Justin, I know of a few FED for sale , one is a roller JF car with out engine or powerglide, in Phoenix it has won NHRA Comp and Heritage races.
I think his engine is out 44" with 225" WB, he also has a trailer that will take a 225 WB car. Also there is a JF roller for sale that will require some work, last time out the air bag under the car broke and some tubing will have to be replaced. I think its 185" WB with the engine location at 44" it was running a Ford so as with any car you get , you'll need motor plate and front mounts. This chassis is in the LA area, last I heard he wants under $5k. In Walnut Creek there is a JF 185"wb roller for sale racing the last two years the engine is 42" out I think.
So call me if any of that is interesting
