Do you know anyone running the road paver grind?
We use the RP in a 455 with ported #62's. It idles about as good as the 455 in my car, which to this day amazes me. Good street manners as well.
I quit doing these engines couple of years ago, but at that time the 3" main forged cranks were plentiful. Pretty much a waste of time/funds to overpay for a 428 or 455 block and use a factory crank, IMHO. This assumes the good forged cranks are still out there. I've had perfect success with them, most were from Star Galaxy. I do send all my rotating assemblies out to be balanced and cranks/rods checked, etc.
The early cast steel cranks weren't that great, and to this day I avoid all of them. The forgings have been fine, we even have one in a 505 making nearly 750hp and it's been living just fine now close to 15 years with one set of rod bearings rolled in it.......Cliff
