<VV> otto 20 cam vs. clarks 270 cam

[Roger Gault]

Years ago I replaced the stock 140 cam with an OT20 during a complete
rebuild.  Frankly, I didn't notice anything that couldn't be attributed to
the rebuild itself.  No cool sounding idle, no huge extra kick in the rear -
no real suprise, I wasn't expecting much.  None of these cams is going to
make a huge difference; the GM engineers weren't idiots.  The problems with
the GM cams are more related to valve float, etc. than they are to overall
breathing.  The OT30 would probably give you a lopier idle, but at the cost
of some low end - not a peachy idea in traffic.

If you want a big improvement you're going to have to do something more
serious, like fix the exhaust system by going to some angle tube heads or go
with a 3.1L conversion.

Low buck approach is 3.55:1 rear end, little tires, and earplugs for the
highway.

Or, you could get really stupid like me.  My 3.6L stroker is in the car and
being hooked up.  Pretty soon I have to get up nerve to try to start it.

I'm getting ready to order my cam from clarks,  the otto 20 and the clarks
270 seem very similar, can anyone give me a rundown on how they compare
performance wise?  I'm looking for a mean street machine, but want to
maintain driveablity.  I would like to hear a little bit of a lopey idle,
but reliability and driveability is important to me.  This will be a weekend
driver, not a racer or every day driver.
