- Vortec 383, modified TBI/4L80e
This adapter allows use of stock (or modified) GM TBI on a spread bore or q-jet manifold. I bought it for my vortec 383 but I ended up using the adapter that GM used on the early 454 TBI. The GM one is taller and has a vacuum port that I needed. But this is a well machined unit that I would definitely have had no problem using. Tons of them on ebay, most around $50 or higher. I'll go $20 + shipping.
