well it sounds like you got it, if its running it will be loud open header and hard to here small sounds like ticks and light pings. if the cam is big enough it should idle ruff but smooth out as rpms come up. hope you got it licked now good luck and enjoy new motor. just be sure to watch that oil pressure and temp really close for awhile. those two items right there can tell you allot about a problem before it becomes terminal

ok if your getting the loud backfire your 180 off most likely. pull the distributor and spin the rotor facing the opposite way it is now. if you havent already done the oil system prime now would be an ideal time.

you got me curious whether or not you got your motor running. I just got done putting my inner valve springs back in my motor. one of the burdens of breaking in a new cam when you have a dual spring set up. I readjusted the valves and it fired right up and sounded great. hope yours went as well

when I first fired mine up, the timing was way off, and it would backfire up the carb, and shoot flames out headers. Ran real rough too. Timed it real quick, then did the cam break in. And yep,its real loud. Sounds like a WWI fighter.

Well I was in fact 180 off on the distro. I just pulled it and of course the oil pump drive shaft slid out of position and now the distro wont go back in. does anyone know any ways, besides jacking the motor up and pulling the pan to get this thing back into its spot. i can pul the shaft part way out of the motor with a magnet on a radio antenna rig.

well there should be a keeper lock ring on that shaft and it shouldnt come out but they will lean in there a little and you cant get the distr. to go all the way down before you get to drastic mark the spot where you need it and begin turning it a tooth at a time and try to put it back in. i think you'll find your oil shaft is still in place. mine does that to me also. it seems it will go in on just about any tooth but the one I want. so just tru putting it back where it was and see if it goes in and if not try a few other locations before you tear into it. if its just a leaning shaft like I think just keep working with it and it will eventually line up also the bottom of your dist is just like a socket for your ratchett the corners my not be perfectly lined up try that and hopefully it will save you a major job.

WELL SHE'S alive and running well. the only prob is that during my break in the cops showed and made me shut it down and just as they did the lower radiator hose blew off, I guess I should have replaced it years ago.
So can I just put a new hose on fill the radiator up and finish up my cam break in?
AND yes this baby is LOUD with a capital L i guess I should have expected so from a motor running only headers that also has performance heads, intake, carb, set at 0 degree cam timing instead of the retarded timing etc......

How long did you shake the neighborhood before the fuzz arrived? if it was anywhere over 15 minutes I would call it close enough. If it were me I'd fill er' up n' let er' rip if less than 15 minutes, do the breakin again then change the oil to get the goobers n cam lube out of it.

I have one concern though, the oil pressure dropped after teh first few minutes from 80psi to about 60 psi, I am not sure if this is my instrumentation (one of thsoe cheap triple gauges for like $20bucks) or something else. any suggestions?

well if its a cheap gauge it may have blown the seal out of it. but your pressure should drop after annitial start up once the oil warms up. my pressure at start is about 90 to 95 then drops to around 60 to 65 and I dont have a hi volume pump those arent good on these motors unluss you put on a bigger pan. they can suck your pan dry before it can drain back to it. thats something you might want to watch especially at high rpms. but my first gauge after putting my motor in failed because it didnt go high enough to read my pressure (a cheap one) and it blew the seals in it. but 55 pounds is good pressure. but if your bottom end is all new and redone with a high volume pump I would think it would be higher. if its not new your fine but like i said I would watch that hv pump.
