Like any aftermarket engine block, the TA alum block has to be prepared properly for reliable performance. A shop that has experience building alum race blocks will be familiar with the proper machine methods and tolerances.
For example, the cylinder liners are not cast iron, but are made of harder material which requires a special hone and method.
The normal bore size is 3.90, but a 3.80 liner is available. Certainly the larger bore is very beneficial to performance.
If the proper size piston is selected, a stroker kit can be used.
Since the basic design is from a stage II block, 14 bolt heads stock style heads can be used.
