1994 Cheyenne (Super) project truck

[GrannyNova]

I have started doing local autocrossing last September in my 1994 Cheyenne pickup that has done ok against a 99 Silverado with a v8, slammed, and 22 in wheels, but I am looking to take the truck to the next level the coming years with upgrades to the V6, a manual swap, brakes, more suspension upgrades, and rearend upgrades.

Only a few upgrades have been made to it already with DJM 2in front drop springs, 2in rear drop shackles, 17x9in Black Rock steel wheels with Riken 275/40-17ZR tires, and a big aluminum radiator and one real upgrade to the motor in the form of a MSD coil and wires.

Sounds fun! Are you planning to keep the v6? Good luck with the build!

Yeah, the v6 will make the power I need plus way lighter than a 350 once I get some Brodix heads.

4.3? If so they're great little motors. Lighten it up, make it handle and go beat the snot out of it! Sounds fun.

Yep and the original one to it with its 301,000 miles it's a little wore out right now, but I got plans for it.

Added a electric fan add and wired in with Derale controller and deleted the mechanical fan.

Ended up fabricating a exhaust cutout on the factory crossmember with some 6in wide 3/16th thick plate steel and it's made sideways because the floor is at an angle in that spot.

Maybe later down the road I'll do the next one in a tubular fashion to lose some weight.

Not much stiffness to that box. I would recommend gusseting it in the corners (while still allowing enough clearance for the exhaust). You could also possibly support it on the outside of the box. Either way you need more stiffness if that is really the transmission x-member.

It flexes a little with a 1in gussets on the corners, we'll see what it does with weight on it before I add more supports.

Dropped the engine and trans and the crossmember fit perfectly except for one of the bolt holes doesn't match the frame anymore but that's only minor and the crossmember had little to no flex when the weight was dropped but had a new development accure when we tried to put in the stock driveshaft, so we'll have to get a new one made and possibly go to 1350 yokes.
