I love how everyone uses that article to show what a 383 can do , the problem is the HP claims are BOGUS , the dyno used was known to give inflated numbers and eventually they admitted their correction factors were the cause .
This reminds me of a posting earlier about what is a happy dyno, what makes it happy?
Well, at least there printing corrections.
Also, often, the write ups have a base pull and a after parts added pull so you can see a difference. Since there (The rags) are the only ones out there doing anything like this, what else does anyone have to go on?
Have you a build up like theres? Can you do a article? With pictures?
Hell, I'd love to see it and I'm sure the OE poster would as well. I have a 400 on deck to do! Whatcha got John?
