Freightrain Posted 15 hours ago Author Share Posted 15 hours ago "dark grey". Looks like a std grey primer color. Not dark at all. I knew it was likely not right. Only bought one can. Mack is definitely darker. I am leaning towards grey instead of maxidyne gold. The gold I bought for the transmission last year was horrible. 300 were gold, 300+ were grey.

davehummell Posted 15 hours ago Share Posted 15 hours ago Larry don't feel too bad I have $2500.00 in my Shilo Sharps 45/70 and $2000.00 in my old Winchester model 94 38/55 and another $500.00 in a Uberti 45 colt rifle and probably another $ 2000.00 in bullet casting and loading tooling just to try hitting metal plate targets and every time I do the shoot I pay $10.00 bucks plus about 86 miles round trip in my $48,000.00 pickup and I'm the guy that brings home the targets and repairs them. I can just imagine how much it cost to run your drag car.

Freightrain Posted 15 hours ago Author Share Posted 15 hours ago Once the car is running,it isn't that bad. $60 to enter, $40 in race fuel a day. Diesel fuel to get there($100?). Building it was where it hurts. $20k motor, $10k transmission, etc. Luckily that stuff last a longggggg time. Oh, ya forgot to mention, Mack valve stem seals $14 EACH!!! Times 12.

Freightrain Posted 11 minutes ago Author Share Posted 11 minutes ago Ok, anyone have the part number for the crank hub for a 673! Not the 300, but a END673. I have to use the hub from my 673 motor like I did for the 237 to line up the belts. I noticed the ID is kinda scored and actually worn on one side. I would like to replace it if possible. The one for the 300 is longer by about 3/4" and has a pilot sticking out for the balancer to register. Unlike the 673 which has a small hub that registers in the counter bore shown. This all shortens the length for the balancer to clear the front cross member. Quote Larry 1959 B61 Liv'n Large......................
