Notice the hydralic clutch and the column is cut down to the firewall. I can't tell if that's just an addapter plate or also a relocator for the MC. Thats the only way you'll get the exhaust to work on a 4-speed. Especialy with a 10 inch bell. It is tight on my 360. I have to use 1 1/4 off the 273 manifolds till I clear the linkage, bell and column. But anything is possible with enough money.
I've mentioned this before on another thread but there is a guy here in town that has a 64 barracuda w/ a 383. His solution to exhaust clearing was flipping the manifolds and running the exhaust through the K. A bit ghetto but thats hot roddin.
