WAY better to go to a modern lighter rod, that's already set up for full floating pins. Just a lot better deal all the way around than using rods with zillions of cycles on them already and getting them rebuilt with new bolts, etc.
Also look closely at Larry's example of a relatively "low" compression 455 SD build and it's potential. They don't even grumble with those big HO Racing cams in them, yet we continue to see folks putting little tiny cams in them, then making no more power than a similar 455 build with 6X heads on it. The 455 SD is a factory "race horse", cam it up and let it run!.....IMHO.......Cliff

I agree 100%. In the past I ran a set of stock 71 HO heads on a 455 w/flattops. I had an Ultradyne 239/247 112 LSA. It only had 8:1 and ran great. Pushed a 3965 pound car to 12.70. On 87 octane.
