Super Six install on 1974 Dart

I used Slip Plate spray on the exhaust manifold, something like $13 online. I also used it on a lot of the brackets, bolts, and things that the factory painted black: steering pump, fan pulley, kickdown linkage, etc. It contains graphite but it's different from the graphite lube spray sold by WD or PB. It's more like a paint. After you spray it on, you can wipe off the excess and it leaves a pretty clean surface. I would definitely use it again. [EDIT: I forgot to say that it's been over a year and a few thousand miles, and the Slip Plate still looks brand new.]

The 2bbl definitely gives the car more pep. That said, I'm not convinced my 1bbl Holley 1945 was working as well as it should have; for all I know a good 1bbl would have been about the same as the 2bbl. Also, I think I need to open up my exhaust a bit if I really want to get the max benefit from the 2bbl. Super Six cars came with 2 1/4" exhaust and I still have my stock 2" pipe.
