Wanting to take my turbo 01 cobra to the next level by removing the oem teksid sb and forged crank and adding low mileage 03 cobra rods and pistons.

ENGINE BALANCE and hone $ 150.00 (match pistons to best bore)

Ring filer

Important:
* On pistons near wrist pins on 1 side there is a boss. The boss points toward front of engine. On rods SVT and Manley logo point towards front of block also both bearing retaining tabs on rod are on the same side ( rod and cap ). Pistons have offset wrist pins. From the driver seat both wrist pins shift to the right of the engine. IE: From driver seat wrist pin center on passenger side pistons is closer to exhaust manifolds and wrist pin center on drivers side pistons is closer to intake manifold. M
* Top and second ring gap is cylinder bore (3.552 in ) x .006 or approx. .022 in
+ .002 more gap on second ring (personal preference)(.024 in )
* Piston to wall clearance from .0035-.0045 in for forged pistons (4032)
