My little 383 with a 671, 8:1 comp, 10 lb boost, crappy pump gas. From 2007 up to the end of July of this year I ran a BDS 8-nozzle efi top hat. IMO, the most expensive mistake I have made.

Now running dual 600 Holley supercharger carbs and liking it much better.

Coggedbelt75, what was wrong with the inj setup? I ran mech inj for over 20 yrs on my dragsters and loved it. They all were on alky. I hated going to a carb when I built the chevelle. Tried a Holley 950HP 1st, they suck, and I then went with a 850 Quick Fuel and was really impressed. Had a needle and seat problem, emailed them and 2 days later 2 needle and seats arrived in the mail with gaskets. When I go blower carbs, it'll be QF. I have a HP on a guys chevelle out here now that is giving me fits.

The only reason I chose the injection in the first place was to be different from the other blower cars in my area. It had it's good moments, but the truck never "seemed" to run like I thought it should. BDS customer support (loosely said) was NO help from day one. No one around here knew how to tune it...I sure didn't. Went to 2 different tuners that " thought" they could do it. One in Texas and the other here in Ok. It would run either pig-rich or start to lean out no matter how was doing the adjusting on the tables. Went thru 3 o2 sensors since I had it...and they are far from cheap. The ecu that came with the injection was already out dated when I received it and FAST doesn't even support it any more. Wasn't about to drop another 2 grand for an ecu upgrade so I figured it was time to let it go.

My old truck gets me around everyday, not a racer or needing every ounce of power that can be squeezed out of her. The difference is already quite noticeable. The carbs are working great pretty much right out of the box. Only thing I had to do was lower the floats a tad. Throttle is clean and crisp now. Fires with minimum cranking. At least with carbs I know what I'm doing

. I'll settle for the simplicity of the carbs over the electronics and their costly components.

If you ever need anything else, try Hampton blowers, that guy knows his stuff and he doesn't mind helping you.
