Carl,
I stroked my 3.9 w/a 300 crank and used the Ford 255 pistons (cast). You'll probably have to get your cylinders honed a little and order the pistons oversized. D&D carries them, and they can probably be ordered from any Silv-o-lite distributor. I don't know if the deck hight will fork for your rods, though.

Okay, my turn. :)

For those running Rover 3.9s, what pistons are you using? I have a '89 3.9
Rover engine with a 8.13:1 comp. ratio. I would much prefer 10 to 10.5:1. What
is the best way to achieve that? There doesn't seem to be much piston
selection for this engine. Too bad. It's near perfect, short stoke of a 215
w/the bore of a 4.6. Perfect. Now, I need some compression.

TIA,

Carl F.
