hello to all I have a 1970 bb 383 Charger with stock manifold and a Edelbrock 750 holley Probably 9 to 1. Stock iron heads. 3.23 or 3.55 rear gears. 727 for a trans. Last year lost the cam so I bought a Edelbrock Performer manifold for it and looking to hear suggestions on what cam to go with ( not a roller ) I was also thinking of a holley ultra lite or a quick fuel 750.. This is a street car that we sometimes drive on freeway. Looking for a good sounding cam that will work well... Thanks

Welcome here. I would suggest one of the Summit house brand BB cams (2 choices, near stock or a hair above that) OR get a hold of Dwayne (fast68plymouth) a member here

I would caution against over camming your 9:1, 3.23 gear, auto 383. what "sounds good" may not drive good. Wise words.

Thank you

Thank you I've used the comp cams 21-305-4 (magnum replacement) in 440's before. thought it was a little too torquey for a 440 but might be the ticket for a 383. the comp cams 276/.464 lobe (single pattern) on a 112lsa might be torquey enough. coupled with the proper spring should be trouble free and work ok with stock rockers. retainer to guide clearance is an issue with stock heads so be careful. stock magnum springs won't take much lift.

For a stock 383, the Crower 267HDP is the real deal. P/N 32241. It's as big as I'd want to go on a stock 383 which is, as stated above, notoriously easy to overcam.
There are others but this is one that works. Crower online catalog page 98.
I absolutely love how everyone says get someone to spec the cam for you. And then we find out that same someone has already suggested three off-the-shelf grinds. What he does is use his experience and then looks up the available cams. If there isn't one to his liking, he looks up the lobe numbers in the Comp lobe catalog and calls in the order. Comp will grind one just for you the same way, and it doesn't cost much more, if any, than a shelf cam. So will Bullet, and many many other cam grinders. But the guys who give advice are not inventing new lobes, they are just specifying something that they "know" will work.
There is no magic in specifying a cam for a stock 383 Mopar engine. The range of optimum durations at 50 and LSAs is well-covered by the aftermarket. There must be 20 camshafts by different grinders that will work nearly identically in that engine.
I think the most important function of someone like Fast68 in picking a run of the mill usage cam is preventing the buyer from buying too big a cam. In the long run, that is a pretty important function, seeing how most of us are living by More's Law:
If some is good, More's better, and, Too much is just right!

Well said Another important consideration is the skill level of the installer. You can look a little farther outside the box if the installer is good at tuning and working through other possible fitment issues that might arise(needs different springs, pushrods, etc).

The real benefit of calling Dwayne for a cam is his personalized service. He will take the time to discuss with you all of your options, listen to what is important to the buyer in terms of their goals and all the other supporting components, and then he will give you an educated suggestion based on years of experience and dyno testing. To me, this is well worth the extra money, which isn't that much. I know I can call comp myself (or pick one from a catalog) and save a few bucks, but i guarantee a Comp rep is not basing their recommendations on years of hands on experiences like Dwayne.
