OK. Here's what it is. Stock 4-bolt bottom end with stock crank rods and
pistons. Crane solid lifter cam, roller rockers on 7/16" screwed in studs, and
dual "Z-28" springs. I am running a mechanical Carter NASCAR pump, after-market
3/8" id fuel line front to back, and stock HEI. I'm running a 3.08 gear. Last
summer at Maxton I lifted at 6200 to be sure not to blow the motor. With the
gearing I had, that gave me a bit over 140 and I was pretty happy, considering
what I was running.
Now I've added a good port job to the 882 heads, increased from the 600
Edelbrock (AFB) to an 800 on Victor Jr. Increased headers from small cheapos
to Hooker Comps with 1 3/4 primaries. Previously, on this list, the consensus
of opinion was that my stock bottom end (piston speed) would limit me to around
to six thousand. There is no doubt in my mind that the breathing will now
allow this motor to rev to 7,500 or more, but I prefer not to leave pieces of
pistons, rods and crank all along the track. $ $ $ $ $ If we "re-visit" the
piston speed and max RPM issue and you guys convince me that I can rev higher
without danger of doing this, I'll run it higher on Memorial Day. Any
comments??
I've increased my overall drive ratio (actually gone to my taller tires - 24.5"
up to 28") and expect to pull the taller tires to the same 6250 red line with
the appropriate increase in speed. If I go into the block to change to some
good rods so I can raise my red line, then I might as well add some good
forged pistons so I can actually use my nitrous, and then a better crank, and
then ...... Well, y'all know how it goes.
Some of you will remember, from way back, that this car is what I nicknamed my
"transition car". My true passion is nostalgia cars with old hemis, and I was
building, amongst others, a hemi-powered 1923 Dodge roadster that was
progressing really, really slow. I had that incurable need for speed, and
decided to put this Camaro on the track just to have something to run while I
took my time building the old hemi car. I have also been told that dollar for
dollar, I'd be hard pressed to get the same performance out of those old hemis
that I could get out of this small block bow tie, but hey, that's where my
heart is. They say "You can never go back.", but that's just what I'm doing,
and when I open the hood, it's going to say "Firepower" and have dual fours!

"stock style" hard lines. My '73 Corvette "short tracker" gets
along real well with a similar set-up, which are 3/8 ID hard
lines ( a Holley will "store" more fuel than an Edelbrock) But
hey, how hard is it to run a larger line just for insurance?
Dave asked the question I wanted to; Why such a low red
line??? I assume your new heads have (at least) larger, dual
valve springs, and at least 2.02 intakes.... If so, a larger
bump-stick might be the way to go. Even a 2-bolt main SBC will
take more than 6250 rpm.....
