Yet another GMC build

Hydroboost is awesome.

hydroboost feels different for sure ... but it's like putting an 6-71 blower on your brake booster! having the stopping power of a rig built to drive around at 12,000gvw, but only rolling 4000, works out reeaaalll nice

AND, its the same all the time unless the engine dies or you blow a hydraulic hose, then you have one boosted brake application before the manual brake feel comes back.

I was car 454 at the track today. Wanted to see how it went with a new set of drag radials on the rear. Best time was 11.7 and I am happy about that.

NICE!! hard to complain about a solid 11sec truck!

having issues anywhere, or anything you'd change to try for faster?

Could go with a stall converter but the radials might not hold anymore. Could also try more timing or boost with E85 but I like running pump gas and also drag radials might not hold. It would either hook or spin a half turn and go. Just about perfect. The Nittos are expensive but work. Plus, because the tech guy passed me without even looking under hood, I was later warned that if I get faster than 11.5 they will require a roll bar installed. Not sure I want that. Yet. Still would like to make it work on a road course. But I need more brakes, lower in the rear which means frame mods, and track tires. How cool would it be to go track with a bunch of Corvettes and BMWs in an ancient pickup truck?

ooooo, i always forget that 11.5 is the breakover ... 11.7 is fawkin MINT!

the cornering game can be a deep hole too. moving weight, alignment adjustments, getting springs/shocks/bars tuned just right. worth it.

Thats awsome. I live down the road from New England dragway. Hoping to run mine down the track next year.
