any idea what rob goss has invested in time and money on developing his gen 3 program,he was going thru factory blocks at about 4 to 6 passes apiece.he has since gone to his billet blockwhich I'm sure is not a bargain piece lol.the builder probably doesn't need to make the power rob is making so I understand a production block may work for him.im old school and if you want efi and the whole works gen 3 is ok I guess but blow thru distributor engine I would still stay smallblock
