Most big blocks I've had like it advanced. I wouldn't use the +4 deg slot without putting a degree wheel on it. Most cam's have some advance ground into them.

Your input is appreciated.
Being that you didnt degree it in the beginning you dont know where its installed at... just by moving the crank gear you are still not sure where it is.. you have to put measuring equipment on to verify what you have

How much you will gain can be a whole bunch if the cam was off a whole tooth like in a car I bought many years ago. I picked up over a second in the 1/4 Your results may very Odds are the gains you see may be small, but you never know. If a cam is the wrong duration on one side or the other, it might be a wash. If the cam is a perfect match, it could be worth a lot to get it in at the perfect point for the combo.

I believe they advise to install it on a 108 centerline. When I ran that cam in a mild 383 I had it in on a 104 centerline and it seemed to run good. It was my old Dart street car that had a stock bottom end 383 with 9.5 comp using 452 heads that we did some bowl blending. Of course the .484 cam with stock rockers and the usual bolt on's like RPM intake and 750 DP. Also had headers , a 10" Tutrb Action converter and 3.91 gears as it ran a best of 12.31 @ 110. Ron
That is a good running combo. Mine only runs 12.70's @ 103-104mph. I think I want to degree the cam so i know where it is at , then i will start tuning the carb, which i have never touched either. looks like i have a lot to learn

Thank you. I always degree my cams in my hotrods because if you dont you really dont know where the cam is at. I have seen some as much as 10 degrees off which is either in the cam or the timing gears. So as long as you degree it you know where your at. I would definetly go into it and degreee the cam and then you will know where its at. That way if it does not run up to par you will know where the cam is and if you want to change it. Good luck , Ron

Welcome to the "automatically advance it 4 degrees" web sight - after you find out where you are at to start with.
I DIDNT advance the cam in my 416.. its a 105 LSA and I installed it at 105... didnt want to add to the torque to stall the conv higher.. its 5000 already being on the street

Same here as I put that 383 together before I even had a computer. I always like to advance my cams a bit in my street cars. That just happen to come out at 104 with the offset bushing I used first. Ron

The real question is how much power can you lose by NOT degreeing the cam, especially in a big C.I. stroker with a Mopar brand cam, the answer is a lot The first solid roller cam I installed happen to be ground with 8 degrees retard built into the cam keyway That turd wouldn't fall out of a tree with elephant pulling on it In all seriusness it was horrible retarded that far Once I learned how to find the lobe seperation angle I started degreeing all the new cams I used and installed Later on I had a custom ground cam that was not ground as it was suppose to be, the cam company switch the exhaust lobes to a different lobe number and forgot to read the custom order instructions, I now install the cam based on the intake lobe centers and I always check the exhaust lobe centers before deciding to use the cam or not Cam companys have employees who work for them, most people make mistakes sometimes in there life Murphy loves me, he messes with me all the time Better to take the time to check first before finding out later it was ground or marked wrong on the box and cam card
I hope I can find a lot of horsepower. My dad had this same engine in his road runner with a .509 cam and it felt like it had a good 100hp more than it does now.
