Exclamation 455 olds performance upgrades

I have a 455 olds. I just opened the motor to find it needs an overhaul. What is the max I should bore and what are the best performance upgrades for this. What, with good rod bolts, is the most I should spin this motor. I need the most rpm I can get.

Edelbrock has a nice performer rpm package for the olds 455, with an option for aluminum heads.
I would go .60 overbore.

my father rigged up a 455 for his 68 Cuttlass with all edelbroch parts. If I remember correctly he has done all but the heads, which are still factory.

Intake manifold was a torker 2 and he got the Performer RPM kit with carb (750 cfm?) cam and lifters an a few other things like high flow pumps, etc. and a good exhaust. It runs real well (or rather, ran.. before he hooked up the juice and warped some of the parts :p ) and he was running high 12s at the track when he took it. Add some aluminum heads and that should kick it up nicely.

It was just a street car, but he decided he wanted to give it some juice without upgrading the pistons, etc and melted it OOPS! back to the shop it went, and there it sits until his new house is finished being built.

I am considering buying his "spare" and building it up for my Omega, but it seems like the parts quite expensive compared to a 350 Rocket so I may just try to find one of them to fix up.

Please let me know how it turns out.


EDIT -- LOL. Just looked at the date of the original post.. something tells me the guy isn't checking this thread much anymore
