    Do I rebuild my SBC or swap for an LS3?

    Warning: Long. It was a long fight for 2 years? Learned a lot. Hated the truck and engine for a long time. Still kinda do... I thought my HT383 crate engine with vortec heads was going to be the perfect engine for me based on all the reading and research I did. Turns out everything I read was...

    What made you decide on 20s instead of a 17 or 18?

    Ol’ Bonnie looks kinda silly now…

    Throw 2,000 lbs of gravel in the bed and complete the look with some "free" squat! :Big Laugh:

    400 SBC Build

    Vortec heads removed the heat passage/plenum that used to go under the intake manifold. This isn't needed nor wanted when you have multi port fuel injection. However- if you don't have multiport injection you get a very cold intake manifold in winter. So cold that fuel can and will drop out of...

    Poll: What '70s/'80s pickup would you own if a GM square wasn't an option?

    My parents had Wagoneers growing up. A '72 and a '78. They were ok- always like the Cherokee Chief better. Neighbors had one. My uncle had one of these:

    Vortec heads spark plugs and dieseling

    Not sure if this helps or not but on the GM crate engine I bought with vortec heads (HT383) they said to set timing to 10 degrees BTDC at 650 RPM with the vacuum advance line to the distributor disconnected and plugged. They want 32 degrees of total advance when using HEI distributor P/N...

    k10 drag link steering question

    I keep seeing posts all the time saying the drag link has to be level. This is only true on a stock height truck. You actually want to try and match the curve of the leaf spring. The stock springs were flat or a negative arch. So the drag link was flat. It deals with how the axle moves when you...

    Holley Sniper and Gas Tank Swap

    Axles travel rearward when compressing. The leaf spring is attached at a fixed point at the front side of the leaf. Can't move forward. As the leaf flattens out it grows "longer". The shackle moves rearward and the axle shifts to the rear a bit in response. But I get what you are saying now...

    Picture Please: No Spare Tire Holder

    Spare tire holders can be under the bed, or in the bed. Which are you looking for? Mine was upright in the bed right behind the driver.

    89-91 LMC headlight upgrade

    My fingers work better when they aren't cold- but you do have a bit warmer temps over there. It would be ideal to pick a nice 65-70 degree day...

    89-91 LMC headlight upgrade

    I have the glass Hella 7" round headlight housings. They take the H4 bulb... But you were almost right with the LMC idea- I did buy the LMC headlight relay wiring kit.

    How to achieve tighter steering?

    And even if the frame isn't cracked it is still flexing. ORD sells braces that help strengthen and reinforce the frame up there. https://www.offroaddesign.com/steering/steering-box-braces-frame-repair.html

    Holley Sniper and Gas Tank Swap

    Wow- so even with a 4" lift you think the rear differential will hit the fuel tank? I haven't heard this was a possibility. And what would happen if there was a 14 bolt back there... even worse then, right?

    Holley Sniper and Gas Tank Swap

    Tracking this- as I want to do the same thing. Someday. Is your truck a shortbed? Would there be any advantage to using bedliner on the outside of the gas tank? To help protect it from getting a hole rubbed thru it by the straps? Maybe even a "real" one like LineX?

    Leaf spring and other suspension questions

    Maybe it depends on the year. My '77 K20 had 52" springs. When I bought new rear springs I switched to 56" with ORD's shackle flip. I have about the same load carrying capability but it did make it ride a bit better on the rear end.

    New Method 701 racing wheels

    I was looking at those for quite a while as I was mainly interested in their "bead grip" as I air down a lot. Looks good.

    Torq Locker

    Does the manufacturer recommend synthetic oil? Some don't for whatever reason. That being said I like Amsoil severe gear. I've used the 75w-90 but I've read a lot of guys that live in a hot climate run 75w-140.

    Speedometer cable service - how to

    My speedometer has been bouncing for years.... I'm sure a dumb question- but you can't take the cable out from the transfer case end?

    Driveshaft options for 1991 r3500 4wd conversion

    It all depends on where you live. For me there is basically just one shop in town for drivelines. Been here forever. I've heard the guy was a jerk. I drove to the shop and asked him about driveline modifications I needed and he just laughed. "For something like that just go to a junkyard. I'm...

    Is the 8.1 still a dead end swap?

    Is the 8.1 still a dead end swap?

    I had a 2003 Silverado 2500HD. Extended cab, long bed, 4x4 with the 8.1L. I kept hearing how bad gas mileage was- but it was from the Allison transmission equipped guys. Mine had the ZF-6 manual transmission. It made them a lot more efficient, and better power to the wheels. I use Fuelly and...

    FOUND IT! '86 K5, 2 1/2" Jacked Front, Rear Stock Height ... etc.....

    Do you have a drop pitman arm? If the road is perfectly smooth is driving ok? And only once there are some dips and bumps then it starts to pull/wander? Might just have bumpsteer.
