Installing Headers...
I am putting some hooker headers and sidepipes on my (as of today) stock '80 L48. Cam, heads, etc are in the plans but will be a few weeks down the road. When I install the headers and remove the stock exhaust will the car run normally? Will the timing or anything else have to be changed immediately when I take the stock exhaust off? I am just trying to know what to expect. It is in good (slow) running condition right now. Thanks.

the tune "may' need to be changed but you should be fine to cruz and see :cheers:

You shouldn't have to make any changes... :)

A richer fuel mixture would yield a few more HP with the free flowing exhaust. If the new headers get to glowing cherry red hot, it might be an indication of too lean a mixture. Advance the timing a couple of degrees too. As long as you dont get spark knock yur ok.

I just pulled the stock exhaust off. I think it weighed about a ton or so!!! Haven'st gotten a chance to put the headers and pipes on yet though.

I've put headers and a true dual system on my '80 L48 and didn't have to make any adjustments. Sidepipes should be very nice though. Of course we'll need to see photos. :yesnod: :thumbs:
