Tach for 82 T/A
So I finally got my 82 back on the road with a new 388. The problem is my tach only goes up to 6k rpms, the 388 can do 8 or 9 before red lining. Where can I find a drop in tach replacement? preferably on a budget.

Re: Tach for 82 T/A
Basic Operating RPM Range:3,000-6,500 ?
Am I missing something? or do you mean 6,800 -6,900 or 8-9,000 rpm?

Re: Tach for 82 T/A
It's been a 3 year project, so I missed that stat. Now I'm really confused...when I tuned my carb I opened all 4 barrles and it took my tach all the way back to 1000 rpms, like past 6000. So I asked the guy who is helping me tune the carb and he said 9000 rpms for the engine.... should this be posted in the engine foru?

Re: Tach for 82 T/A
yrs ago,i bought an '84 firebird cluster that had an 8000 rpm tach with redline at 6000-it may have came from an L69 H.O,AFAIK,84 cluster is pretty much the same as '82 except orange lighting .
