i would also try to cut as much weight off the front end as possible. like: fiberglass hood, delete fog light brackets, aluminum pulleys,battery relocate, aluminum carb heads etc etc. otherwise you will have a hell of a time transferring the weight to the rear.

Get a Maximum Motorsports K-member.They are the best HD K-member made and to support the weight from the Fat Boy you will need that strength to be safe.
You will also want to add a strut tower support and maybe an X brace for the K-member.
I would also go with some coil over struts so you can select some springs to support it and easily adjust your ride height.


I have thought about doing something along those lines myself as I have several 429/460 engines and a C6 or two sitting in my garage, but my injuries have kept me from doing much of anything for the last few years, so it may be an un-achievable goal for me at this point in my life.


A 460 would be cheaper no doubt, but an aftermarket 351W block can be bored and stroked to at least almost as many cubes nowadays, then add a turbo or two and you can easily reach over 1000 HP. I intend to see just how far I can push the stock block 5.0 I have, then go with a Boss 351W block, bored and stroked to 427/428 cubes eventually and turn up the boost on it and see if I can reach the 1000 HP goal in a street driven Fox.

That's a **** ton of HP on a street driven car. It'd be a blast no doubt, just can't imagine not spinning the tires 1st-3rd at every stop you come to. Can't wait to see that build though.

Yes, it will be a lot to successfully put down to the pavement.
Figuring out how will be part of the build process.
I'm thinking that a rear suspension change to the Maximum Motorsports drag suspension may be mandatory, but I will see what my Lift Bars and adjustable uppers can do first along with some big ole' sticky drag radials.
First stop will be trying to successfully contain 600-650 HP in my stock 5.0 block.
P.S. Look up Nelson Racing and watch some vids of the insane HP in street cars he manages to put to the pavement.

That's my goal with this 351 dart build I'm putting together. 600hp to the pavement. I could obviously squeeze a lot more with my set up, but I think 600 will be plenty... until I get bored with it lol.
