Bore and Stroke ?

well that would be .1 up .1 down...so .2 total...and yah i might think about the 3500 and then getting the TCE trigger. i really want a very clean install...but its still just a musing

Bah.. pick up a 3500, bore it .030 and use SBC 305 pistons, offset grind the crank +.25" and have a 3800..

Desktop dyno dosen't show much of a HP increase, just more torque.

You can only offset grind the crank to ~.100 increase, you have to divide the .250 by 2 giving .1125 and then clean up the crank after the offset which will net about a .100 offset.

Use a 3500 crank and have the large rod bearings offset ground down to the size of 3400 bearings. You can get them in the forged variety too.

Ok so tell me if my thinking is correct...
stock bore size and stroke size is
3.62 " bore
3.31 stroke right

so that pretty much nets a 3.35 liter or 204 cu in right...the 3400
so then a 3.6 stroke on a 3.65 (.030 over) is a 3.7l or 224 cu in
then a 3.8 in stroke is a 3.9l does that sound about right?

I would think about .040 over, but that just seems like too much...but i dont think the outer limits of the 3400 have been set have they??? maybe .040 is ok?

Yes to answer any ?s i do have a stroker idea in the plans...I like the idea of a 3.5/6/7/8/9 stroker...but i would like to stay within the confines of reliable(haha) and ease of finding a machine shop that will build up the crank and grind it for me...this would be a stock 3400 crank that would be stroked and offset ground, then prob some manley or scat rods machined and then block clearancing when i get all that back. then i would take it to my local shop with all that and have it balanced...that way its a monster of a v6 hehe...
