I'll go ahead and tell you what I got. I have a 57 210 2 dr. post. I weighed it without me and it is 3370lbs. So with me, lets just round it up to 3600lbs. I have a 350 bored .040, flat tops, 291 double hump heads with 1.94 valves, comp cams XE268 cam, edelbrock performer intake, holley 600, headers, stock HEI, saginaw 4 speed, and a open rear with 3.55 gears. When I raced, I didn't pop the clutch because I didn't want to spin. I eased out on it and then nailed it after I was moving. That seemed to work ok. However, it just seems my engine doesn't pull real hard. I was hoping for a 14 second time slip, but could only get mid 15's. I've checked the compression and its good. My cam didn't wipe out during break in. My fuel pressure is good. I've checked all of the basics. The car does seem to run rich all of the time. I've had to change my sparkplugs twice within a few months. I've tried 3 different carbs and that didn't help. I know my car could benefit from a super tune. I'm wondering if my heads could be the culprit. they haven't been professionally rebuilted. I just lapped them myself and put in new valve seals and springs. I do get a puff of smoke sometimes when I start it. I think thats the valve guides. I would like to race it again this spring, but I know it needs some attention somewhere. I had a 79 camaro with a similar built 350, auto tranny, and 2.73 gears that was almost a full second faster in the 1/4. It ran a [email protected] People have told me its the aerodynamics coming into play. I could see that if I was trying to hit 200 mphs. I don't know, anybody have any suggestions or any timeslips to compare mine to?
