383 Mopar Motor... All original Commando V8... WHAT CAM would beef it up a little?

65 Plymouth Fury III... Looking to throw a cam in it because I'm taking it to the machine shop and having the block cleaned, port & polish job.

What cam should I use?

I'm sticking with the stock 2 barrel Carter for now, but I will be putting a four barrel on it later.

I want to drive it daily, so nothing too crazy on gas mileage and ****, but I want to be able to stomp it and have some fun too.

Here's a pretty good selection of Mopar Performance Purple cams and kits. Take your choice.

Centerline

sorry to up an old thread, but I'm going to go get a cam within a couple weeks for this thing finally.

I got the heads completely rebuilt, thinking about porting them out a little myself, and port matching an intake to it also, along with a 4 barrel carb.

I want to stay stock heads (I'm kind of regretting putting a different intake on it even, I hope I can find an OEM 4 barrel intake for it that I can clean up and port a little, if anyone has one please email me @ dizturbedone@gmail.com)

with stock spec springs and heads (except I had them put new seats in for unleaded of course) what kind of cam am I safely looking at?

Cam, lifters, pushrods, hone the cylinders, piston rings, bearings (main, rods & cam), 4 barrel intake & carb, headers and 3" exhaust all the way back are the plans. Nothing too crazy, but a solid running motor to haul that big old boat around (1965 Fury 4 door sedan)

I'd like the long block to appear OEM...

I really need some help, I'm clueless when it comes to the math of it.

I would go for the Mopar Camshaft Part # MOPP4452783MRE (Hyd. - 268 / 284 Duration - 450 / 458 Lift). It runs about $160 and is the same cam they put in the high performance Roadrunners and Super Bees in the lat 60's. It's a great muscle car cam that gives really good driveability but still has a nice lumpy idle.

When it comes to a stock 4 bbl. intake just look on e-bay. They're a dime a dozen.

purple cam 2783 rocks(4452783). purrs just right. GOOD factory technology! big time!


the 509 purple shaft(4120237) is down right rude! like 5" at idle. you dont have the "engine" to support it.

No. The 509 camshaft is for drag racing and moderate competition. It's a hydraulic cam but it's specs are 292 / 292 Duration - 509 / 509 Lift. This cam will not work well in a stock motor. You need to increase your compression, add an aftermarket HP intake and headers at a minimum. The 5 inches of vacuum mentioned won't allow you to run some power accessories like power brakes without using a vacuum pump. This cam is pretty much for a street strip car. Not something you would want in a relatively heavy car like yours.

The cam I suggested is a good muscle car cam and has a nice lopy idle but at the same time will allow you to run power brakes without a vacuum pump. It's the same high performance cam that came in the 440 six pack cars.

Thanks for your help Centerline, I think I will most definitely be going with the cam you suggested after doing a little reading up on your suggestion.

Don't let valvesprings hold you back, get the cam you want with springs that will work.
