Default How does this happen?

A forum member sent me a PM......I asked if I could post this to try to get some answers as to how this happens. They said "sure go ahead"...

SO I ask how does this happen?

I know of 2 motors:

1. 383 CFI's, both have the Xram. One motor has these heads
Dart Pro 1 180cc/64cc- 268XFIHR13 Cam

2. The other
AFR 195 cc / 65cc - 280XFIHR13

The motor #1 dynoed at 415 hp/ 498 tq The Dart heads

Motor number 2 was worse by far, the AFR heads, didn't even break 400 HP, and had a bigger cam.

Both are tuned correctly.

These are actual cars by the way.
SO how does this happen? It defies the laws of common sense and marketing...

Dart makes a good product.

I wonder what the intakes were on each motor, as well as exhaust.

Too many variables...tune, mis-matched cam, exhaust, etc...

However, if you want to post a question that not dripping with sarcasm I would wonder how that happened...
