Cliff,
I don't think you came off rough or condescending. You stated why you use what you use and did not trample on any toes. I have learned a lot from this thread. May even start some arguments at work next week.  Dan Remember when sex was safe and Hot Rods were dangerous? The DotRod rides again.

Great discussion all around on piston designs and choices.
Like Cliff said, NO WAY I'm skimping on pistons when spending the kind of time and $$$$$ on any performance engine! Greg, according to my machinist, the 4.200 bore size choice (.049" over) allows one much more choice for street (1/16, 1/16, 3/16) rings. That's why we chose that bore for my '72 455HO Formula engine. No doubt on losing those cast rods either. We chose Eagle H-beams for mine. Check EVERYTHING on that engine. I wouldn't put a Thunderbolt engine in my "lawnmower". Might ought to spend a couple of bucks on your heads, too. Bowl job, SS valves, bronze guides, good springs and valve seals are all $$$ well spent. If you're in the Houston area, myself or several others here can give you good referrals to local machine shops. Hope this helps.

Thanks for the input guys. My car has been parked since 1985 and when I finish putting it back together I would like to drive it and race it for a while without destroying anything. I had a 400 in it before and I am looking forward to feeling that 455 torque. I am hopeing it will run mid 7's in the 1/8 mile. My buddies Camaro runs 7.50's and rides the trailer to the track. I would like to drive down with the A/C on and run with him. He has been giving me a hard time about getting it running for 10 years!!

I purchased the engine complete from tbolt engine rebuilders in Houston TX. It is a stock rebuild and has 6-X heads on it, standard crank and .030 overbore. Could I upgrade to .030 Forged Pistons and beter rods without having to mess with the finish or size on the bore?

I just purchased a rebuilt 455 with Hypereutectic Sealed Power pistons and stock rods. I want to duplicate the 455 Car Craft Built with E-Heads and Comp XE-274 cam. This engine had 500hp and around 580ft lbs of torque. This engine peeks at 5200rpm. Will these pistons live at this level of performance with street and seldom strip use?

Rob
My post was just an opinnion on the subject. It was not directed towards anyone. You did bring up a valid point to consider. I agree that hyperutectic pistons are more brittle than standard cast or forged pistons, and in the event of failure could cause more damage to other parts. Tim C 65 LeMans, 3550lb.
