Tom,

too soon to know. I have to break in the motor all over again. Some dude in a vette wanted to play on my way home with the car. I'm going to baby it for 500 miles, and then be gentle for the next 500, and then stand on it.

I did receive one of the first reworked carbs back from Roush, and I can already see improvement. My old carb (870 elec choke) NEVER ran worth a damn when the car was cold. I'd have to keep it running with the throttle until it warmed up, and if you tried to drive it would stumble. Tried adjusting the choke all over the range and no change.

New carb, fired right up, no loading up, ran great cold. They seem to have done a lot of work to make these run better. Interesting with my old carb I put the car on a chassis dyno and it was lean so we jetted up a few sizes to fix it. From what RED told me the new carbs actually have smaller jets that the old ones. Once I finish break in I'll get the air fuel. I also have new mufflers that I want to weld in, so I'll add some O2 sensor bungs at the same time to be able to check air/fuel without going to the dyno.

Did you pull the trigger on a new motor?


Daryl
