1987 Camaro IROC-Z28: Dyno Run with Fresh 383

Just got the 383 installed and running. Unfortunately I did not have a custom chip programmed at the time; however, this served as a good before video for tuning. I have yet to get a new dyno test performed since the new chip programming. Untuned run came out with 378 rwhp. Untuned meaning it still had the stock 305 chip running this monster engine.

Specs Continued...

The custom cam I cant remember the specs but it was a big block profile on a small block cam. The specs were very similar to a 306 cam for an LT1 motor.

Oh, I also put in 1.6 Roller Rockers just to bump up the Lift a touch.

My only recommendation is to get a rev kit so that you can get that extra top end power which could save you some time in a drag race and keep you from having to shift into another gear at the traps.

Hope that helps.

Seems pretty strong.. hope it improves when you get the chip.  how much RPM are you getting from the 383?.. I will build one myself next month.

I'm getting about valve float at around 5800 - 6200 rpm. Easy fix with a rev kit.

[Artyfil]

very nice, should be able to come close to if not beat a 2010 camaro. So does it have the TPI fuel injection on it?

[sethster70]

Pretty good numbers at the wheels. The 383 I'm building should have around 450-500 to the flywheel w/o nitrous so it should do pretty good.
