Awesome work!!! :thumbsup:
Don't worry about the haters with no imagination. It's amazing that there are still people out there that don't understand that you can get a running take out like you've got for a small fraction of the cost of a crate hemi or even a full rebuild on a 360 to bring it up to that hp level. Or that if you're capable of fabricating your own engine/transmission mounts that a swap like that isn't all that difficult to accomplish, you just have to be willing to do a little fabrication.
Just the work you've done yourself so far puts you ahead of probably 90% of the folks on this board. Lots of talkers, not nearly as many people that fabricate or even turn wrenches on their own stuff anymore. If you do your own work and put that old girl back on the road and drive it, well, that's more than good enough for me. Way too many checkbook cars and garage queens here already.
It was already mentioned, but if you're keeping the torsion bars you need to keep an upper half of your crossmember as well. It doesn't have to be complicated, but there does need to be something there to help carry the suspension loads that are carried in the transmission crossmember.
Keep up the good work!
