thanks jim this will be the first real test with the distributor mods. ill be pulling a 4 door chevy truck
Onan prices are nuts for a a small fuel pump, I've purchased 2 low pressure with decent volume pumps from Autozone with a price range of $45.00 to $65.00 and both work well under test.....
The $45.00 is connected to the main fuel line for priming the carb and works well, Had a Carter street/strip electric pump which could NOT draw/allow e'nuf fuel (off position) while climbing hills and would cause the engine to stumble and when turned on it would work fine.
With that cheaper Autozone electric pump installed all is well with the engine.
I believe you will be happy with the distributer mods, With the vacuum advance disconnected I hope you can reach 30º-32º mechanical advance at 3,000 RPM and remember to limit the vacuum advance to 10º or even 12º......Your going to notice a cooler running engine to boot...
