the cloyes timming set you used has a 3-way crank sprocket, it has 3 keyways on sets the cam centerline at TDC one sets it 4 degr. adv. and one sets it 4 degr. retarded. i'd almost bet you installed it retarded. the distributor you have is fine with a recure kit and the advance all in by 2500-3000 rpms, keep in mind while the billit stuff looks cool, it dont put you on the other end of the track.

Just a note you may think about getting the rearend done first. It may wake up the engine/cam to make it perform as it should. IF you are not going with a junkyard 3.55 axle as their all over the place and plan to just install gears in your 9 inch I believe is what you have and mpg is no concern then I would opt for 3.73 or 4.10. If you are not happy after that then you probably if no other things are wrong with your tranny or engine need a different cam. Reason I mention doing the rear first is when you order a cam they are somewhat specific to your rearend and if you plan on a lower gear (numerically higher) then you may want to do that first or it may throw it off when you do. Call a manufacturer of your choice and give them all your specs and you should be happy with what they recommend. More than one person around here and other sites are happy with the comp cams, or crane. Good luck

that cam according the specs you gave us, should be a excelnt low end cam, you obviously have a problem somewhere, was the cam properly broken in? you need to find the root of the problem b4 waisting money to fix somthing your not shure is broke, going fast and making power is not the action of one thing, its a combination of things that HAVE TO WORK TOGETHER.

well here are the things that are wrong with the truck that are taken some power away. i have tried everything and the alternator still does not work i had it tested and replaced the voltage reg., adjust timing back some adjust carb i am going to take it to somebodies house so that we can both fix all of that. how do you break the cam in. before i started driving it, for a couple of weeks i cranked it up and let it run while i tinker with the engine. does that count as breaking it in?

Thats why I mentioned that in my previous post. Everyone including myself have looked up your cam and confirmed it is more likely than not an rv/torque cam by the specs you gave. However, my theory on you rearend being too high could very well be a fair reason why your not happy, if the cam is not able to operate as it was intended/ if it was designed for a lower gearing. Oh well, maybe you will figure it out when you and your buddy mess with it, probably just something simple. Good luck

If you didn't break it in according to spec, you probably wiped a lobe off the cam. If you really don't get it going immediately for 15-20 minutes, you'll make the cam face and lifter grind each other down to nothing in minutes. You don't make enough oil pressure at idle to prevent wear from occuring, and if your pressure isn't very high to begin with, it could happen anyway.

is 65 psi enough pressure at idle. it makes almost 80 cruising. if the lobes are ground down would it run rough and not run good. i want to get 3.50 gears what rearend gears should i use.i want good take off with the cam i have and for daily usage. how about some timing advance springs would that make it run better with the cam

anything over 40psi at 2000 rpm, mine runs 42-45 above 2000 rpm and it is new with a new stock pump.
You should figure out your cam condition first get someone to put a dial indicator on your rockers and see if the lift is okay. Then go from there. If you go to 3.50 gears you might as well go 3.70 or 4.11 there is only a few rpm difference there. Check out your cam first and make sure everything is sound engine wise. Good luck
