    Ive got the same set up. only i've got msd 6al. my carb is 830 race holly. check and make sure the carb is getting enough fuel. I had to bend the lever over on the rear of the bowl to ride on the cam that ingages the back pump. put a "load" on your motor, leave your boat on the trailer at the lake and try to dial it in.

    I know this is off the subject, but I thought I'd get most 455 Olds owners in this thread. I have my front/rear motor mounts/flywheel out of my 455 that are just sitting around. I'm willing to get rid of them super cheap. Anyone need them? Offers?

    W&W,Need a better description than "bog" down. Does it die at 2000rpms? If you have a bad vibration at 2000 and can't go any higher,check to see if there is anything in your pump. Just curious... How did you achieve 200psi compression. Jethro

    Do you have a oil pan for a 455 Olds?

    I don't think he could do 2000 rpm without an oil pan! http://www.plauder-smilies.de/person/cheering.gif
