Subject: converting 1970 BB to diesel Author: John G [ Next Thread | Previous Thread | Next Message | Previous Message ] Date Posted: 03/ 3/ 02, 2:17pm Just got a 1970 FC (seen on this billboard), got within 7 miles of home before the engine gave up the ghost; The original generator didn't work, so we will either put in some (probably) major work or replace it. As we are essentially putting in a new engine and generator, this seems like a golden opportunity to put in the powerplant of the (my) future. wanted to see what experiences/advice could be had before going diesel or gas. I wonder about the weight of a diesel vs the 390 CID ford engine I am replacing - how will this affect the suspension? Do I need another transmission to handle a diesel?(I am looking for a mechanic to help me decide if I need to replace the current one either way). What other questions should I be asking? I am planning on towing a minivan - sometimes Any advice or other questions (am I nuts?) appreciated Thanks in advance John G [ Next Thread | Previous Thread | Next Message | Previous Message ]

His name is Joel Trusty, 317-823-6821 and he is in Indianapolis. Tell him that I sent you, and if you decide to buy, email me as I'd like some parts too if you want to sell some of them.

[> Subject: Re: converting 1970 BB to diesel Author: Dale [ Edit | View ] Date Posted: 03/ 6/ 02, 5:01pm I'm in the process of changing an engine in a '72 BB. It originally had a 391 Ford and someone had it changed to a 534 Ford before I purchased it. After pulling the engine and doing work to the exhaust manifolds in '96 and then taking a trip across the country I realized that the power was low and the milage was even worse. Down to 3.7 mpg in the mountains of Oregen. I decided to change the engine. I bought a truck with a 3208N and a 643 allison. I've found that the engine fits in the engine compartmant quite well. There had been some trimming on the frame when the 534 was put in, but it is nothing extreme. I'll need to trim the top flange of the frame alittle more and then should be just fine. Side mounts for the engine will be the biggest challenge. I've looked through a few junkyards but couldn't find mounts that would work. I'll just build my own. Also, will need to shorten the drive shaft a few inches and chage the yolk. There are alot of little things that need to be taken care of. Of course I'll need to change the ratio and am condidering switching to air brakes. It is hard to know where to stop making changes. I can't quite imagine paying a shop to do the switch. I think the labor bill would be crazy. I'll update more later on or you can e-mail me directly. I do have the 534 and MT42 allison for sale if your intrested. Dale [ Post a Reply to This Message ]

You could simply install both of his axles to update to air brakes. - Jeff [ Post a Reply to This Message ]
