"NOT" Like a glove

That's a "NO" on the factory A/C system they are a waste of time. Very heavy (~100 lbs.) and originally designed to run on R-12 Freon so converting to R-134a just makes them less efficient. Since you already have a 440 up front it would be wise to find ways to keep the weight down.

As far as the stall converter that depends on how good the quality is and whether or not it's designed to run "tight" when cruising around with light throttle which makes all the difference in how nice it is on the street. What brand is it?

see you have raised port heads in the pic, look like victors or procomps. that`s going to make everything tighter -harder to do.I have an aftermarket front end under my 68 fastback, the throttle cable is a little problem by itself, the headers weren`t real bad w. no torsion bars, bought a set of used TTI`s off a member in wichitaw and straightened a couple of tubes out, they worked real well-just not a lot of room. hole in pass. fender for # 6 plug, # 5 is the worst, and it`s a ***** because of the steering column-right up against it all most. be careful, its easy to crossthread that one in the alum.head. the header install is bad enough for 1 guy (heavy when you 68 yrs.old w/ some physical hangovers from wrecks. the heater motor will have to 'go" w/ those heads,( put an aftermarket hotrod heater(small) in mine just for defrosters did u have dist. clearance issues? I had to do a lot of grinding on my procomp victors to get a f.a.st. 2.0 dist. in it, it`s a short one like a chevy. just drove it sat.for the first shakedown to see what needed attention. HANG IN THERE ,first time mine has seen daylight in 5 yrs. let me know if I can help w/ anything--------bob:coffee2:
