Sorry can't help. Points, though--whew! I'd have to change to HEI right away if that were mine. I just don't have time for all of the maintenance.

My Haynes manual tells me dwell for a V-8 is 29-31 degrees, timing it says to see the Vehicle emissions control information sticker. Mine has been unreadable for years. IIRC, my smallblock called for 4 deg. BTDC. That's by sometimes faulty memory. (currently running about 12 deg btdc)

Definitely ditch the points.

yea, no question on getting HEI. I need to get it running well, for drivability. New truck for me, so taking care of the small stuff. Not new to GM stuff, just this one was a screamin deal. thanks again. its green, ratty, but a big block 3/4 ton, no rust generally ok vehicle that Ive named "the hulk". In CA, pre-75 are key years, as they do not require smog certs anymore. so, has a few good things going for it.

That's too cheap to believe! Forget tuning up with a new cap and rotor--just buy a new distributor every 30,000 miles!
