Yo;
-Speaking of "1/2 engines", AKA the 1/2 389, who out there remembers the 1/2
V-8's put into early Chevy Nova'a, if my memory is correct, say about the early
sixties?
>From my automotive machinist/engine rebuilder days, I remember they were 1/2
>of
the "small-block" casting, with the same rods, pistons, crank, etc. of the
283-to-350 Chevy family. One of my fellow machinists had a "quarter midget" & he
said these particular engines were worth their weight in gold to the racers.
Every one of them in a junk-yard was bought up in a hurry. You could put in a
steel crank, and all the hi-po rods and rod bolts common to say, a 327 or 350.
I think they also used an 8-cylinder cam, of course only using 1/2 the lobes.
You could then still use a roller cam and all kinds of trick springs,
retainers, and screw-in studs like on the V-8's, but at 1/2 the cost & work. My
racer friend also said SOMETIMES "they" would cut down another 4 connecting rods
to match the rod caps & install a full set of bearings. The engine was then
re-balanced accordingly.(did I explain this last well enough?).

Re:
>>>>>>>"Actually there is a "p". A few Tempests came with the 215 aluminum
engine">>>>>>
Hmmm. _I_ sure don't remember PontiacTempests having a "215" v-8. Slant
four, "rope" driveshaft, and transaxle,........ yes. 215 v-8.......???
But hey, if that's true then which did Pontiac use ? The Olds or Buick motor ?
>>>>>>>>". also the bellhousing pattern and some of the the other engine
features were
shared amongst "p" cars so it isn't incorrect to refer to them as BPOE
afterall" >>>>>>>>>>>
Agreed, _IF_ you're talking about the "accessories" ( the transmission /
common bell housing bolt pattern coming to mind specifically ) and not the
engines themselves. Buick, Olds, and Pontiac _engines_ are distinctly
different.
>>>>>>>>>My info says Tempest slant 4 is 470lbs (yikes!).>>>>>>>>>>>>
...... You'd need _ another_ four cylinders just to pull that weight around
! .............. Hey, do all the go fast parts available for the 389 fit
in the 194 ??
>>>>>>>>"I'd agree that the 289/302 (at 460lbs) is a nice light, compact
package. In a practical sense the Ford has far greater HP potential because
of the availability and lower cost of performance goodies (at least here in
the States).">>>>>>>>>>>>>>
Definitely. Also I might add, practical from the standpoint of being more
durable ( good ol cast iron does have some inherent advantages ) and less
stressed due to another 75 to 90 inches more displacement over the 215.
Hey, has anybody put anything like a late model Nissan V-6 and 5 speed in an
Alpine ??
