I just built a 383 stroker. It's now in an '88 Chevy Blazer 4x4. It had a stock 350. I bought a tbi from a friend. The ports are bigger on the new tbi then the stock one. I need to bolt it to the stock intake. I have a tbi spacer with the stock tbi port size. Is there an adapter that will funnel the port from the large port tbi to the small port intake?
