Default "TOMBSTONE" GMC Build, Dart 427, 88mm, Pro EFI, Air Ride

Guess you would call me an LS1Tech original, although I don't post as much as I used to.

Goal is basically a really capable Pro Touring style truck, which can also scoot down the strip at times.

Build plans:

- Billy Briggs Dart SHP 427, 6-Bolt MAST 245 Heads, all the goods inside, BTR Intake with NW 102mm TB
- Forced Inductions 88mm Turbo
- Huron Speed T6 Hot side
- NCC 3000hp Air-to-Water Intercooler (bed mount)
- Rhodes 5-Gallon Water/Ice tank with Rule 3700 pump
- Custom Cold Side
- Radium 15-gallon fuel cell with triple Walbro 450 pumps (bed mounted)
- Complete Ridetech suspension with 4-link conversion
- 5-lug conversion all around
- Mini tubs
- Custom forged wheels from Schott (20 x 7 front and 20 x 14 Rear)
- Wilwood brakes all 4 corners
- Quick Performance 9-inch with 3.70 Posi and 35-spline axles
- RPM Level 5 4L80E with Console Mounted B&M shifter
- FTI Triple Disc Converter
- Pro EFI 128 ECU (stock PCM retained for some functions)
- Flex-a-Lite Alum Radiator with E-Fans
- Hydroboost conversion

Engine shipped from Billy today and the build begins this weekend. The Ridetech will be modified in the rear using their universal 4-link setup so I can move the suspension inside the frame rails to accommodate those 15-inch wide tires out back. More to come soon!

I may need to paint my intake black like that. Looks pretty good.

Looks like it's going to be an amazing build.

We have a place that does a lot of powder coating for us, so I took it down there.

LOL@ triple Walbro 450's. I thought 2 would handle 1000whp with E85. Do you need the third?

Not sure until we push the BIG BOOST button

I may run out of turbo before fuel.

Just a few things done the last 2 weeks. Moved the fuel cell over to make room for the A2W and tank. Received parts for 9-inch:
