Well, I checked again and the block numbers were 290 not 280.
Maybe my eye sight is starting to finally go at 41 years.
Anyone know if the 240 hp motor would have dish pistons?
I was able to look down the sparkplug hole and the motor has flat top pistons. Couldn't see any valve reliefs but didn't really have the space to see much.
Any help would be great.
Thanks, Ken
