That's the trans I'm saving my pennies for! Close ratio FTW!

Please post lots of pics when the trans is in. Also something I'm looking at.

So here’s where some big hiccups came into play. When I went to set the motor and trans into place for the first time I fought the mounts for 3 weekends in a row before I figured out it was the polyurethane inserts I got from Holley. Not blaming them, must’ve just been a bad batch or something but they were preventing the motor from sitting flush all the way in the mounts. Got really frustrated at this point just because I wasted this much time fighting these mounts. I called Holley and they sent me new ones out no charge, but I had ordered ones from Summit which were energy suspension and they ended up working out perfect. The motor literally dropped right on and I was able to push the bolts through by hand.

The old poly mounts that I fought.. Literally tried everything. I left everything loose so I could shake the motor and pry it which ever way I needed too and nothing worked. Double checked the mounts on the frame pads even though I had drilled/mounted them exactly how Holley said too.

Here’s some pictures of it before I just recently pulled it out to fix a couple of things.

It was a huge relief to finally see it sitting between the frame rails.
Here’s my next problem that I have yet to figure out, The motor is hitting the firewall on the passenger side. The only thing I can think of or to put the blame on is the notorious “gbody tolerances”. Even then it seems excessive to be touching like that. I would understand and think it’s reasonable if it was tight but something seems off.

Any ideas??

It's not the body's fault. The motor mounts are wrong somewhere.


LS swaps are easy!

I hate to say it, but if you don’t want to change motor/trans mounts, you can loosen the body bolts and slide the tub back a little.

if you look those mounts are one hole to far back on the chassis.

Good eye, I think you may be correct.

the rule of thumb is one mounting eyelet should be handing off the front of the cross member at the bottom.
