Thanks that reminded me to try the different pump shots for the carb and see what happens. the thing runs like a bat out of hell now!

This may be a good opportunity for you to teach your son how to determine top dead center so that he can time the motor properly with a light.

As soon as the engine will tolerate without detonation. 2500-3000 rpm is a good point to shoot for, but if this is a heavy truck with big tires and not deeply geared it may have to be higher.

In this type of case, you'll be depending on the vacuum advance to provide you w/advance under light load and throttle settings. If you rely solely on the mechanical advance, you'll never have enough timing to allow for economical cruising.

BTW, if your tires are right at 30" to 30-1/2" tall, you're at about a 3.42 ratio running 2100 RPM @ 55. MPH.

Yes, unless you get lucky and the OEM unit has the right amount of advance built into it.

If you want to try a different advance can- and you have an HEI ignition- there are at least two that are readily available.

ADJUSTABLE VACUUM ADVANCE CAN KIT- Crane #99600-1, 99600-1 INSTRUCTIONS.

And the ACCEL #31035 is an adjustable vacuum advance can for GM HEI that allows infinite adjustment to BOTH the amount and rate of advance. Comes w/instructions and tool.

DETERMINING TDC will allow you to be sure the timing tab and damper are correct for TDC.

MAKE A TIMING TAPE to see what the total timing is, w/o needing to use a dial back timing light. Or buy one.

okay so i was not able to pick up the curve kit the other day. no one around me carries it and so i will have to order it off of summit of jegs. i noticed today after we got the exhaust installed (now it's quieter and you notice more) that when you raise the rpms up to 3000 and hold it for a few seconds it seems like it pops pretty good. i don't know if it's just the sound of the headers though. it's almost like it's missing if i think about it.

it sounds like we are having a similar problem. I installed a fuel pressure regulator and set it at 6psi (was around 10) set my timing at 14 deg btdc and that solved a good bit of my problem. I also changed my header gaskets and it solved my exhaust problem with popping. mine was when i accelerated then let off the gas though, not sure if that was the case for you.the only problem i have now tho is when i punch it it loads for a sec then takes off. have u checked what your fuel pressure is at? electric or mechanical pump?
