i have a friend with a 5.5L 99 cobra. used a 5.1 crank and bored it like .60 over or something. a set of pistons cost him 1200 dollas

I think he is bull****ting you. If ya do a 60 over bore in a 4.6L block, it would probably glow if you dropped a light into the cyl.
Besides that cyl bore adds very little displacement. The largest kit i have seen with a stock block was a 5.1L.

nope its sleeved. ask code. i helped this guy put it together

David_K is talking about my motor. It is like a 5.3L or something. The bore on this motor is .154 over not .60 like David_K said... [sm=chairshot.gif]
the bore is 3.704 and the stroke is a 3.755... piston size is 3.695... rod length is 5.880. Put that all together and you will come up to a 324 cid. Here is the formula to come up with any cid:
Formula to Calculate the CID (Cubic Inch Displacement) of an engine:
R² × Pi × H × number of cylinders = CID (Cubic Inch Displacement)
In other words;
Radius of the bore squared × 3.14 × Stroke × number of cylinders = CID
For my engine with a 3.704" bore and a 3.755" stroke, the formula reads:
1.852² × 3.14 × 3.755" × 8 = 323.52772 CID = 324 CID
In other words;
1.852² (The radius of a 3.704" bore [1.852"] squared [multiplied by itself, or 1.852 × 1.852] × 3.14 (Pi = 3.14) × 3.755 (3.755" stroke) × 8 (The number of cylinders in this engine) = 323.52772 CID
This formula will work with any engine. For example, the Oldsmobile 350 V8, which has a bore of 4.057" and a stroke of 3.385" would be;
2.0285² × 3.14 × 3.385 x 8 = 349.88742333922 CID
A Ford 351 with a bore of 4" and a stroke of 3.5" would be;
2² × 3.14 × 3.5 × 8 = 351.68 CID
MAKE ANY SENSE?
