I have a buddy of mine who was offering me this purple cam for my 383. He ran it for a while in his 440 before he swapped cams and went with the larger .509 mp cam.

My car is a stock 4 speed, manual brakes, and power steering so vacuum is not an issue here. Weighs roughly 3800-4000lb and is going to be mainly a street car. The car does have the stock AC in case anyone is wondering and 3.23 gears but can bump to a 3.55 if necessary. Most of the 383 will be stock, minus the headers, performer intake, and carb. I'm going to do some head work on my stock 346's. I was looking at the XE262 comp cam but If I get a freebie cam that'll save me some money.

Specs for that hyd cam are , 284/284, .484 lift,108* cam centerline, 106* installed centerline. Bascially a good street/strip cam. You shouldn't have any problem running it with the build you are planning.

I ran one for years,, was very happy with it. and yes, I would do it again...

Just don't forget about the lifters...unless he took them out and still have them in exact order, you'll want a new set.

one year ago I was getting critics because I choosen the 474/280 cam on my 400 thinking on a driver with AC LOL ( changing pistons and TC of course ), and ppl was despiting the 284/474 on a BB ( 400/383 )

now does look thi is nice even on an AC car ( true this time is 4 speed, and that makes difference )

funny funny funny.

( of course, will wait to watch next opinions coming )

I plan on getting matching lifters if he doesn't have them (And he probably doesn't). He's one of those old guys who was a professional drag racer for dodge back in the 60's and 70's. The other guy we know built the engines for dodge and plymouth, and he likes the cam as well.

This is the other thread I found on another guy asking about the cam.

If you do decide to try the 484, I highly recommend to degree it and advance it four degrees (install at 104 intake centerline).

I'd normally pick the 474 or 272/455 for a 3.55 gear, though.

If I was you I'd tell him no thanks,and go with the comp or something close. That 284 484 unless it's the newer one likes compression and gear. I've got one in a 383 with a 3:23 and I'm sick of it. I don't have enough comp. or gear to run it,might be fine for you. It does sound great though. Just my

484 cam will be a dog w/ the 3.23's. You'd be better off w/ the summit 488 cam and it's on sale for $89 w/ lifters.

I am going to mill the heads and what not to raise compression. I will be using the #'s matching 383 block from my car. It won't see a whole lot of drag time but I want the power to put the typical ricer in his place.

My only issue is knowing how the 4 speed works with all of this cause I have no experience on that side of the house. As I said before, I am probably going to do a gear swap. I have an 8 3/4 not a dana.

I still see it listed as $109. Where did you find that price?

The 484 with the right compression and gear is just plain wicked

People can scream "It's old technology" all they want. The 484 works when the combo is right

Cool I see it in the catalog.

I'd go lunati voodoo 60302, comp XE268 or lunati voodoo 60303 with comp #911 springs.

Anyone have opinions on the .474 version?

What exactly is the right combo for the .484? Most guys I've seen are running 3.91 gears. Will it work with 346 heads?

My only concern is the torque side. 71' Roadrunners weigh roughly 3800-4000lb so that's another factor.

Didn't you already ask about these cams before with your different screen name?

Yeah roughly a year or so ago when I first got the car. Problem lately is that I haven't been able to make up my mind.

I went out and bought a 440 long block complete out of a 78 winnebago. But recently I felt that it would be better to leave the number drivetrain in the car.

The reason I'm searching into cams so much is that you really cant overcam a 440. It is easily done with a 383 so that is why i'm looking into it. Another reason is I'm torn between the MP line and Comp cams line. Both offer really good cams and designs. I just don't want to go back and do a cam swap again. I had to do it twice in my chevy and it sucks.

Plus all I got last time were all the guys bashing on MP and didn't really get any pros and cons to comp cams and MP. It was really one sided.

I hear ya. If I was doing mine over I would go with the comp xe268.

I was looking at that one or the XE262 for the extra torque. I'm also shooting for good sound too which comes from the centerline.

What are you running now Ireland?
