Re: inline 6

I'm interested in the rebuild you did on the crab. Does it still have the standard issue of legs and claws or did you modify that?

Look for parts for a 1969 Chevy C-10 pickup. They fit just right.

Hey BubbaHemi, don't pay Chris any mind, he's just messin with ya. I have a carb redo coming up this fall too.
When you put it back together make sure there isn't anything wrong that can re-break your piston and rod. Crank it over with water to the motor and the plugs out to make sure you don't get water to the cylinders. Water can be your culprit if there's a cooling system problem.

Re: inline 6

,Don't try it . Mercruiser tried using the 292 block back when the 292 was a current engine and had way too many failures with them . They went back to the 250 CI GM engine until the v8's stated coming on the scene . On paper it was a good idea with all the torque of a 292 but the long stroke of that engine puts way to stress on the cylinder bores and connecting rods . Whereas the 250CI engine was a better bore and stroke combination for marine use
