So where is the modification on your frame stands? They look almost identical to mine!

Looks good. :thup:

Those motor mounts look like the old style Chrysler mounts, with the studs on both sides (The rubber part, anyway).

Are those the bread-truck mounts that you used?

I want a video clip of this thing! :evil:

That's what I like to hear Mike! They're 2.5" shorter than they were originally and the at a slightly different angle.

The rubber bread van mounts are the same as the first gen dodge cummins mounts.

Yep, that turned out really nice. Kind of wierd how far back it sits. I saved the pics for motivation and I like how you did the stands. I was also wondering about that on my swap. I like the hydraboost too. The 6.9 has a vacuum pump, but it seems cluttered sompared to the 4bt.

What is the Hydraboost out of? I have been thinking of doing that to my 72.

That H-boost is from an '89 astro van. The adapter plate was a bit of work, but not bad overall. The master and the rest of the brake system is from a '77 F-250 4x4.

I still need to do some serious organizing in the engine bay. It looks cluttered to me just because hoses and wires aren't routed neatly. I'll get it all buttoned up in time.

The engine does sit back further than it would seam it should, but I think it would look worse if you tried to center it front to rear, not to mention make it impossible to run a manual. The plus side is there's a lot of room to get under the hood and move around.

I wonder if that is part of the reason it runs cool? All the air space around the motor to dissipate heat. I'm still fighting 21 years of dried grease...

:eek: a guy brought a 68 nova into my buddys shop. somone stuffed a big block and a 5 speed into it. also has a 9inch with disc brakes. rust out junk otherwise. well the 454 fit but the headers tight. so the guy just beat the tube in on one of the cylinders until it was 3/4 smash closed maybe more . well it burn a valve and he wreck a new set of super comp hookers headers. why not get the right ones that fit? because people are dumb. thats why they have that pic there. :wink:
