I've heard it done, but I thought it was only done on the older small blocks......could be wrong though.
its supposed to give more torque and run smoother

eh I wrote a thingy about it back in auto school. It was on HP tv a long damn time ago so I did some research online..

The 4 7 swap isnt possible in a gen III engine so... yeah. The firing order is different as well.

Worked 11 hours.. and now this

That's because GM already did it for us.

At the machine shop I worked at part time we did an experiment on a roundy round motor with the 4-7 swap. A little 406. Didn't find anything on the dyno at all except that it seemed to switch the exhaust temps around on 2 cylinders from what they usually are.
