i would rather sell my whole efi setup and buy an intake carb distributor and coil and call it good. i have no issues with carbs that i can think of and it seems to work for everyone else so what do i specifically need to get to make this work


motor is a 98 502
rectangle port heads
roller cam
bored .034 over
everything new and rebuilt by shop

above is all the same as gen 6 502mag

what size mechanical carb do i need

what kind of distributor would be best( with box or with out)

what kinda of intake manifold


etc!!!

My question is- why do you want to do this? The EFI in stock configuration will give you better drivability, somewhat better fuel economy, and better resale value in the long run. Unless you are going on a radical performance build where the EFI setup will not work, I would say you are going backwards. Just my 2 cents.

Best thing I did getting rid of all the MPI. But of course mine was not a mag EFI.

EFI is ok for stock setups, from there very expensive to get right with tuning the ECM with mods...pieces for EFI are high $$$ and I can tune a lot on a carb...

Really? You can get a custom tune done for under $500.

www.mefituning.com is a great source for tunes.

Got rid of my EFI. no more vapor locking for me.
