been thinking of building a modifed, i have complete model a chasis with all stock stuff , and just acquired an 8ba flathead. my question is will the model a banjo rear (28 to 31) survive behind and stock 8ba with a super dual intake and headers? just trying to get all my ducks in a row before i start in on this project.
That is a good question. Some will say no way in hell will it survive. And others will say yes, providing you drive like my Grandma. Well, My old model A (1930) with an A axle had an 8BA in it and was like that for ever. It was built that way, I drove it for 5 years and never had a problem with it. But then again, I am not one to dump the clutch or drive aggressively, I did however spin the tires in the loose stuff and it survived. I must have put 8,000 miles on that car in the 5 years I owned it. I frequently drove that car 70 MPH for extended miles and never had a problem. The new owner, on the other hand, pulled the rear and dropped in a V8 QC. So my answer is, Yes it will survive, but have spares ready.
I agree w/JRblack30, it should survive just fine! I have several friends w/the exact set ups & similar (1932-1934 rear end) as well as early Model A quick Change rear ends & they are ALL in fine working order. So use your A rearend & put the money you save into your machine! SOunds like it's gonna be cool, hope you post some pics once things get going. Cheatercarl
thanks for the info i think i will use it that will also simplify things a little. i guess its use what you got. im not a crazy driver and the modified should be light so hopefully it will survive considering it wont be much over stock as far as hp.
Not even a built 9" will survive if it isnt properly shimmed, that is where a lot of people have problems, a worn out, out of adjustment rear is significantly weaker than one that has proper setup Might be an idea to give it a good onceover
There is a lot to be said about just getting your rod to where you can drive it then updated it as required one piece at a time. You'll enjoy the beast more if you drive it and if it's fun you'll keep it longer. If your a working man, it's hard to come up with the time and money that it takes to build & finish a project all at once.
I've built several like this, and they were fine. Just try not to dump the clutch while it's in reverse. That's the weak point in the Model A banjo's. Also, go ahead and plan on making it an open drive. That itself helps the rear end more than you'll ever know.
In a light car like a modified it should work fine. I have one in a sedan and have had no problems but I have not abused it. Neal
