Blazer is really done. Last pictures while she is still mine.

OK, going through the numbers you all posted to find the winner. Hang tight. Numbers coming in just a moment.
 
Hey Kert, you got a installed pic of the valve covers?
 
OK, so there are gona be two winners. One was closer on HP and one closer on Torque. Both are getting a $50 gift cert.

Z71 paramedic wins on the HP number.
'80 427 wins on the Torque number.

You guys should call Tracy and she'll set up the credit/gift cert. 712-472-0200

Official numbers, 256.71 HP and 358.76 ft. lbs. torque.

I think at the flywheel the motor itself would be close to 500/500. Just guesstimating that though.

Some things to keep in mind if you didn't go through the build thread and look at everything.

SM465 is big heavy parts. Two transfer cases to spin. Driveshaft weighs some where around 70lbs. 14BFF is a heavy carrier and this one has an orb in it which is just more weight. Rims/tires got to be around 175ish each.

Engine accessories will also pull down the numbers. Alternator, water pump, power steering and a york compressor. On a side note the York would not disengage the whole time it was on the dyno. Ended up with an airline disconnected.

Am I disappointed, No. The seat of the pants dyno numbers are all I care about and like I said, I was there for the tune and we accomplished that.
