Also if it's a blower motor,check your pully bolts on the front of the crank and make sure one is not interfearing on the timing cover.Check the same on the blower. everyones always so quick to pass judgement. When you spend nearly $4500 in parts, and pay an engine shop $1500 for machine work, assembly, clearancing, etc. you tend to get a little jumpy when something's not right. If I'm going to spend $6000 on an engine build, that's something I don't want to do twice. I know everyone is human and we all make mistakes, but you have to wonder, if they missed something simple, what else did they miss? (that is, unless it was your fault because you dropped a nut down the intake or whatever) Photobucket sucks

I may need some educating here but if something was on top of any piston, wouldn't it only turn over 180 =/- a few degrees since every piston comes up twice ?? Sames goes for a rod bolt since they also make 2 passes (2 up/2 down) in 360 degrees. Someone clear that up for me. To clear this up for me, are you turning the engine around 180 degrees and calling that 360 since technically your balancer has made a 360 degree revolution but the engine has only completed one cycle?

I've seen Jason Line make mistakes (very few) and he get's it figured out. Will soon find out. Snap your neck, mega G-force launch, is all I want!

Glad to see it wasnt your fault, he'll fix you up, he doesnt want to have anything bad said about him. Its probably like Chuck said that the crank is crashing the pick up

It's nice if he fixes it - but who pays you for your wasted time and trouble? When it's fixed he owes you a favor, money, or a discount on future work (if he's smart that will be his choice) Boffin Emeritus

That's interesting... That gear on those units are very beefy. Seems inconceivable, but? One of the necessary steps to set up a Milodon is to remove the factory timing cover pins in the block, set the "lash" between the gears and redrill the block to accept the oversize pins. I would imagine that if this wasn't done(or done improperly) that you could have a problem. Possibily some debris wound up wedging itself between the gears?? All speculation without actually seeing it. Keep us posted. MB

The engine builder put it together and the gear did not set flush against the crank. The mopar 4" stroker crank has an outside radius and the crank gear was not machined with a radius. It kept the gear 3/16" from flush against the crank. I found out when my pulleys would not line up when installed. What im thinking is if its got a stroker crank with an outside radius and the gear was installed and just tapped back with out checking to see if it was flush, then when the balancer was installed it broke the gear by forcing it onto the radius......My ....Phill
