Re: Pioneer 3/8" rod bolts
Use whatever method the machinist used when he resized the rods.
If the machinist used torque and a certain lube, use torque and the same lube.
If the machinist used stretch...use stretch

Re: Pioneer 3/8" rod bolts
How sure are you of the torque spec? What lube is that torque spec calibrated for?
The best grade of ARP 3/8 bolts (235-6402) calls for 55 ft/lbs. Seems unlikely that Pioneer bolts would need...

Re: Best Shop Manuals?
Thanks for the heads-up. I had no idea.
Clearly, GM does not want to sell a vehicle to me anymore.

Re: Proportioning valve bleed tool
Yeah, I know this is an old thread.
1. That tool has NOTHING to do with the "Proportioning Valve". It's intended to lock the Safety Switch in the neutral position. The proportioning valve,...

Re: Bad shocks or wrong tire size?
You may or may not need new shocks. The shocks are not causing the scraping problem.
You almost certainly need new rear springs. The original springs are extremely prone to cracking where the...

Re: What starter should I get?
Based on how it looks, it's an aftermarket knock-off of the PG260.
I hope you got the right starter bolts to attach it.

When I wanted a starter motor, I'd go to the Treasure Yard, find one hanging on a Buick 455. Works great for 153-tooth flywheel Chevy engines, and the Big-Block Buick would have heaps and piles of...

I had it happen over, and over, and over...until I got smart enough to reinforce the gas pedal linkage rod that was bending on heavy throttle.
