Default crank offset grind?

Anyone ever offset grind a crank to get more stroke, if so how much stroke were you able to add or limits did you go to?

Depends on what bearing sizes are available as to how far you can go. Pick a top notch crank grinder, that can properly index the crank, and get the radius correct. Be aware the pistons already stand a little proud of the deck.

I have been thinking along the same lines for my next build. I look forward to some good info on this thread, and hope it stays on topic.

iirc mine were .015-.020 out of the block, stock shortblock. I am also running a .035 head gasket. There is room for more stroke.

My 2 liter engine has an offset grind on the crank, with Honda Pistons and rods.
These are the pistons http://www.jepistons.com/Products/185918.aspx
I'm not sure of the rods. Sadly I don't have any more details about the engine other than the rods are made by pauter.
If anybody wants to, they could probably get the details from Ric Stevens in TX.

One of the things I plan for my next B6 build is to see what the limits of the machining are for that block. I hope to start it sometime this year.

Is anyone else just absolutely floored at the cost of pistons for these motors??

We ordered a set of forged pistons couple years ago for a small block chevy build (8, to be exact) for under $500.00!

You realize you're comparing the cost of parts for the most commonly built motor vs one that's probably gets a couple hundred builds a year if that.

do you know off hand if they were custom made rods or a set of OEM\aftermarket premade rods?
