does anyone know what the stock cam specs are on a 66 383 4bbl ? Currently having my engine rebuilt and I want to make sure i don't screw myself when it comes to the cam. Still running the 516 heads.
Does the existing cam show wear? With the stock 516's there's no big reason to change cam.
The closest aftermarket would be the Comp XE series and I can't even navigate their site to look for it. Lots of people have been happy just throwing the simple Summit cam in if you're on a budget. Summit Racing® Classic Camshafts SUM-6400
The only Lunati I would use is this one. Factory Performance Hydraulic Flat Tappet Cam - Chrysler 361-440 278/288
I runnin a Hughes 2330 w/ported 516 w/1.74 exhaust valve heads in mine and love it! Hughes take advantage of the large lobe area to produce higher lift cams for a given duration, this is what the Hughes 2328 sounds like in my Bro's car with 440source heads. First time out of the garage shakedown.
You'd be happy with any Hughes from the 1620 up to the 2226. Dave at Hughes is the man to talk to about that, but I'm sure he's say the same. Good Luck

Im wanting to bump the cam up a bit but not to the point where it causes the engine to stumble. Bottom emd power not top end power is what im looking for. I didn't want to underpower the car either
Do your reviews and homework on it, there's lots of info & reviews, even videos of people using that cam to give you a idea on sound!Thank you Stubbs for posting those links, especially the Summit cam. That looks quite close to the old 2 barrel 383 cam numbers too, which is what I have and plan to build my RV 400 to. I also like closed chamber heads like the 516s I now run and some 915s I hope to soon obtain. You might be a good source of lore for me, especially next year.
Yes and he seems to want to stay near oem specs. If it's not worn then why not just use it again? Cams don't automatically need to be replaced just because you need to do rings or bearings or valve guides.
