Subject: 331 Camshaft

I just bought a new camshaft from Hot Heads for my C300.  I was wondering
if
anyone has any experience with their camshafts and if any changes need to
be
made to the valvetrain.  The grind number is "ST-1" and I have a spec
sheet
on the lift, duration etc.  I was also wondering what effect on
performance
that it will have over the standard cam that came with the car.  I would
list the specs but I don't know what numbers on the sheet  to list.  Any
information would be helpful.

Hardy, The cam list should show the lift in inches, the duration of the
cam, 
overlap duration, etc. Post all the numbers on the sheet with the
description 
heading and the rest of the experts can then decipher where to go from
there.

Several people on the list asked me to post all the numbers on my camshaft
spec sheet.  I will list them below

Valve Lift:  (intake) .450"   (exhaust) .450"    (r.a.r.)  1.5
.050" Duration (intake)   226  Duration @ .018" (intake)  254
                     (exhaust) 226                          (exhaust) 254

Lobe Centerline (intake) 106		Lobe Seperation 110.0
Lobe Centerline (exhaust) 114		Advanced 4.0

Valve Timing @ (intake)     Open 7.0 BTC     Close 39.0 ABC
.050" Lifter Rise (exhaust)  Open 47.0 BBC   Close -1.0 ATC

Cold Lash (intake) .016"  (exhaust) .018"

Recommended Spring Pressure:  Seat 100-110   Open 260-270

Hope this will help figure everything out.  I am leaving for Talladega in
the morning and will be back next Monday to check my emails.  That is if I
don't get blown away or drowned along with 50,000 other people camping out
in the fields around Talladega.  If anyone is at Talladega come by West
Campgound A spot 312 & 351 and say hello.  Might even have a few cold ones
for you.

Hardy
