V8 Engine choice

Mike,

You're answer is more accurate. I didn't mean to imply the LS6 was physically
bigger, just more power. The LS1 is a 345 hp. And yes, my understanding is
they both about the same size. The LS6 is a few (10-15 lbs heavier). The LS1
runs about $5k without the ECU/accessories and the LS6 runs about $7.5K. I am
planning on the LS1 for 2 reasons, first, I don't see the need for that extra
60 Hp for a SR, and cost. THe 345 is a bit big for a SR as it is.

web surfing when I was initially considering
the LS1/LS6 and it appeared
that the extra horsepower was mostly being
obtained from improvements in air
induction through the manifold into the
cylinders. Here's a quote from
Chevy's website:

" The LS6 is, more than anything, robust.
Compared with the LS1, the LS6
aluminum block, cylinder heads, camshaft and
induction systems are revised
for better breathing at high rpm. A positive
crankcase ventilation system
improves oil control during racetrack and
high-lateral-acceleration
maneuvers."

Wayne,

You are correct. There are many similarities
on the surface, but
underneath they are much different. The LS6 is
a bigger engine, 405 HP I
think!

Brian Robinson is currently working on a FWF
for (Brent?) Davie's Super
Rebel (over London, Ontario way) using I
believe the LS6? Someone correct
me
if I am wrong but I believe this is the newer
"neater" Vettte engine than
the LS1?!.

I guess you've also considered the stock GM
ecu for export vehicles with
no O2 sensor. There is a write up in Contact
magazine about a SeaBee
with lots of hours on such a setup. He kept
his engine pretty much
stock. I can look up his name if you like.
That gentleman is also in the
engine conversion business now.

While we're talking electronics and all

you
are putting a V8 in your SR as am I. The
V8 I am using is a LS1. It's
a
bit more expensive, but it is also a more
evolved engine than the old
small
block V8. The LS1 uses fuel injection and
a coil for each cylinder.
There are hundreds of other changes from
the small block V8, but those
are
two of the big ones. Subsequently, it
requires an electronic module
called
the ECU (Engine control Unit). There are
two companies that I like at
the
moment.
