Thanks Mhernandez for the info. we are well into the project. we just got the block back from the shop had them press in the new cam bearings. We are putting in a 270 cam and a double roller timimng chain. had to buy a new crank, the crank that came out was shot. will have to replace one rod. It was out of round. the rest of them were in great shape. Waiting for the heads to come back from shop and we will be ready to complete assembly and install it in his truck. Was great to get back at engine building but more than that was great to spend quality time with my grandson that was worth more than anything.
