With the help of a good friend I now own a wrecked 1989 1 Ton 2wd crew cab that I bought for $850. It has a running 454 TBI, 4 speed manual tranny and the Dana 70 dually rear end. Assuming the rear ratio is 4.10, I have the rear end sold to a buddy for a bargain cause he has helped me so much on my truck. With the rear axle sold the purchase price for the truck drops to $600 and I might have the tranny sold also so before I know it I might have the final purchase price down to around $400. Kinda lucked out. I'm gonna swap the 454 into my 69 K20 after yanking off the TBI and replacing it with an Eldebrock Performer intake and carb and probably a slightly hotter cam. Should be a fun swap. Anyone done a similar swap with recommendations on what to expect?
