73 Chevy 350 firing order: 18436572 countercockwise
the 70 engine came in a couple of different horsepower ratings and had higher compression ratios than the 73 model 350 and the 350 of 73 only came in one horsepower rating and was smogged down with emission controls.
the 250 cu in 6 cyl. and then the 307 V8 and the biggy option was a 350 V8.
Yes. The only difference besides the inside door panel is the 73-74 doesn't have the wing vent window like the 68 -72.
If that 55 originally came with a small block 265, the 73 350 would drop in. If that 55 had a straight six, nothing would bolt up to the 73 350.
73-74 Chevy van.
set the point gap to achieve 30 degrees dwell.
Install a 350. I hav4e had friends pay me a fortune to try to get a 307 to run, and never could. The bore and stroke configuration, just does not work for high performance.
No, the brackets & everything are different since the body changed that year. The 73 has that wide strip between bumper & body so the curved sides longer to take up the gap. I think wheelbase also changed slightly. The 73/4 are the same.
