    4.3 pics of a 2 bbl to a 4 bbl

    My thanks to the folks on this site, I have begun swapping out the old 2 bbl rochester to a 4 bbl Merc Weber/carter Edelbrock carb 9600. The reason for the swap was oil mixing in the antifreeze. There was a leak in the intake manifold gasket. I figured this would be a good time to add a few...

    4.3L OMC 1989 Dwell and gap dilema

    4.3l OMC to SEI Conversion

    Blew threw the lower gears once again on my 1989 OMC cobra with 1.64 gears. It was bolted to my new 4.3l V6 engine. Decided to scrap it for the SEI Conversion. The biggest challenge was pulling apart the Morse gear shifter and reversing the push/pull of the shifter cable. Wasn't that bad for the...
