Re: Whatever happened to "Bad Bascom"?
The mule car was supposedly like the car in your first picture according to an article in Nova Times a few years ago. It wasn't one of the three fastbacks. I think all three of them wound up being destroyed. Roof blew off one of them, another rolled and third, I don't know. I think Malcom Durham raced one of them.
Didn't know Dickie Harrell drag raced "Bad Bascom" either. John De advised there is a Bad Bascom clone in South Florida now.
Many people give credit to the GTO for being the first factory muscle car. That many and many more do not know about the Factory kit to put a 327/375 FI engine in the '62-'63 Nova which your last picture partly illustrates.
Thanks for the info.Comment

You may have found the problem
"however just noticed the draft tube is out of block hole."
I'm sure you know the draft tube puts a vacuum on the crankcase as air passes across the end of it while the vehicle is moving.Comment

Re: Whatever happened to "Bad Bascom"?
this is a Z-11 427 "W" engine in the car.Comment

Re: You may have found the problem
Mike, Yes on the draft tube now that you reminded me and beside the car has only been running in garage, however that problem may have been there for some time.
Thanks Alan.Comment

Re: Whatever happened to "Bad Bascom"?
Yes it is Clem. Note the 2 piece intake manifold. A valley cover like Pontiacs with only wet ports at the 4 corners, and the fuel runners as a separate piece on top. Those intakes would only bolt up to the high port Z-11 heads. There's a lot more to it, but those are the basics.

Re: Whatever happened to "Bad Bascom"?
i worked on a few Z-11 back in the 60s,and boy were those piston heavy.!!!! those blocks and the mark IV engine have the same main bearing size and spacing so you can install a mark IV 454 4" stroke crank in one of those old Z-11 and have a 467 cu in "W" engineComment

Re: Whatever happened to "Bad Bascom"?
Clem, A lot of the guys doing the nostalgic drag racing with those motors are doing just that. The MKIV mains are actually not the same size as the stock '09 crank, (.250" bigger) but they can be turned down easily. More importantly, all the bearing centers are the same, so they fit the saddles just fine and the rods line up with the bores just right. Most people also turn down the front snout as well, since the '09 snout is the same as SB. That allows the use of the stock timing cover with the small hole.
Those old '09 pistons weigh almost 2 pounds ea.! (28.5ounces)And they're aysmetrically balanced (off center). One good fix is to use the MKIV rods (same length as the 348 rods), .125" longer, then shave off .125 from the heavy side of the piston at the deck. (or less if you want to increase CR). Result: stronger rods, longer length=more torque, and a better balanced piston. Not so much handshaking between the skirts and the walls.
Overboring an '09 will not measurably increase CR since the combustion chamber is mainly in the unswept wedge at the top of the bore, below the deck. The heads have no real combustion chamber other than about 10-13cc around the valves.
I still think Zora should have let the Corvette have a big block 2 years earlier! It's only 50lbs heavier than a small block (although a little further forward)...............and it fits like a glove! He had complete charge of the Z-11 development. Wish he was still around to ask him "why not?".Comment

Re: Whatever happened to "Bad Bascom"?
there is super market chain owner in dubois pa who has 3 Z-11s,2 completely stock and dave strickler "old reliable". a friend harwood dorman who later owned a new 67 L-89 corvette first corvette was a 57 with a 409 engine. the Z-11s cold air type intake system was later used in the 67 Z-28. with the combustion chamber in the cylinder and not in the head caused heating problems when you tried to used the "W" wngine for circle track racing. that was a weird design with the flat head surface like a cummins diesel but there was no shrouding of the valvesComment

Re: Whatever happened to "Bad Bascom"?
That would be Don Fezzel in DuBois. Last spring he bought his FOURTH Z-11 ! By coincidence, last year I bought a complete 409 that was in a '57 Corvette. I'm sure it wasn't the same car you mentioned because it was never on the road.
In design testing, the engineers seemed to improve the water flow through the head by moving the water pump outlets to the outside edge of the head, but you're right, those "W"s seem to build up a heat soak with sustained high speed operation that overcomes the cooling system. IMO the exhaust port is the biggest limiting factor in extracting power from the "W" design.Comment
