<strong>Hi guys,
What size stroke crank are you running.
What Bore size...
What is the largest stroke crank you have seen used?
Cheers,

4.060 bore = 6.0 LQ4 block
4.125 = most stroke I have heard, after a while too much is too much.

The biggest motor I have seen is 4.125 Bore, 4.125 Stroke. I agree with PSJ you do get to the point of diminishing returns aound 434/6 max even at this size you are beginning to push the limits of reliability and block integrity of the aluminum block.

Re: Stroker Poll I'll be running a 4.03" bore and 4.125" stroke.
There may be some awesome heads out within the next year or two from AFR. With a custom intake and these heads I think these strokers will be able to be twisted up pretty high.
I was thinking of going with a longer stroke but, decided to wait and see what type of heads and intakes develop. If I ever want to upgrade this motor, that I don't even have yet <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> , then I'll go with new heads, intake, and throw a solid roller in there so it can be spun a little harder. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> I'd be scared of putting too big a stroke in for fear of a rod hanging out the side of the block. <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />
I think in the next year or two we're going to see some serious N/A LS1's, especially with new head development. <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Re: Stroker Poll I have a Lunati 4.125" crank, with a 4.1" bore resleeved ARE LS1 block. As for the largest, Walker from the Corvetteforum had MTI build him a 449ci, which is a 4.250" stroke and 4.100" bore I believe.
Personally I love the extra stroke to give you the low rpm torque that sets you back in your seat real hard all the way from 2000rpm to 6800rpm.

Re: Stroker Poll Yes, the longest stoke crank offered for the LS1 is 4.25". I don't believe anything longer would clear the skirt of the block. Theoretically with a C5-R block you could build a 462 cu in engine (4.160" bore X 4.25 stroke)
My stats are 4.030" bore (iron block) with 4.00" stroke.
