I was in school to day in the bomb lift shop and got bord and only had a pencel and paper and was try ing to figure out the most stroke I could get in my small block.
I was thinking crazy,
Useing my stock 5.7L 9.025'' deck block I started doing the numbers and the biggest stroke I could get was,
I was thinking, get a 3.850 stroke crank and off center grind(.025'')it for another .050'' of stroke.
3.900" keeping the piston hight over 1" with 6.000'' rods.
I could use an easy to find off the shelf 1.000" forged piston and and have the piston .030'' below the stock deck hight . So there would be plenty of room if I needed to take .010 or 0.015 off the deck. Or add a little more stroke.
4.040'' bore X 3.900'' stroke = 395.8 cu.in.
4.030'' bore X 3.900'' stroke = 394.8 cu.in.
With grinding the block and takeing a little off the rods would I make enought room for the 3.850'' stroke crank ground to 3.900''?
If it the pistons can clear the crank with the 6'' rod in between then I shouldn't inter fear with the crank, but I might be wrong.
Any ideas on what I could do?

 

Buy a 3.875" stroke crankshaft and build a 396 like everyone else...

Why waste all that time and money on an LT1/production block?
