slightly used holley 4150 750 hp, couple of cruise weekends on it. it is back in the box. I have an aeromotive 1 -8 in 2 -6 out style regulator, polished billet and 1/8'' port for gauge. also have a billet csr throttle cable bracket. I might have some fittings for the inlet bowls too. the carbs are pullin like 400 on ebay, the reg was maybe 75 and the brkt was maybe 50. I was thinking 450 for everything. please just pm if interested. I would prolly throw a couple of gaskets on the carb it has been sitting for almost a year, it was drained tho. also it is square jetted and ran awesome!
