Buick 300 crank to SD1 3.5
Hi,
I tried to read the whole articles of it, but i'm not to good in english, so there is one thing i don't understand. Especially the connecting rods, and pistons. Can i use the old ones, or i have to use different (couse the longer stroke). Thanx |

Connecting rods: Yes, used is good. Actually really good. They are forged units and nice.
Pistons: NO. You need new ones to make up the difference in stroke. Total deckheight (center of the crank to the block top): ≈227.5 mm Connecting rod length (center to center): 143.75 mm Buick 300 stroke: 86.36 mm/2 = 43.18 mm 143.75 + 43.18 = 186.93 ≈227.5 - 186.93 ≈ 40.5 mm That is the piston height you need. ≈ 40.5 mm (1.59 in.) compression height for the piston. |
