where does this horsepower come from... and isnt the gear ratio different too

I know the heads are different. I think thats the main difference engine wise. I'm not aware of gear change.

35 horse from the heads, that doesnt seem right

Razor19

Different intake, cams, and heads.

When you look at the ports, it is very right. Look up a pictorial for a PI head swap and look how puny the 98 ports are compared to the 99+

i was wondering how much it would be to do this swap and how much would it benefit me, and if so where would i get them-off a wrecked 99 and do you have an idea of how hard it is to do this, labor wise. is it worth the money???
