302 V8 engine/trans swap

[knucklehead]

Hey guys , I'm having a problem with a V8 conversation. The engine towers are welded in and the engine,trans and transfer case are all connected together. I dropped the entire unit in and it looks like i welded the engine towers 1/2" to far back because the drivers side valve cover is hitting the firewall. I do have the trans and transfer case raised with a floor jack.
Now the other problem is the transmission crossmember is way to far forward for it to line up with the holes in the frame. It seems like the entire unit should slide back but that would put the engine an inch or two into the firewall.
I'm really scratching my head . Did I install a 6 cylinder trans ? Need help bad
I'd like to talk to someone on the phone. Thank you

If memory servers me, there's a I-6 bellhousing & trannie., V8 bellhousing & trannie., and a V8 C4 auto-trans. bellhousing.

Post up some pics......

Hi, the V8 transfer case adapter is longer then the 6. I think the tranny cross member bolts to the chassis in the same place or you would need different driveshafts. Good luck

And your engine could be in just the right spot with your trans a little too low on the jack.
Even when it's set up just like the factory, there is hardly enough room to put your fingers between the back of the head and the firewall!
So the fact that it even clears means that it's close.

Is there any more room to move the trans upward into the tunnel? Or is it touching now?
You stopped because you reached the proper angle on the engine? Or something else is limiting you from tilting it forward just a bit?

And yes, if you're using your original six-cylinder trans and adapter that could be the problem right there.
How much is the misalignment from the frame holes to where the crossmember wants to land? I think we should be talking just about an inch or so, but I really don't know that for a hard fact. Others should know the expected differences.

Oh, and last but not least... What is the condition of the body mounts and insulators? Are any damaged, and are any of the insulators original rubber ones that might have crushed down over time?
Body lift?

Good luck.

Thank you to all that replied. I realized the body mounts were not installed. Lifted the body up 1" and the engine bolted right up . Thanks again

Well that'll do it!;D
At least part of it anyway. Did the trans crossmember holes line back up too?

Thanks for letting us know.
