Re: 1969 with 700R4 and HOLLEY DOUBLE CRAPPER
No double pumpers on the street with an automatic? I better get that $100 Craigslist 850 DP off my truck before it realizes it's not supposed to work.
Maybe it works because the truck is light (5,000 pounds) or the huge stall (basically stock) or maybe it's because I did the research and put in the work to make it work right.
Holley had no control over what we are putting their carbs on so they had to set up these aftermarket carbs where they would be close to working on the intended generic application. It's up to the end user to get it right. That's why there's so many tuning parts available.
