The dyno sheet shows 377 hp and that translates to about 454 hp at the flywheel.  That is more than I expected.  The torque is pretty good too.

I noticed the time of the last post at 4am.  Believe me I was not awake at 4am.

Denial is a sure sign that you have a problem.

Charlie, this must be a streetable engine you are running.. those peak numbers for HP and Torque are not that high up in the RPM band it looks like to me. What kind of cam specs do you have (if you want to share)?

that's great Charlie, I love the way it holds the power all the way past 6500.  I like the 60-61 comet in the back ground! the truck looks great! keep up the great work, and good luck!

Daniel, you have it quite right.  Turbo cams are quite mild compared to naturally aspirated race cams.  The lift is still important, but the overlap is decreased substantially.  The lobe separation on the Brick engine was 108* while the turbo separation is at 114*.  Ramp speeds and other cam lingo is a little above my head, but reducing the overlap starts exhaust scavenge earlier and helps keep the charge in the combustion chamber on the intake stroke.  The attachment below is the cam card which shows all the specs.

Yalincoln, thanks for the comment.  The 61 Comet was going well and my intent was to run in a gas coupe class until a friend of mine rolled up the driveway with the GMC mini pickup on a trailer and said "It's all yours".When I first started to go landspeed racing 15 years ago I had a plan A, B, and C.  The Brick was plan A and I had hoped to reach 125 mph and walk before I ran, and we walked pretty good.  Plan B was the 61 Comet and I had hoped to advance to 150 mph.  Plan C was always to run a GMC mini truck for the very best aerodynamics available and get back in the pickup divisions to run 200 mph.Once the Brick was retired I started to work on the Comet and had a good start with a Mustang II front end and a 9" rear.  I had fitted the Y-Block and a T-5 in the Comet when the GMC arrived.  The Comet immediately went on the back burner and I proceeded with plan "C".  It is yet to be seen if I go from walking to running but I have faith that the 339" stroker that Tim is assembling now will hold together until I can figure out how to make enough power to reach my goals.  The 258" motor is a great place to get started with this project and the 339" engine will be set in place after the Bonneville Speedweek in August. By the way, I bumped the BonnevilleComet thread just in case anyone wanted to see the old posts about it, and you were the last one to post on it!  The last couple of pages are off topic, but the pictures were back on page 9.

thanks Charlie, I thought I remember the car, but you know how it is with us old guys, memory is not what it used to be. I still love the comet.
