i decided to go out and pull the head off my other Z and have it checked before sinking any more money in the 260 head.

i haven't cleaned it yet but it looks much, much better.

now here's the part where i need some input from the rest of you. for one thing, the cam has orange paint on it. this may be nothing but i believe this engine may have been rebuilt. the other reason i think it may have been rebuilt is i noticed the pistons have a two valve relief in them. i don't remember the other 240 having that and the 260 pistons certainly don't. the only mark i found on a piston was an 'H'.

also, the cylinders look as though they have at least been honed if not bored, as there is virtually no ridge in any of them.

now if this turns out to be the case. i may very well abandon the 260 block and use the 240 from that Z. if i did that, what do i need to mix from the 260? isn't the crank longer stroke in the 260 than the 240? if i remember right, i put the 260 crank and rods in the 240 block and pistons and i should have a little screamer.

If you put the L26 crank, rods, and pistons in an L24 block, all you have is an L26.(basically)

that's kind of where i was going with that, but if that block is a better (better condition, more recently refreshed) block, i'd rather do that.
