truck weighs 4500 pounds - just cruising it on the highway.
i'd like to think it is the crappy alcohol blended fuel, non-hardened seats and no lead additives is what burned up the 906 heads.
UPDATE -
i think i have figured out the root of my problems. it appears the springs on the mechanical advance in the distributor have stretched out. last time i messed with the timing on the truck i set total advance at 36 degrees with initial being around 8 or 9.
when i went to check total advance last night it had worked itself on up to 42 degrees! i backed it up to 36 total degrees and then idled it down and initial timing is now reading 6 degrees.
does a 30 degree curve seem a bit unreasonable for a fairly stock engine?
anyone know of a good resource to get a rebuild kit for an original dual point distributor converted to pertronix? i think i need to narrow down the distributor curve a bit because it is a bit gutless off the line - we can't have that now!
Thanks MOPARTS!
