Re: Is it true that .....
The original truck motors are almost all 010 or 020 castings. Of the dozens I've pulled over the years, they were all 4 bolt main with high nickle. THis is why knowledgeable builders pay big bucks for them--$400. is great money --ty to get that for a late 70's to mid 80's!!! If you really want a nice hi-po small block, I would have a 010 small block rebuilt hooked up with some Vortec heads and a high torque--low rpm performance cam to match up with your application---race, cruse, haul-tow, etc. Then you can maximize the potential of carb, intake, headers. Just throwing performance crap on a stock block is like putting premium fuel into a 6 banger!! My .02---Huck
