I have a 377 SBC. My motor seems to suck a ton of fuel (Alky) into the oil pan. I'm figuring its getting past the rings. The machine shop didn't really get the bore as smooth as we wanted. Anyway, I believe its a 960 alky carb. When you romp on it hard and fast it will kill the motor. Don't know if its a lack of intake vacume, too big of a carb, or something else. Would a motor want a different ign. timing for alky or would the same for gas apply? I can't afford another anything so I have to try to make what I have work. Any ideas??

Also,, I believe we have a power valve plug in the back and we run a power valve in the front. We changed jets from way big to way small and everything in between. Didn't change that hesitation under hard and fast romp acceloration.

Probably a combination of things, but first, it's too much carb for that motor.

Hey butch i have a carb you could give a try, its a Bg gold claw with the 830 venturies in it. I have it with me at the track so if you run into probs come on over and grab it. The allky in the pan is normal for this time of year in are area, I try not to sit and idle to long befor i go on the track. Once you hot lap it should clean up unless that carb is dumping to much allky.

Thanks Craig. Hey,, I say your response to the legal quote. LOL You know I would NEVER think you were cheatin'!! LOL Thanks for the offer. I might take you up on it. I know the milky oil is normal. Just seems to me there was more than normal in my pan. I had some oil (Milk) blow out a valve cover vent a couple days ago. I dump the oil and put it on the stove to heat the methenol out of it. Seems extream to me. We hope to get some laps tonight and see what happends when we get it to temp. We have a 406 with a DANDY set of heads we are getting close to being ready and want to try it too. 406 is a flat top with milled heads to a 53.5 cc chamber. The 377 had domes to get 64cc heads to 12.5 to 1 comp. Thought about the 53cc heads on the 377 but I think that would be too much compression. Don't want to break the block.
Anyway,, hope to do some testing tonight.

I never heard that rumor about you and rules. But,, seems that will pretty much always be the talk when somebody is doing well. Personally,, I know how hard you work and how much research you do. It's very obvious that you arn't a casual racer and you do love the sport and do your work. Alot of times those speaking of the rules arn't following them like they should and STILL can't keep up. So,, they think if they are breaking rules and not winning, those faster REALLY must be. I know better than that. I have seen some really dominant racers before and it was because of experience, hard work, and talent. **** ,, they DIDN'T need to cheat. They never wanted to take away from their accomplishments by cheating. Especially in their own minds.
Anyway,, Craig,, Keep up the good work and I really hope to put some laps on tonight.
Thanks again.
