Well this sucks TBI down

The TBI motor I built a few years ago has some severe health issues. The piston married the exhaust valve. Match made in heaven but the pushrod was bent out of shape. Cam gagged on the lifter and puked it out. Fun puns aside it’s a can of bees being kicked around. Head is junk, cracked...

Frame question

Working on a 95 gmc suburban 1500 4x4. Rear frame rails went to hell but otherwise truck is in really good shape. Question is, I’m looking to graft the rear frame from a southern truck, is there a difference on the back half of the frames from a 2wd to a 4x4?

Mufflers - choices choices......

Time to pick out some muffs for “dad’s truck”. For those that don’t know, it’s a 90 k1500, 350 tbi injected roller cammed, 300hp beast. Made the downpipes and am test fitting different muffs to see what sounds the best.....down to a choice of super 10 flowmasters or magnaflow.

Dad’s truck

So I’ve been in the process since November of fixing my father in laws truck. (Since then he’s been through hell, and currently facing life threatening liver issues. If I don’t get a hitch in my step it very well may end up a tribute truck:(but that’s not the point of this story.) He had bought...

Clutch hydraulics/parts

Have a 1990 k1500, while the engine is out new clutch and what it going in. My question is I can get all of the hydraulic parts (master - hose - slave) individually for the 1990 but if you jump up a year or two there is a complete prefilled prebled assembly. As I have not had much luck with...

Alternator wiring question

Hey guys, I've just picked up a 95 k1500, while cleaning up under the hood, I noticed the yellow wire coming from the plug on the alt has been cut off near the battery/pass fender. I can't locate the other half. Does anybody know what or where that wire goes to?
