My pistons had to be notched for the 270ah's I have.
Mine too. I figured this out when I installed them on a stock motor and ended up with PTV. The I got a built motor with notched pistons.
Exact same thing! H/C first, then PVT, then new shortblock. lol

Was this because you advanced the timing? Because the cams are already at 4 degrees advanced!

No the non-pi have 11cc dished pistons and the PI have 17cc dished. So I suppose if it happened on the pi then it will def. happen on my non-pi! bummer I'm just gonna sell the damn thing. no mods are worth anything and the cars got no power. I duno why I bought a ford. I've always been a GM guy!

I have heard of people that actually took the time to degree the cams with the motor in the car get away with 270ah on pi swapped cars.

there is no difference in the short blocks of a npi and a pi block except the piston have a deeper dish but like someone said above that make no difference because the valve actualy hit the flat top surface of the piston.

Just get an entire PI engine from a junkyard and you will be much happyer. If you still want to spend the money on the cams at that point you can get a set of the 270s etc.

If your looking for n/a or bolton performance though, you definatly picked the wrong car.
