I've had my '74 Bronco since 1987 and have had a couple of healthy 302s with a few different fuel systems over the years.
Started with the stock 2bbl to an Edelbrock Performer on an early Mustang intake (ran great on road, terrible off road) from there I went to a Holley Pro Jection (ran great but, would flood after a hot start) to the present Qjet on my 351W which works pretty good off road but, drains the float bowl overnight, making cold starts a real pain and mileage sucks, too.
I have a complete GM TBI conversion with custom harness and prom for my engine specs: approx 9:1 comp and Edelbrock Performer cam (my truck is plumbed with fuel return lines from the Projection system and I was planning on using the Projection pumps).....whew!
I came across a rebuilt 4100 with smaller 1.08" venturis on eBay for about $300 and am rethinking the TBI.....opinions.
