My 71 Duster Project

Well, it has been awhile since the last update so here is the latest. I finally heard back from the new machinist and we are back in business. The new build is going to come out to $4377.35. This includes machining, balancing, assembly, parts, taxes and labor. The heads need a lot of work as well. He told me that the seats in the heads were not hardened and will need to be done. The valves are worn out. He is converting the valves from the 4 groove valve stems to the single groove lock style valve which is more durable and more commonly used today. The headwork includes new valves, stem seals, springs, locks, etc. He said that the heads were already ported. Here are some pics of the pistons, cam specs, head bolts, hardened oil pump drive shaft, roller rocker hold downs, flywheel bolts and roller lifters. I did order the Hughes 1.5 ratio roller rockers/shaft kit and received a message that they are back ordered three weeks so I will send pics of them when I get them. Thanks for all the feedback on a separate thread about those rockers. Compression ratio is going to be 9.1, but the machinist said he needed to cut the dome off the top of the piston to bring that comp ratio down as it would be sitting around 9.7 with the dome risking detonation/borderline pump gas. The cam will be fully degree'd in and pushrods will be ordered later once he assembles the heads to check lengths. He told me the build would be about 3 months due to a few motors ahead of mine and having to send the crank out to get ground and balanced. More to follow...
