| | 455 timing ?
Just purchased a 72 buick gs 455, build sheet says that engine has 10.1 pistons balanced, 280 comp cam, heads ported and rebuilt w/ stage 1 valve train. it also says that distributor rebuilt at 7* cent. and 16* int.
I am not sure were to set the timing with a timing light. it was set at O*btdc when I got the car but it looked like everything else was off trying to adjust for a big vacume leak. I have fixed vacume leak, car runs alot better but on initial start up it will hickup through carb. I have the timing set to 4* and trying to get the car dialed in.
thanks for your help.
