Is anyone using the 3.900" stroke in a LS1?
I've seen more 370/373 (4.03"/4.05" bore, stock stroke) motors than 3.9" stroke motors. I personally prefer big bore motors, as they make more torque down low and seem to be pretty stellar up top, whereas it seems that the bigger the stroke, the lower the maximum RPM. I want a 370 or 373 myself.
well i thought a longer stroke would help TQ over the whole TQ cruve because basicly you get more leverage on "twisting" the crank. i dont see a larger bore less stroke make more tQ down low thank a smaller bore more stroke motor that both have the same ci. i see a large bore shorter stroke make more power up top cause you can spin it faster. granted you have the supporting mods to make power up top. thats why stroker motors are sweet on the street cause they have more low end grunt. this has always been my understanding. so if i am wrong some one let me know. not trying to be a jerk just want to make sure i have my **** straight.

As far as a 4.050-4.060" bore, I don't have a 6.0 block or I would do just an all bore set-up. But I'm getting an idea of how much I can spend within the next couple of months due to tax season, that's why I was wanting to know about this set-up.
if i had a 6.0 block that is what i would do just because of cost. i am a poor college student and cant spend $1g on a crank Woaa. glad i am not the only one that thought that. oh well we will see i guess
