...and I have one of those fer sale, cheep! Frank D/W Now the small flange BBD from a 273/318 will bolt directly up on the slant and run good all day. Ditto for the Stromberg WW3 (from a poly 318) and in some cases, the Holley 2280 from later 318s. Im running an old Stromberg WW3 on my slant and runs like melted ice cream on a sunny Miami day in July.

I avoid the holley 2280 at all costs. they use that vacuum power piston that seems to fail routinely....every one ive had i end up trashing because that wretched power piston wouldnt hold vacuum and they are not found in any zip kit for the carb

I have had both the 390 holley and 500 holley on my car. I sold both. The 390 ran well for it being a stock to mild engine. I installed this after the 500 2bbl, reason being was cuz the performance wasnt there, she did give me about 16mpg but she leaked and backfired, I had the set screw in for the power valve block off, but something was always wrong. The 390 when I dynoed it, the secondaries werent opening, apparent vaccuum leak on the diaphram. I replaced the diaphram and the correct spring and the engine only gave out 101hp to the rear wheels, Which I find very strange. I have since replaced it with an Eddy 500 4bbl, havent done the dyno yet, but i still pull 16mpg and run with stout small blocks. |

I have been considering upgrading my 225 with a Holley 390 and a set of headers. My 73 Dart is my daily driver and I'm wondering how the kickdown linkage to the auto tranny would hook up. Is it an easy enough swap?, or am I better off staying with the original carb. Also I've read that most header set ups have clearence problems. How does one purchase Mr Dutra's setup? I have two extra exhaust manifolds that I can use. It would seem as though this is the better way to go. Al in Ct. |
