major mods.........The front frame tie will be it the way if you ever need to take off the pullys. Needs to move forward 2" and be much stronger than stock. Motor mounts need to be fabbed up. Radiator needs to be custom and all the way forward. I moved mine as far as I could and found a thin pusher fan from a benz.

Exhaust needs to be custom made. Header wouldn't fit, but stock 430 manifolds fit well. Frame needs to be patched everywhere and reinforced. Steering needs to be reworked. Brackets for the PS need to be fabbed. starter will need some cutting to the adapter Jeep used.

On the good side. Motor fits between the inner fenders and bolts up to the th400. and theres plenty of room up top. Everything is accessable easy.

Hope that helps. FYI It took me 2 months to get it all together.
