Newbie from Vancouver, WA here. First time posting but have been lurking for a while, though and also been working with Dave W as I'm lucky to live in the same town. He's burned me a "start up" chip for the build described above. More specifics:
- Vehicle: 1991 3/4 ton 4x4 suburban. Last of the "square bodies" and only one with a 4L80e tranny. Dave W had tuned it for the PO as well.
Engine that's about ready to get dropped in:
- block from a '90 3/4 ton burb, 4-bolt main.
- Eagle stroker cast crank
- bored .030 over, true 383 cubic inches
- KB pistons
- stock 5.7 rods, resized and new bolts
- vortec 062 heads, locally rebuilt
- 1.6:1 roller tip rockers
- L31 cam and full roller valve train taken from a core vortec 350
- GMPP vortec spread-bore intake
Induction:
- reman and bored 46mm TB
- 454 injectors, 70 lbs/hr (per Dave W recommendation)
- spread-bore to TBI adapter from early 454 truck
- EGR delete
Engine just about fully dressed and ready to go in, bracketry for top end accessories on GMPP intake has required some creativity. IMG_5188.jpgIMG_5183.jpgIMG_5176.jpgIMG_5186.jpg
