Axle upside down?

April 20, 2018, 10:05:16 PM by ken4444 | Views: 32 | Comments: 1

My C10 has a spring-under conversion. I happened to notice the casting numbers on the differential housing are upside down. What's the likely story here? Is this legit, a total hack, or something in between? I'm thinking it doesn't matter from a mechanical perspective, but my experience here is minimal.

Header question

April 20, 2018, 07:54:06 PM by square81 | Views: 35 | Comments: 3

I have a chance to buy a set of ceramic coated headers for my 1981 gmc seirra 2wd with a 350. The part #69830 elite series from hedman. Says they fit 4x4 trucks, but would they fit 2wd or are they just for 4x4. Not sure on the differences. Pipe length and design possibly. Anybody ever ran into this. Thanks in advance

External coolant bypass vortec head's & block

Vortec head specific question. I started to look into the plumbing for my build, specifically external coolant bypass. The vortec head's don't have a hole like most 1st Gen head's have that allow coolant to bypass internally. My new intake (edelbrock7116) has provisions for an external bypass and it says to go from the intake to a opening on the passenger side if the vortec water pump . Now I'm not running a vortec water pump l, I am running a clockwise rotation water pump. Does anyone have experience on where I run my hose from the intake? Pics preferably.

84 C10 Tranny Swap

April 20, 2018, 12:20:13 PM by Ronno6 | Views: 33 | Comments: 2

Someday, if I EVER receive any ordered parts, I will be dropping the TH350 out
of my C10 in order to replace with a Muncie M20 car transmission.
When I replace the flex plate with a flywheel, can I reuse the crankshaft bolts
or do I need different ones?
I see flywheel bolts for sale, and I see flex plate bolts for sale.
I see 7/16-20 thread descriptions everywhere, but never any lengths.....
