No. The Corvette with the mount bolted across the front of the engine had a 
three point mount.
 TC> Possibly, unless the fronts were mounted really wide, like the

Yes, because of the suspension and the placement of the engine in the bay.

Not likly.  283's were hard pressed to make it to a 4" bore.  That'd be an 
1/8" to bore out.  You'd need a perfectly cast block. I remember a lot of 
them going to 292, but hardly any 301's from 283's.  Some, but not many, and 
those weren't streetable due to the heat warping the thin cylinder walls.
 TC> And did the guy put the '55 engine in a 60's Chevy II? It's now
 TC> apparent that he possibly could. But was it a 265? If it has an oil
 TC> filter on the LR of the block it wasn't a 265, but must be a 283.
Uhhh, yes it could be a 265, 1956 or 1957 vintage.  If it's got an oil filter 
mount cast in the block, there's only one or two ways to tell.  A quicky 
would be to look at the cast date on the bellhousing, passenger side.  If you 
can decipher it (I can * ), you could tell what year the block was cast.  A 
number six would make it a 56 block, if it didn't have the now familiar motor 
mount bolt holes on the underside.
*Example: Casting code is A236,  January 23, 1956, 66, 76, 86, 96...
If it's a number seven and no motor mount holes underneath, its a toss up and 
you'll have to measure the bore, 3.75 for the 265, 3.875 for the 283. There's 
also a little known casting difference in the front of the block, but if 
memory serves, it just serves to distinguish 283's from 327's...
 TC>  I still say no, a 265 can't be bored to 4", due to the cylinder
 TC> wall thickness.
You'd be pretty near correct there.
 TC> Let's hear from the guy who did it, (I forget who that was.....) Oh
 TC> well, thanks guys for the discussion. I'm goin on vacation.... Tom

Great, be looking for you on the boulevard.
