>I was thinking about stroking my block to 393 or 408 as a winter
I'd get the 393 since you'll save money. The only non-stock part is the
crank. You use stock 351W rods and dished 302 pistons.

They are who I bought my crank from. Check this out...

Well there are 3 different deck heights for the 351 (not counting the
Cleveland) 9.48" for '69, 9.503" for '70+, and 9.20" for the SVO blocks.
, regarding the 69-70 Windsor the blocks are different, but the heads
were the same. It's up to you if you want to worry about the .023"
difference between the 69 block and the more numerous 70+ blocks. It could
matter when it comes to assembled height of the crank/rod/piston and
clearance to the valves and how wild a cam you run and rocker ratio.
The other thing that had to be done to the bottom end was some slight
notching, but also a few strategically placed outward "dents" in the oil pan
for clearance. Make sure you mock it up before final assembly to make sure

Yes! I'm using a D9 block with C0OE heads. Everything else that bolted onto
the original '69 block will bolt on. In fact I swapped a few parts off the
C6 289 that was in my Ranchero onto the D9 block. They didn't stay there
long, but they all worked fine. You will HAVE to have it balanced or the
engine WILL scatter itself in short order. You should have seen the flywheel
before we dropped the motor in. I've never seen so much weight on one side
of a flywheel before. sheesh!
