BBC

The factory ZL1 blocks have two vertical ribs above where the timing cover
bolts on. The cast iron blocks do not have them.  Page 82 of Hot Rod
performance series 'ENGINES' that is on sale now has an article titled 'ZL1
returns'
The new ZL1 block has the ribs also so you can see what I'm talking about.

	I have an old Aluminum BBC in my cobra project, it looks like a
varient
	from the Chevy molds, not a vintage (early 80's), but I had heard
that
	someone was doing them after chevy gave up on the racing but not
really
	sure on the history. It's not a donovan, they have a REALLY nice
block, now
	up to 700Ci in a super high deck block (raised cam too). If anyone
know of
	how to tell who made this block let me know! It has no marks or
numbers as
	it was completely polished before I scavanged it. Also the 430 in
the CanAm
	cars was a really hot motor, it was the sleevless motor with a 348
	crankshaft, big bores, dinky stroke as the bores were huge. The 348
crank
	was shorter stroke then the nice 396/427. Yes you can fit a 348 or a
409
	crank in a BBC just need  bearing spacers and I think that was it.
Just for
	nostalga, I got the ZL-1 cam from Skogins-Dicky just to get a feel
for what
	was once a very nice package ;-)
