I might change the whole build from drag truck to mold prerunner.
But I can't seem to find any way to lift the front end, other that bigger
springs, which won't really help the overall suspension travel.

Any ideas?
Our should I just keep the supra-truck as a drag truck?

 

You're not going to find much help with lifting one of these. You could make custom ball joint extenders and lower the front lca to not destroy the suspension geometry. Look up lift kits for any IFS toyota to get a better idea of what I mean. Other than that you could do a body lift all around. You can get away with a 1" body lift without having to modify anything... if you go any higher you'll have to add a steering extender and extend the fuel filler coupling. Neither of these options give you more travel... but your truck will still be higher

 

Chassis swap.

 

I started to round up parts for my 77 chinook.

The rear so far is going to be simple. Chevy 63in springs (looking for 3/4 tons), and a 14 bolt semi floater.

The front I have no clue how to lift it using the factory stuff. I'm looking for a wagoneer dana 44 for mine. Custom suspension no matter what.
