Try and find a good deal on a running truck motor as they're the deal especially if the 4https://www.yenko.net/ubbthreads/imag...emlins/eek.gif9 look is more what you're after!.

John,
Be wary of truck blocks unless you're planning on building a blower motor. They have 2 fly-cut wedges removed from the combustion chamber to lower compression to about 7.5. You can't make that up with different pistons.
There are some ways to recognize a truck motor externally (if it's mostly complete). The intake will be a very low-rise with extra threaded bosses near the front to mount an air brake pump. The dist. is one with a govenor and has a wide metal band around the base. The water pump is huge and the valve covers will have the 4-wire loom tacked at the middle, rather than the rear.
Good luck.

Verne,

Unlike the later MK1V passenger and truck engines being different from each other, w/ the W motors can't you mount external passenger car parts like intakes, waterpumps etc to the truck engines even though they're lower in performance internally?.

If you went to the Impala auction earlier in the year you would have had your chance to buy every "Impala" truck 409 you could get your hand on.

Yep! You can bolt any passenger car stuff (including Z-11 if you wanted to) onto a truck block. You're still dealing with low compression and there's NO way around it unless you weld up the fly-cut wedges.
Remember, W motors have flat head surfaces, ie: no combustion chambers in the heads (except for 13cc around the valves). The combustion chamber is in the block above the cylinder bore. IT's a 16deg wedge between the top of the piston and the head.

Thanks Verne!.

I yanked a good running '65 XX suffix W-motor out of a dumptruck a few years ago for my '49 Stude pickup project and like I think Hep may be too, am not as concerned about high performance as I am for simply running a W-motor under the hood!.
