I've got an appointment this afternoon to have my '88 Sierra put on the dyno. Last time I went it pulled 524 whp and 516 wtq. Since then, the heads have been ported/polished, new cam installed and I've been toying around with the new carb. Hopefully it should be somewhere around ~575 hp. I'll post a pic of the dyno sheet as soon as I get it

 

nice sleeper

what else you got in there?

 

With that HP it must blow the tires off when you stand on it.

 

It's got a built 454 with a turbo 400 transmission, 411 gears with a locker, edelbrock intake, lunati cam, hooker headers with full 3'' exhaust. In that pic, it's got the street tires on it. They've been replaced with BF Goodrich radial T/A's for the street and a set of Mickey Thompson drag radials for the days I take it out on the track

 

Just got back from the dyno. Anyone care to guess my new numbers while I wait for the shop to email my dyno sheet?

 

583 whp and 575 wtq

 

Close on the whp but not wtq

 

587 hp and 602 tq? ? ?

SPPD

 

Colder on the whp and way off on the tq. I wish it had pulled 602 though... under 550 for that. I don't remember the exact numbers because I was surprised they were both over 500

 

Well I finally got a copy of my dyno sheet.

Final numbers were 581 whp and 530 wtq
