[s-cars] How many people on this list have gone the 2.6 L route?

[djdawson2 at aol.com]

Taka,
Calvin has a beautiful '73 Firebird... and a stick car to boot.  He sent me some nice pics off list.
 
As far as the American muscle... well, I used to be the proud owner of a 69 Camaro SS with a 350 and the "rock crusher" 4 speed.  Suspension specs and parts were the same as those used on the "DZ" Z-28.  It still wasn't exactly great in the turning or stopping dept... but it did OK.  However, I sure did love the car.  I built the engine using a steel crank (4 bolt mains) and forged rods.  Threw in some guide plates and a girdle for the rockers to keep the valvetrain together, and it was an engine that turned 8krpm all the time.  It never had any failures, except the occasional valvespring.
 
I'll have a muscle car of some sort in the stable down the road.  For now, it is just fond memories.
Take care,
Dave

Calvin-
What's the redline on your 455? I wouldn't expect to see much more than 5000 rpm
out of one of those engines.

BTW, if anyone can answer this- what is the rod/stroke ratio of the C6 Z06 LS7 engine?
7.0L and 7000+ rpm redline has got to be pretty tough on that engine, especially considering
that GM has to warranty it for 100k.

What do NASCAR 358s run? They go north of 9000rpm these days, I'm assuming that's a big 
bore, short stroke engine, though.

Hap and you other guys running strokers north of 7000 rpm- I'm definitely no engine expert,
but isn't that really running on the ragged edge?

Dave- take a look at a '67-69 Camaro Z-28 with the 302 engine- they definitely have the looks and 
all the right sounds of American muscle cars but they can also turn and stop. Same with the '69-70
Boss 302 Mustangs. :-)

I will say this, though.  A Pontiac 455 (which I happen to run in my
Firebird) has a stock rod/stroke ratio of 1.57 and a piston speed of 4042
ft/min. (5750 rpm)  These engines routinely went for over 100k miles with 
crap pistons and cast cranks/rods.  The differemces I guess I could see that
might make a difference are cruising rpm is happy at 1500-2500 rpm, no need
to wind it up to 3k+ when going 75 mph and piston side loading may not be as 
bad due to the much larger bore (106mm).  However, 1.51 does strike me as a
little low....
