A couple years ago I went through my truck. This is an extension of dialing it in. The truck was stock with 60,000 miles except the previous owner had swapped in a 327 in place of the 6.2 and 3.73 gears in the D60 and 14ff.
At that time, I stripped the truck down and refinished items such as the chassis, stock 1-1/4 ton leafs, axles, and various other components. I put a new GM L31-R Vortec, Holley Sniper EFI with Dual Sync distributor controlling timing and a bunch of other boring restoration items.
Fast forward, I am looking to try some different stuff. For one, the springs are not so great without a load. I ordered a 3” ORD custom spring setup, longer shackles(not flipped), Bilstein 5100(5125) shocks which are supposed to be here the end of the month.
I’m also currently swapping in an NV4500 and rebuilding my 208 after finding a defect in the input seal. I don’t want the ATF in the 208 killing my nv4500.
Additionally, I’m trying Edelbrock’s new pro flo 4.
I’m also a member of GMSB and appreciate all the sources of input and help I can get. Thanks in advance!
