I ran into this seems to be a good artical at least it made some good power .http://www.jpmagazine.com/projectbui...5/viewall.html .

 

seems about right. just remember those are gross power figures and measured at the crank
interesting read though, the zex nitrous system interested me since i was just looking at a zex nitrous system for my camaro a few minutes before i saw this haha, talk about ironic

 

With the exception of the E-brock heads, it's the same BBO build article that Mondello has been publishing for the last 30 years.

 

Other than the info on the carb that worked better for them and the intake info . Lot better numbers that car craft and hot rod on their olds build up.

 

Yeah, typically carcraft under rates Olds, one of those magazines did a big block comparison a few years back and it was a joke. they said they wanted to use as close to the same parts as possible to get an accurate comparison. So naturally most motors got Performer RPM intakes but the Olds got some lame intake, also the Buick won that shootout and strangely enough it got its heads and intake from TA performance. Also there was something about the 440 if i remember correctly, it got more cam than the others or something like that. The Olds 455 they used was a turd, it was such a bad core they had to bore it out to .060-over. Could have been a really awesome comparison if every motor was .030-over and got Performer RPM stuff all around with stock strokes and 700-800 carbs for each, but they got way off track and it was terrible...

 

Magazines...sheesh! J/k! Good read, but not much more power than I made and I don't have near the port work or cam that this engine has. Makes me wonder what I could do if I popped my heads off for a full port and got a larger cam...oh wait, this is still a street car, dang! Maybe the next one

 

what RPM did you make that at?

 

5500, and we ended the test. I should've had it pulled to 6000 to see where the HP dropped off...lesson learned. I can only claim what I saw but it was still climbing up at 5500. So either I'm making 492 or slightly more.
