55 in NH build

[Kevin_C]

Hey guys, I'm looking for some guidance. I bought this truck sight unseen and I'm really impressed with the amount of work the PO put into it so far. It currently has a built 305 with a 4 speed. My original plan for a truck was IFS,LS3 but as I start to build a budget I realize there has to be some compromises. I'm currently looking at a 406sbc as it will drop right in.

Some area's I'm looking for options on are the following:

Front suspension: The PO spent a lot of time and effort fabbing a lowered Ibeam with a power rack and disc brakes. steering seems good but the truck has settled and the tires rub. is there a way to raise the truck up slightly, stiffer spings etc.. anyone have any experience with a lowered ibeam. Do they ride like a rock? If I can make this suspension work it would save me a lot of time and money if I don't need to go IFS

Rear suspension: truck has original rear end with 390's and 5 lug adapters. Between the gear ratio,non posi and the 6 lug I was thinking of swapping it for either a 9" or 8.5" with a 4bar setup. Not sure what width rear end I should be looking for.

Doors: so I kinda have doors but I don't think they can be used. PO was going ultra light weight and although he repaired the exterior the inside has been gutted. basically just a 2-3" lip around the perimeter. Been looking for used but also wanted to know if one place is better than the other for new doors or are they all made in the same place.

Fenders: swapping the fiberglass out for steel

Bed: plan on cutting the frame and turning into a SB.
