looking at it right now. Quote from article: (as to why they chose PI heads)
"Some builders swear the non-PI head is every bit as good after porting, but the compression bump was what we were after."
For those of you wondering why they would use stock PI heads over ported non-PI heads, it wasn't for the price. They only used stock PI heads (with other mods) for "stage1 and 2" making 313.6 HP and 315.1 LB-FT. Stage 3 only consisted of swapping to PORTED PI HEADS! with 46mm SI valves bumping power up to 346.1 HP and 341.2 LB-FT. I don't think price was an issue either cuz those ported PI heads cost them $1,199.99!

The other reason they used the PI heads was because of Edelbrock. The carb intake they used was designed for the PI heads.

The stage 1 set up sounds very interesting. Can you bolt up an old AOD transmission to that set up and avoid a computer all to togather or would you be stuck using a manual?
