There is another cam currently listed with dodge

P4452808 .410/.425 110 centerline

But I do have a question. What is the specs for the original cam. I have been told that it is part # 4448304. The local dodge shop could give me the number but no specs on it. I would like to see how the aftermarket cams compair to the original.

Your right Gus, that was another cam for preMag 3.9's, I didnt list it and a couple of others because they were lower performance.
All part #'s I listed including the one you listed are not in the current Mopar Performance catalog, and the last one I listed is in the "discontinued" section in the back.
The only reason I listed them is because sometimes wharehouses and distributors will have disco'd parts sitting around and I have found sometimes if people walk back and look instead of believing there computers they have disco'd parts sitting around.

Sorry but I have no idea what the stock specs are, I would think VERY mild and would guess a 108 or even a 106 centerline.

Good luck, Scott

Hi Fazdak! Just wondering if you ahve a few names of parts stores/warehouses where I might be able to find the P4452747 heads for my 1990 Dak? I live in British Columbia, Canada but if I could find a good deal on these heads, I would consider shipping them to me. Mancini Racing has them on back order at $1500 US/pr but that equates to ~ $2500 Cdn. or $80/hp if 30 hp gain is possible.

Any info would be greatly appreciated-I have been talking to a few other regular forum users who have suggested porting/polishing heads + install of new cam is another option if I cannot find the above heads. I do to want to peel the tires off my truck but need help when I tow a 1500 lb trailer(my previous post is titled "magnum heads on pre-mag block on pg 43 of the V6 forum).

I own a 93 ram with the 3.9 and i cannot for the life of me fine a good cam without getting one custom made. i would like to know if there are any current made cams for it and any other performance parts. i was thinking about going and custom making a twin turbo setup for it off of a few junkyard cars. how much hp do u think we are talking. factory spec 180hp, 225ft lbs.

Allen, if you add a turbo, or two, you will need to add a little more fuel as well, or it could melt the pistons.
Good Luck
