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

[calvinlc at earthlink.net]

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....

Also... in my response, I said feet per second... when talking piston speed.
It should have been feet per minute.

Didn't you and your wife have a child recently? If so, I would not proceed
unless that child's college education is paid for.

There are 2 basic options when you go the stroker route. 2.5 with the 92.8
Eurovan crank and 83 mm pistons and 2.6 with the 95.5 crank and 83 mm
pistons
and the Eurovan block. IMO the 2.6 option puts too much side loading on the
pistons and the rings because of the extra stroke and side dispacement from
the
longer throw. You also have an issue with the speed at which the pistons
travel
within the cylinder and those inherent problems. Dave Jones would have
severely limited my red line to under 7000 rpms if I had chusen the 2.6
route.
With
my current 2.5 he has imposed nothing other than a very strict break-in.

Your other requirements would be custom tuned SW/EMS, tubular EM, 3 1/2" DP,
FMIC, Big injectors, 044 fuel pump with -8 lines, custom turbo ntake, Big
Bore
throttle body, and Big turbo to name a few. As for the turbo, the GT 35R is
my personal choice. In the stock 2.2 litre AAN, the GT 30R is a great option
with a tubular EM. In the 2.5 litre stroker, you'd be running out of push
over
about 5500 rpms with the 30R.
