Help!
I want to thank everyone for their help so far but I still can't get my 68S to run right.
It still won't rev over 3500-4000 rpm. I've put on a new fuel pump,coil, did a valve adj. and just rebuilt the carbs. The car starts good, idles great. No funny engine noises. It runs good up to the point it starts backfiring(through the exhaust)and looses power. The only thing I've done to make any difference at all is to bump up the timing to about 35 BTDC. Then it will pull up to about 5000 rpm but the engine pings when I take off. It seems like the faster the timing is, the higher the engine will rev. The strange part is it only does it going down the road, in the driveway with the correct timing the car will rev to 6000 rpm and sound good.
I haven't been through the distributor yet. Could the cam timing be off? I'm running out of ideas.
