I starting a new thread on my 37 Plymouth pickup and its transformation from marginally driveable with a 289/C4 to a 6.4 Hemi/545RFE/4.10 Dana 60 monster.

Today I dropped it off for getting a 4 inch mini-tubs in the bed so the bed is even with the frame rails so I can fit these 295/50/15s on 10 inch wheels under the truck. The next step will be to order a narrowed Dana 60 with 4.10 gears so we can do the 4 link rear.

This should be good.

We are going to do it in stages, get the rear 1/2 of the truck done first then tackle the front including doing the motor and trans along with a Mustang II front suspension, 4 wheels discs as well

What do you guys think of these brakes for the rear?

Those tires are going to look great under there.

"........4 inch mini-tubs in the bed so the bed is even with the frame rails so I can fit these 295/50/15s on 10 inch wheels under the truck....."

Yeah , I had to go look under the back end of mine. That would be a fairly easy job to pick up a bunch of tire clearance.

Those brakes should be plenty for the truck.

Looks like it will be awesome. Tires & brakes look perfect and swapping out the old Ford 289 for a 6.4 Hemi is a big plus! Good luck with the build.

Milke, I don't think you can find a much easier vehicle to mini tub

I got the crate Hemi about 6 months ago, hope it's sitting in the truck by August

Regarding the rear brakes, let whom ever is building your Dana know what brakes you wan to run so they can use the correct housing ends and axle offsets.

As for how they work, well got a 98 Exploder with those brakes and they seem to work fine.

Definately will let the rear end builder know, I need just a bare housing with axles to do the 4 link, then I will have it all powdercoated before it gets gears

I suppose you already saw these?

John, I already own the crate 6.4 and 545RFE

Yes, you have the fresh new good stuff.

I just mentioned it due to:
1. Additional parts you might want (driveshaft core, accessories, harness connectors, TPPS, etc.)
2. Having an engine/trans to fit without worrying about damaging the fresh stuff.

I assembled a 340 once starting with just a block, crank and rods. It ended up costing more in time and money than if I had just started with a complete motor. That's why I tend to look for stuff like I posted, even if I end up with more stuff laying around. And my yard proves it!
The project sounds great and should be quite a handful when complete.

Angled 4 link or straight with a pan hard bar?

I haven't decided yet

Mini tub progress

Picked up this Dana 60 today for $100 to be narrowed, it's pretty clean, came out of a 73 Ford F-250

Mini-tub progress, it's looking great

Underside

those tubs will stand up to anything dumped into the bed ! looks good !

Thanks

Got the 37 back to the shop, the 15x10 wheels with the 295/15/50s are on it. They stick out past the fender about 2 inches, so I'm thnikng of going about 2.5 inches per side so need a rear end that's 5 inches narrower.

Those tires look good on the truck. Thanks for posting the last picture, I had wondered what you did for a gas tank. The picture also reminds me that I need to get around and start on my rear roll pan.

when you narrow the rear, are you planning to move the springs inboard or under the chassis ?

Generally a 4 link has the springs inboard of the rails.

He did say he was going to a 4 link in the initial post I believe

i missed that, or in reality, just kinda forgot ! thanks for stirring up my memory bank ! [dadgum oldtimers anyway !] lots of room gained by using a four link.

I was thinking the same thing. (maybe)

It's an Isuzu Sidekick tank, only bad thing is it's only 11 gallons, I bought it brand new off eBay for around $100, you can have it when I yank it out if you want it. I got a 17 gallon fuel cell coming that fits in the same spot

Springs go away with 4 link so I can stuff the tires inboard more

What is the first gear ratio for the transmission? Most 6.4 cars have a 3:09 rear gear.

".....you can have it when I yank it out if you want it. I got a 17 gallon fuel cell coming that fits in the same spot......"


Thanks for the offer but I'm happy with my 15 gallon beer keg

i missed that [really, just forgot !], and should have known better !
