You have one chance to do this right. Learning curves are 90 degrees and margins of error are near zero. This is why I offer classes.
I always stick with the M# designation that the vehicle came with, unless its a crazy project with no budget or time constraints.

Jake,
I am sorry perhaps I was not clear enough, I was referring to the strength of the 3.4 crankshaft because I was considering going to the 3.8 Nickies with the forged rods and was not sure if the crank would be the weak point.
Regarding the learning curve, I have assembled a few aluminum (Italian and old VW) engines but by no means are an engine expert, but I am planning to attend your M96/97 rebuilt class, hopefully before this years end, thank you for your comments!
