Well guys went and checked it out today and I guess he got the carb all jetted out the way it was supposed to be and everything seems to be fine car runs good has a lot of power and no more glowing headers. I still just wonder how much better will it run if he were to set the timing chain on zero so he would be able to advance it. what do you guys think?? Also what do u think about getting a 650 carb or if this one is jetted out already is it alright like it is? and what about a carb spacer I here that they can act as if u had a bigger carb but u just have to try and see if they work out with your combo so i figure with the calibration kit and jets i added to the 600 carb and a spacer i might be at 650 cfms. Tell me what u think.

Actually the 600 carb is overkill for a 350 anyway, so if you want a 650 or a 750 go for it. Don't think either will hurt anything other than your gas budget.

Okay now I've been driving the car and at idle the temp get at around 190 deg. after driving for about 20 min. while driving it stays around 160 deg. But this is without a shroud but I have an electric fan. Will the shround Kill this problem? Also In the car the temperature light is flashing on even at aroung 160 degrees?
