I was hoping to be done with 359 by now but machine shop is dicking me around. He had crank for two weeks then when it came time to cut relized it would not fit in his crank grinder. I ran the crank up to Somerset KY and will pick up tomarrow. Then it is off to the balancer to have reciprocating mass zero'd in. Here are picks of the exhuast manifold that has been Jet Hot Coated. It was done in Cast Iron Gray. I just wanted to protect it. As in another forum I answered the person who was questioning about sticking heat risers and told him to ditch it all together and now I can explain why. The heat riser was meant to do one thing and we know what that was ( I would hope) Anyway, the air temp is warmer than 50 years ago and most everyone lives in a climate where 30 degrees below zero is unheard of. If it was that cold I'm sure the Toyota would be getting the call not the old Packard. The heat riser causes restriction in the exhuast system, hence the over heating problem, and robs horse power,and thins out the dense charge of atomized fuel through heat. Then to top it off the spring will break and the valve will flop around and of course, the shafts going through cast iron leak and blow carbon on motor and fuel pump heat sheilds and make your motor sound like crap with a puffing and clicking noise. I am sure some in here will say mine don't but you are wrong. I can promise you mine don't as I have driven shaft out and then installed two grade 8 3/8 bolts copper washers and nuts. I crank em real tight. weld the end of the nut, then send out for some Jet Coat. See pic's
