yep, right at 150, well 148-152 or so. Close enough for me. I got a good snap on compression tester and I trust it. If it were an autozone special I would have checked to see if the needle were sticking. I had to do it quick on my lunch break and didn't do it wet. I didn't really see any reason to.
I just put in the curve kit with the stiffest springs. Minor difference in taking off. Big difference in idle and the transition to power mode. Now if I can just keep the vaccume advance out of it while it is floored I think I will have it made. I think I need to get one of them gm things to kill the vaccume to it while floored. I think they close below ten inches if I remember right. It is still getting 38-40 at 1800 or so.
The test strip I am using is quite unscientific, Just 5 telephone poles on a back road and I take off from a stop and when I get to the 5th I look at the speedometer. It was at 45 yesterday and I am up to 55 today with the hotter plugs and advance curve in it. I am just leaving it in drive for testing. If I shift it and let the rpm go up I can hit 70. Not too bad for a 6500 pound truck.
I am gonna try to do the rejetting on the carb and get that vaccume break or what ever they call it before I mess with anything else. Has anyone had any experience with a edelbrock 1406 at 3500 ft altitude? I was gonna get the kit edelbrock recommends in their owners manual but if there is anything else I should know please let me know. The plugs are still black so It needs jetted but I was wondering about reducing the shooter size or anything like that. Or am I thinking about holleys too much. That is all I really have any experience with.
My wife is going in for surgery tomorrow morning so it may be a couple days before I can get back here but I really appreciate all the suggestions so far. Thanks a lot guys.
