1978 full size Bronco with a 1st gen 12v - Page 3

American Thunder · 09-29-2009, 11:46 PM

My CNC machined adapter plate and flexplate arrived from Destroked today. I'm impressed with the quality, it's insane. I'm going to have to clear coat this adapter so it stays looking like this..

I'm not sure how much torque this SFI Cert. billet flexplate will handle, but it's probably a bit more than I'll ever need. It's really thick.

Wow that adapter plate is amazing, looks like gold!

Are those adjustable motor mounts you're using also from Destroked? They seem to be a perfect fit to the Bronco, along with the custom plates you fabed up, and the 3" body lift?

What torque converter are you using to match up the C6 to the Cummins? Is it a stock Dodge converter?

And just a note on that 9" rear-end, if you do ever brake it, I would look into a Dana 60 from a 78/9 F250, it should bolt in and very cheap. Just an idea. . .

Good job on the build, hurry up and get it done so you can tell us how it runs. . .

For the time being, I'm using a low mileage 460 C6 torque converter, to try to rein in costs. Next year, I'm having the C6 built to the hilt and buying a diesel low-stall converter for it. (I think it'll be stall rated at 1300 rpm)
The motor mounts are from Fordcummins, I liked the design. I wouldn't use any of their adapters, but their mounts looked decent.

As for the rears, I considered it, but I don't really want to use D60s, for a few reasons. Mostly I don't want the added weight and I don't want to get rid of the original 5-lug slot mags. To maximize acceleration and fuel mileage, you gotta get rid of weight that doesn't make the vehicle go faster.

It's not a heavy work vehicle or anything, it'll be a daily driven toy, basically. I think the 9" will hold up ok.

Looks pretty sweet.

I have a long way to go on my build but I am learning more and more as I read others builds.

That looking good. I wish I had that much firewall clearance in my 79 but I didn't want a bodylift.

I love it, You and I are brothers from different mothers lol. I used a forklift to set my engine cant stand engine hoists. Your gearing with 35's on 3.5 ratio is almost dead on to my 28's on 2.73 gears. Although I would travel farther for the same revolution you have the overdrive advantage. Its going to be very interesting how your mileage is going to look like, and We can compare it to my caddy. It seems these white sleds both weight the same too, I have 4300lbs on mine with me in it, Im not sure if yours was that heavy with you in the bronco or not.

I got the two group 31 batteries in it and I cut the flap out of the gan tank filler neck, cleaned it up and Im really close to getting done. Hopefully by the end of this weekend I should be cruising, good luck Bro and god bless hotrodders who put engines in vehicles for the sole purpose of enjoyment.

Thanks, you too!

The '78 Bronc should weigh about 4500 lbs stock, so I'm shooting for 5000 lbs when this one is done. I have a truck scale, so I'll know exactly how much it weighs. (once I get around to moving my brother's massive generator off the damn thing)

Sorry if this seems a strange question but I figured I would ask anyway.

In your 79, if you could imagine the steering column and all on the Right side instead of left do you think there would be enough room for twin turbos?

I am worried about were the steering column and linkages will go so I figured someone might know. I will be using a 97 Dodge 2500 chassis and putting the 75 f250 body on it. The ford is RHD. The dodge is LHD so I will have to convert it. Thanks for any help.

And I look forward to your build pics when you get a chance.

Oh an Aussie truck huh, cool.
Is the steering box and mounting position and all identical to the US trucks, just mirrored?

Worst case scenario, you could order up an aftermarket setup with carrier bearing so the steering shaft could zig zag around any interference areas.

I was just looking at an old big block Baracuda yesterday, and the guy had plumbed in twin turbos, but they were mounted behind the headlight locations on each side. It looked insane and awesome. (and it didn't touch the steering at all. heh)

Yes pretty much. Some setups they just run a gear or bar to go over to the normal(USA) side instead of a FULL conversion.

I just know that I will have to convert the Dodge to RHD and would like to still be able to buy a TT kit from guys in the states that bolts right in. Instead of having to make my own TT kit from scratch.

Looking at GMC/chevy steering it seems to be all out to the side of the frame rail so it would not interfere with the turbos.

I figure with all the possibilities out there I could just put a Ford setup or chevy on there and stick to the frame rails and be fine.
