Projects 31 AA as a real truck?

How mean is your SBC build going to get? If you already have the 200, I'd use it. If you blow it up, you can always get a 700R4 later.

Thanks
May still find a 700 and keep the ZZ4 and 200 for the MG TD

 

Might be a good idea to crawl under there and get some measurements. IIRC the 700 is a bit bigger than a 200 or TH350. I know there is a heavy crossmember there somewhere but I forget where it is.

 

Plenty of room for 700r4. Went to Pamona lots of insperation. I sure hope stock front axle and frame work well with the one ton wheels and 70 mph.

 

Great.

Well, make sure your wheels and tires are up to the task and balanced.

 

1979 or so Ford f350 wheels not the stockers. I here they are widow makers

 

I believe "Widow Makers" were earlier and the Firestone "RH-5°" two piece design. Outer rim where the side ring and rim connect along the center line of the assembly. Not to be confused with the 5° three piece design. I'm not an expert but some good info here: http://forums.aths.org/PrintTopic172090.aspx
and here: http://www.fatfenderedtrucks.com/widowmaker.html

 

Thanks for that info. Makes me want to find out if anyone makes a modern wheel i could add stock centers to?

 

Hey neighbor, I had these guys swap my split rim centers into new tubeless hoops many years ago. It was pricey but the project warranted the cost. I hear they are contracted to Les Schwab now so you might be able get the local store to handle all the logistics, for a fee. They are over in Pasco.
