[x NOODLES x]

A swift kick in the ass. :lol:

 

[meaty mac]

what kind of vehicle you got bud?
transmission?

 

[CHC speed]

2000 GT with the stock 5-speed tranny.

 

[meaty mac]

i have never heard of those cams- don't you mean 262ah or 270ah?

 

[CHC speed]

Sorry, I'm talking about the part number not the grind, the grind is between 270ah and 278ah.

Here is the link I'm going off of.

I have the 102700's with an accufab tb/ plenum,intake, bk shorties,3.73's, fidanza adj cam gears and put down 290 rwhp. The pistons did have to be fly cut.

 

[CHC speed]

What do you mean "fly cut"?

 

[99MustangGTman]

fly cut basically means the pistons have a groove in them in order to compensate for the amount of room it takes for the valve to travel down so that they dont smash against the piston, i dont see why you shouldnt make 280-300rwhp

 

[meaty mac]

is there a power adder in your future? that can make a difference.

 

[CHC speed]

long term is a stroker kit p&p heads than procharger

 

[meaty mac]

then you would want the bad boy (278ah)

Comp cams said that i would not need to fly cut.Why did that other guy. Did he change pistons?

 

[LuDamiKE81]

I dont know what pistons comp is using. On the stock pistons with those cams the valves hit. I think it was around .060 they cut off. There is a ring around the outside of the piston that sits up a bit more then the middle. That has to trimmed down. I would have pics but i threw all the stock crap away after the bearings spun.
