you're taking your engine to a machine shop and don't think they will have the stuff you need?

 

No. I have to have my keyed hub for balancing and my main girdle for him to torque/check/main honeing.

 

So why did you aske the question, why part numbers were different for the longer rods?

 

I think the question I had for you was why are there different cranks for the size of the rod, I know the pistons are not the same.

 

Just ordered my Keyed Hub from Jegs. It looks like a nice piece. Three holes tapped for the balancer and a keyway so you don't have to beat the hell out of it to get it on the crank.

 

u know if u put the hub in some hot water for a while and let it heat up good it will go on easier. should not be beatin on the balancer.

 

dang and i wasnt going to post on this thread. lol. so how much play in the bearing. if the motor is going to be balanced i would think u would want a tight fit.

 

Good question Crab. It has to be installed before balancing? Maybe I should let my machinist handle it. I'll ask him tomorrow how to handle a loose fitting pilot bearing. And I am tired of messing with that dam keyless hub. When I first removed it I broke four pullers and heated it up until the crank gasket melted. Then I figured out about the center pin method. It is just too tight. The last time i installed it I hammered on it for about a half hour before it seated on the crank. Then I had to grind it so the balancer would go on! Lesson learned. Plus now I'm thinking about converting to a big blower on top!

 

then you're going to want different pistons to lower the compression...and i definitely wouldn't trust the chinese crap you've been putting in your motor if you're going with a blower. but whatever you think you need to do

 

Ya, thanks hammer. You can also change compression by heads or thick gaskets. My car is a street emissions regulated car, I don't need billet steel stuff! And all the American made stuff is too expensive for me, that's for the rich guys. But I sure do like the new style blowers they got out now!
