1979 C-10 Shop/Race Truck Build
8 years ago we bought this truck with the intention of building a shop truck we could race on Friday nights, and also get my 11 year old son involved with the build. My plan was to build a low buck truck and show my son how to use parts most would through away. Our first engine was a 327 backed by a Turbo 350 and the factory open 3.42 gear, my son learned how to build a engine on the 327, we paid 100.00 for the virgin core. I will go through the build as we built it, our goal now is to run 6.80s in the 660. Heres our plan.

Our 327 on the dyno, 11.1 compression, 462 fuelie heads, 480/240/108 SFT cam, Performer RPM intake, 750 Holley. Track performance was 13.90 @ 101 MPH going through in second gear (3.42 gear) in Colorado's thin air.

The next order of business was to build a locked rear end with 5.13 gears, so we bought another truck 12 bolt and built it cheap. Some pictures.

Known as the "Lincoln Locker" in this part of the country. Hard to keep the run out down but seem to last forever on the dirt.

Re: 1979 C-10 Shop/Race Truck Build
When the rear end was installed we went from a 13.9 to 13.4 ET at high altitude, but I still felt the truck didn't pull through low gear like it should, 1.92 60 foot, knowing the stocker trucks went 1.77 @ Denver this bothered me, although I knew they were 300 pounds lighter, but didn't have my HP. My focus turned to the driveline which is a disaster on a 79 C-10, heavy rear brakes, heavy discs up front, which only accept a heavy tire rim combination, 6 lug. So I looked at the Lamb front brake setup and decided I didn't want to spend the money and wait (wish I had) so I tried to go the LM1 Camaro front disc setup which required I believe a 1981 and newer front spindel, but could never figure out the caliper setup so I had the original style heavy front discs redrilled for a car bolt pattern. I now could get a race style front tire and rim on the truck. I still had the ultra heavy 2 piece drive shaft robbing me............................

Re: 1979 C-10 Shop/Race Truck Build
So we headed for Kearney Nebraska 2130 feet elevation 4300 DA with bad humidity and ran 12.80 @ 105 MPH but still a horrible 1.82 60 foot, still in the back of my mind a not so quick stocker truck runs 1.77 60 in Denver running 13.8s? I've got something going on here...................
1320/105 = 12.57 getting robbed Anything that can be done to hit the tires harder at this point only responds with a drastic reduction in ET-more to come. Last edited by HP HUNTER; 10-06-2023 at 10:00 AM. |
