I agree.98GTSTANG said:I was looking at doing this without the head swap, but if the engine is out of the car why not put the newer heads in?

blackfang said:The PI cam and intake swap also provides decent power gains absent the draw backs associated with the PI head and intake swap. Swapping PI cams and a PI intake on nPI Stangs results in a 30 – 35 RWHP gain. The cams alone result in a 13 – 16 RWHP gain and the intake results in a 15 -18 RWHP gain. The extra 10-15 on the PI head is the bump in compression with an added cost for the heads.
The benefits of this swap are lower costs, less labor, and the fact that you maintain stock compression ratios.
What he was referring to was just the PI intake and Cams swap...stating that the heads don't add much power but the bump in compression is what is making up the hp difference. So not using PI heads will maintain stock compression and cost less.BOOSTED98GT said:blackfang said:The PI cam and intake swap also provides decent power gains absent the draw backs associated with the PI head and intake swap.

Just wanted to note a conflict of information. The PI swap does indeed increase compression by nearly a point to approximately 10.3:1.
