Potential FED Build
lake_harley:
Don I tried sending a PM to you and wonder if you received it. I can't find anything in my "sent" box, but maybe I forgot to save a copy there?
I had a number of questions specific to your car and thought contacting you directly might be better.

I'm still in the "potential build" stage on a FED, but just in case this actually moves forward I bought a 8 3/4" Mopar rearend housing with axles and brakes today. It came out of a A100 "Little Red Wagon" sort of truck and although I didn't measure the brakes it appears they are 10" X 2.5". I settled on a Mopar as opposed to a 9" Ford for the simple reason the axles can be cut/re-splined quite a bit cheaper than buying a set of aftermarket axles. To do the same with a 9" I'd have to find something with 31 spline axles and everybody seems to really be proud of them. Seems that someone also mentioned that the Mopar rearend is slightly less bulky in size to give a bit more room in the cockpit. I can handle narrowing the Mopar housing myself when that time comes.
A friend mentioned he had a 3rd member that I can get at a really reasonable price. I believe it's a 741 housing, but I'm not positive. I'll probably pick that up too thinking even if it's a 741 it would hold up to my projected 300-ish HP SBC.
Another thing I've been watching for on Facebook Marketplace and Craigslist is a used pair of slicks and wheels of appropriate sizes for mock-up purposes. There seem to be a lot of used and abused 10.5 X 15 slicks out there but wonderif I'd really need that wide of a tire to hook up only 300 HP in a FED? I'm thinking a relatively tall tire, perhaps about 29" tall? My un-educated gut feeling is that a 29 X 9 X 15 might get the job done with my projected HP and the car wouldn't be dragging the extra width and possibly weight down the track. I'm looking for input here, so fire away.
Anyway.... although a baby step it was the first step toward a FED build. Now if I could just sell my Willys to make room and free up capital.....

I know a guy with an inline-powered altered who uses 9 x 29 slicks.
It runs 8.30s in the quarter.
He is the reason I'm downsizing from 12 x 31.5 tires next season.

You want either a 742 or 489 case, the 741 pinion is the weakest of the three

I did receive your email and took a few days to reply, hope you did get the answers to your questions. That being said, you mentioned that the 8 3/4 that you have has 10 x 2 1/2 brakes and respline the axles. Do you plan to use the drum brakes, if so I have a few suggestions if your interested. I'm saying that as a budget builder who had to make a lot of parts rather than buy them.
