1985 Ford F-150
Country Boys Can Survive
Alright we finally got us a 410 and its been expensive so far. We paid 550 bucks to get it in the first place along with another 390 and the guy told us that he "rebuilt" the 410 with new rings and bearings and honed the block. It might be an original 410 and it might not be cause the block shares the same casting number as a 390 so were not sure. We also double checked the crank number and it has a 1u so that checks out fine. We got it home and had it sittin in the garage for a couple weeks then we decided to take a closer look at it. We found that he put all the rods and pistons in backwards and in the wrong order. I first noticed they were in backwards when we looked at it at the guys house and saw the little divots the are supposed to face towards the front of the motor were facing toward the rear. After dad saw that he said lets go ahead and look at the bearings. We get one of the rod bearings off and its down to the copper so then we check the mains and its the same thing so we tear it all down and get to the rear main and he either reused the old one or he trashed the new one. The side rubbers were all mushroomed out and there werent any nails in there also the two half circle pieces were extremly brittle and broke in half when we tried to get em out. So we took it to the machine shop and had em look at it and the guy there put a ring in the cylinder to check the gap and it was huge so we had em bore it .030 over and clean out all the oil passages and stuff along with redoin some heads we had done by the moron who did all the machine work on the 390 that was in the 76. The good machine shop told us that he had to replace every valve in em cause the other guy ground em down to nothin. We also had em get the broke off tap out of the intake manifold while they were at it. Also the crank needed to be turned .010 so we had em do that too. We got a 268/272 comp cam, arp rod bolts, new lifters, new oil pump, new pistons and rings, and were gonna re use the double roller timing chain that we put on the 390 since it dont hardly have 3,000 miles on it. We also had to try to find an externally balanced flywheel and that was another 170 bucks off ebay. Were gonna use the edelbrock intake off the 390 and try to get one of our carbs to work we have two edelbrocks and two carters to choose from so if any of those dont work then im gonna try a holly. All said and done the machine work come to 1,500 bucks and total including the motor purchase itself is about 2,100 bucks.
Heres a couple pics of after we got all the stuff yesterday.
Thats the intake that I broke the tap off in the thermostat hole.
Thats the crank.
The guy painted the block yellow and it didnt come off when the machine shop dipped it so I gotta paint over it.
