I have a friend that runs a Dart with a 440 in it runs 10.70, His motor has 750 runs on it and the guy that sold him the car had 300 runs on this motor . So I asked him who built the motor. He said the guy died , I said yea he starved to death waiting for you to have the motor freshened So how many runs you got on your motor and who built it If I get 250 runs on a motor I think I did good Bud www.wildcar-go.itgo.com 64 DODGE 60' 1.433, 1/8 6.38 at 107.4, 1/4 10.08 at 132.02 foot brake, leaf springs

I have about 250 passes on my W-9 now and its still running the same ET as it did new. I take a leak down reading when its new for a reference then a couple times a year take another reading... if its not dropping its still doing good. I would say he's doing REAL GOOD with that number of passes but I would at least check the spring pressures

Yes it has slowed about 2 tenths over the years, but no smoke. he don't turn it real a hard maybe 6400, but I still think it is a good build with over 1000 runs. I told him I wan't to be there when he tares it down . It's just a 446 with a set of 906s a 590 MP cam and a m1 with a dominator.

I run an off-set ground 413 crank w/stock caps and studs and have been 7500 rpm`s and am now changing my generic valve springs out for some spintron tool room iskys to see if it runs better since my springs measured pretty low. 72 Dart 470 n/a BB stroker street car `THUMPER`...Check me out on FB Dominic Thumper for videos and lots of carb pics......760-900-3895.....

Rods will be replaced probably pistons and rings and bearing, a bit more compression and cam as I still have some left on the table there. New springs at 50 runs.

Ran it for several hundred passes over a couple of years with no power loss or breakage. We were using a heavy 12:5 TRW slug with stock crank and rods. Finally the small end of one of the rods gave up...go figure!

About 75-100 runs in the Coronet with hard 5-6K street miles. Then over in the Dakota for 3 seasons, probably a easy 200+ runs. Now sits between the frame rails of a Mud racer, with two seasons, with the original bearings etc. The guy who has it now picked it off a good friend, he came to me and I pulled the pan and looked it over, we put the pan right back on it. No bearing changes. Eagle Crank, and Off shore H-beam rods, and Probe pistons. Stock oiling system, stock main caps, and arp bolts through out. I built the engine in "04".

I am going to error on the side of caution with the rods. Pistons will get swapped for more compression, otherwise it would be a simple freshen up. Probably more cam on the next one as well as some was left on the table. I spin it to 8400rpm so not worth the risk IMO. I would rather spend a few $$ to make sure all is well than take the chance of loosing a motor in the traps at 170 Ted the springs are not a huge issue for me.
