Series 1 with a Series 2 Crankshaft

I have read a post by Karma saying that some series 1 3800's were made with the lighter series 2 crankshafts. I would love to learn more about this. Here are some questions.

1. How do you know if you already have one?

2. Do these engines make the same horsepower stock as the series 1 engines with the series 1 crankshafts?

3. Is it possible to do this swap?

you can probably use the engine block casting number along with the cylinder head casting number,a combination of the 2 or one or the other.call an established 3800 building house and they should be able to tell you.

HP? dont know? might spool up a little quicker

swap? I wonder too? Might have everything to do with the engine block casting.Just like an engine block has to be matched to the timing cover to work, so too might the crank.

what happened to karmas post from last night? lol

Hey there, long time lurker and figured i pitch in on this one..... on mine the cast #'s on the crank were 2170 which is the same as the series 2. Easiest way to check i think would be to feel the flywheel, the weight for the 2170 crank is huge compared to the other like an inch short from going from 1 bolt hole to the other....the balancer weight diff. is also huge. And thanks for the site have learned alot....OH mines a "95....
