Okay, Jay's testing shows the CJ and PI to be fairly close on all tests.....

Response to weight difference

These are average hp numbers.

-------------------------------------CJ-----PI
428 Thunderbird motor----------309.6---302.7
410 hp 428CJ--------------------321.9---317.2
390 Stroker----------------------402.9---400.6
390 Stoker-internally ported----406.7---404.7
427 Side oiler-internally ported-446.7---436.2

The CJ intake has an advantage, but it's not huge. The weights according to the book are 82 pounds for the CJ and 27 pounds for the PI.

I'm surprised the ported CJ pulled away from the ported PI on the 427 Side Oiler engine, but other than that it's real close.

Oh yeah, anybody that doesn't have the book, you should get the book. It's great.

JMO,

paulie
