I have bought this carb 3 times

I have one on my 1976 chevy pickup, one on a 1972 chevelle, and got the third one to put on a 79 3/4 ton 4x4 and they are fantastic. I have even removed from my daily driver and put on my demolition derby car won the derby and put back on my truck. They are well worth the money and I'm wanting to put them on every small block I own.

I received the carb and put it right away it leaked in several points thought it would seal if I tighten gaskets but no luck. Then thought I would start engine check operation other then the external leakage and car started and within 15 seconds there was fuel everywhere down the barrels I have used this carb before and was great but this time it is a pile leaking junk hopefully speedway will look into this very expensive lose thank you

Was worried about buying a carburetor online. Worried it would not perform up to my expectations. Well, I installed it on my Hobby Stock open motor for dirt racing and I couldn't be happier. This thing performs like a champ. I would buy another one for a spare, but with this quality I feel I don't need a spare.
