Default 730HP 4.8l GMC truck 10.34@130.9

Got the truck out to the 1/4 since the dyno tuning.

Setup/Dyno Thread: https://ls1tech.com/forums/dynamomet...0hp-747tq.html

Passes made at 19psi/35 shot on at 5k-6300. Broke a u-joint on next pass, but will be back soon with solid 1350 joints to work towards 9s. Truck scales out at 4400 pounds.







Also it's still very much a full street truck, this was from last weekend.

Cool

That truck hauls both on and off the drag strip, very impressive.

Still in the boxes, truck seems to be running good on the stock ones so haven't went thru the trouble.

JakesPerformance, 4l80 stage 3. Things been a beast.

Little update, trucks back and new best. Looking to get me 9 sec 1/4 slip, may need more nitrous though so I switched over to a wet shot now.
