8ba to Front Mount Distributor Question
A friend is installing an 8ba in a '31 pickup and doesn't want to cut the firewall and will run stock hood. Water pumps are set up for one narrow v-belt drive, has the two bolt distributor front cover and '48 type cam and gear. What is the most compact distributor that might fit this application? The crankshaft pulley has the outer belt groove removed and is 6" diameter. All help is appreciated. He will be using a 12v alternator.

Re: 8ba to Front Mount Distributor Question
I'd say the 42 thru 48 crab type. Most others protrude farther forward and the crab is very adaptable.

Re: 8ba to Front Mount Distributor Question
After reading your magic "link" Bruce it looks like he will need the 21a unless the 59a can be modified to accept the 21a crab cap. Now if Bubba can chime in and says he can install electronic internals all we would need is to find a donor distributor. Thanks for the information fellas, appreciated.

Re: 8ba to Front Mount Distributor Question
I did a web article on my conversion to electronic internals for the crab distributor; here is a link:
http://mysite.ncnetwork.net/wgmumaw/...rsionBills.htm Electronic internals is not really correct for what I did though,there's not much electronics in the distributor, basically a "trigger generator" for the remote mounted HEI module that contains the electronics. The conversion is a lot of work as the Mopar parts I used are a little large to fit in the distributor without some mods. One of these days I plan on doing a project using an HEI module triggered by points. |

Re: 8ba to Front Mount Distributor Question
Thanks Bill, great job you done on it, appreciate the link and very nice craftsmanship, drawing and pictures. Do you have a picture after installing the HEI module?

Re: 8ba to Front Mount Distributor Question
The 59A can be converted to the crab cap by installing the hold down clips and using the 21A rotor which is different than the 59A.

Re: 8ba to Front Mount Distributor Question
Is your friend using the 59A crank pulley at water pump pulleys or is he using the 8BA crank and water pump pulleys? The earlier pulleys are a lot closer to the block and take up a lot less space at the front of the motor.

No, sorry. I had the module mounted under the dash at first and had one fail so I moved it to the front of the intake attached to a bracket that holds the coil also. A future project is to make a little finned aluminum box for it. |

Re: 8ba to Front Mount Distributor Question
I have the same setup on my 30 pickup. A 8ba with a 2 bolt cover and 59ab heads. I bought a daul point Mallory from Speedway. I have pickup water pumps [ long ] with double pulleys and wide belts. I had to shorten the fan snout to clear the rad. I don't run a hood but this setup would clear.

Thanks Jim and all who responded, appreciated. He is in the process of buying a 21a distributor and if everything is okay then go to electronic pickup instead of points. Vergil

Re: 8ba to Front Mount Distributor Question
The 59 series crank pulley sits closer to the engine than the 8BA. You will gain an appreciable amount by swapping to the earlier pulley.

Using 8ba narrow pulleys, one belt (using two drivers side pulleys on pumps) with front groove on crank pulley machined off. I am using the same setup but no distributor (crank trigger ignition) to worry about, added another pulley on the fan to drive alternator, picture below but not a very good one. Fits in and didn't have to cut the firewall and running hood. Vergil
