1979 C-10 Shop/Race Truck Build

HP HUNTER · 10-10-2023, 10:01 AM

So we moved to Texas, I ran the truck @ 450 feet elevation, 2000 DA with the 327 which resulted in a 12.13 @ 107+ with a 1.63 60. at this point I knew the truck would never run 11s in the heat so I decided to build a 350 hoping this would put it into the 11s. Notice my ET @ Kearney 2130 feet 12.80 dropped to 12.13/7.63 @ Little River 450 feet. My drive line losses were showing what every bit of extra power was worth.

1320/107.5 = 12.27 much better at this point, but far from done..........

Are you doing dyno work in Texas? Little River has a lot of history.

Just a brainstorm about the truck project. You could fine a short bed and convert the truck to a shorter wheelbase with a one-piece driveshaft.

We almost bought Larry Hills stocker truck, and then I would have had a mid 10 sec truck, it was my wife's idea, but I was worried about getting it emmisioned for street use, because we drive this truck a lot. And actually I like my own truck. We were going to get it shortened and the shop that was going to do the work was getting flaky, and was worried about the chassis being square, but that's definitely

a option if I can find someone I trust.

Yes-we dyno test.

So I started my 350 build, .060 over 2 bolt 010 block, I did some work to the factory cast crank which ended up @ 3.483 stroke, I put a 6 inch rod in there with a + 6 cc dome Mahle piston, my Fuelie heads came in at 74 CCs which gave 10.8 compression. My solid lifter cam was .528 lift @ the valve with 264 @ .050 duration on both sides, 108 lobe separation. I used a Performer RPM intake with a 750 Holley, the Moroso pan was modified.
