Hey all, last fall I was smoking my tires trying to impress my girlfriend, wound the car up a bit too much and broke and bent a couple pushrods, and rocker arm studs. Anyways, since then I've thrown new pushrods, rocker arm studs, nuts, threw the engine back together. I didn't inspect the cam with a fine tooth comb but it didn't seem that any of the lobes were wiped out. And to verify I took off the valve covers and cranked the engine after adjusting the valves and all the arms were popping up and down just fine. I did a compression test to make sure I didn't screw up a valve and she was showing 150-160 psi all the way around the car. I don't have a timing light but I've been messing around with positons of the distributor playing it by ear and no significant affect. The cam isn't really known for low end performance unless it's in a bigger engine or with a higher stall convertor, but I used to be able to smoke em' halfway thru second from a roll. Now all I can do is brake torque to get anything.
I guess I just don't understand why it don't have the get up it used to. It's still decent but nothing like it was. Any ideas would be greatly appreciated. I will say that I'm not a carburetor person and it has a Holley 750 that I really don't want to mess with but I feel that may be the problem. I know these aren't great on gas but 20 bucks worth is just enough to last a days drive. I'd appreciate any help.
Thanks
Brandon
