machene notches into 2ltr 8 valve pistons, fit them to the ABF block, keeps the squish zone so can get more spark on without problems.
i prefer the M90 of the jag, the charger lends itself to fitting quite well and bigger charger displacement means the cherger rpm can be droped reduceing noise and charge temps and makes it a bit more efficent.
STD abf manifold is best replaced with a custom log, shoule be abel to get one made for not to much money as there not that hard to make
