484 and 509 cams run like raped apes when degreed and set up properly. They were and are really hard to beat problem I found is they are more often than not actually retarded dot to dot from the recommended 106 install and 3 to 5 deg advanced from where you regularly find them makes them respond in amazing fashion. Found a 509 once in at 108.25 advanced it to 103.5 and wow guy could not believe the change already had a 3000 stall and I had told him he would not need a 4000! Just did a 509 in a 383 new Mancini timing set dot to dot it was in at wait for it......... 114 wow. That's 7.5 retarded form recommended install and 10 to 12 back from where I would like to have gone. then at the 4 advance keyway put it at 106.5 thats close tried it a dozen ways including another new gear set the same all numbers came out the same and since it had a slot in the top gear could not drill and use offset bushing. It will be fine at 106.5 (4 speed 4.56 gear) 103 would have been better and 114 woul have sucked pig time and may even have hit exhaust valves!

First I want to thank everyone for all the replies. I know my new cam probably isn't the best for my combo but I did a lot of research on the internet and basically found some people loved them, and some people hated them. I also read several posts on-line of guys with virtually the same set-up I have running mid 12's with that cam. I can say now from 1st hand experience that that 484 cam I have in there now is just a tad lazier at the bottom than the Comp 268 that was in there, but I think a higher stall converter will help that out a lot. I can also say that from around 2500 rpm up, the 484 pulls harder than my 268. I mean it actually snapped my neck back. I wasn't expecting that! And with my 4.10 gears I'm right at that RPM frequently on the street. I'm going to start tweaking the carb (need new power valve I'm sure) and then get a higher stall, and see how she responds before I start tearing into the motor again. Although I gotta say I would like to learn to degree a cam.
Also, when I adjusted the timing this is what happened. I advanced the dizzy clockwise as far as it would turn and still couldn't get enough advance (could only get to 0 degrees). So I changed the wire positions, moving each one over clockwise one terminal on the cap and adjusted timing. I think that the dizzy was reinstalled one tooth off (in this case retarded). As far as the timing tape being removed, I have no idea why. And the reason I am going to replace it is because the timing tab doesn't go that high and I like setting my total first and then inital.

If the shop installed the intermediate shaft a tooth off it would, in effect, make the distributor a tooth off.

I just got a call from the owner of the shop and and e-mail from his wife (who works there too). The said they were extremely shocked and embarrassed by what had happened. They said the guy who worked on my car was fired as of today and that they will come and pick up my car at my house and trailer it to the shop, take everything apart and check it all out, degree the cam and install at 104 ICL like I want, tune it and time it and stated "I will not let that car out of my shop until it runs perfect"---all at no charge. The owner really sounded sincere and apologetic. I think I will let them take it back and see what they can do. Again, many people in my area take their cars there and couldn't believe what happened to me. I will keep you all posted as to what happens.
I would have them pull the intake too, and to check the cam/lifters. if they fired the guy because he didn't know what he was doing, you gotta wonder if he broke in the cam properly, with 20 minutes at 2000 rpm to establish a wear pattern for the lifters to the lobes. if that never happened, you could be eating away cam lobes right now, and could be just a few short miles away from requiring a full engine rebuild from all the metal that ends up in the oil and through the entire engine.

I think they will too. I was at the shop today and they were very apologetic and had me write down everything I wanted done and they would do it one by one. I did verify a vacuum leak at the intake manifold at both intake ports on the passenger side. When I sprayed brake cleaner there the idle slowed down quite a bit. And yes, the guy re-used the old valley pan gasket with minimal sealer that I could see. So I told the shop to use a new one. I also told them to degree the cam and install it 104. I gotta say though, even the way that cam is in there now, the car flat out carries the mail!!!! It pulls hard and noticeably more than the 268. I know a lot of people don't like those 484 cams, but damn, it sure seems to work well in my application! I'm hoping even better with it degreed and advanced.

Will bee interesting to read your posts on the difference between straight up and degreed once it's done. Will like to hear your report on what you think. Been running mine straight up for fifteen years. Wouldn't change a thing
