Adjustable cam pulleys will make certain accurate timing and cylinder force tuning. Forged substantial compression pistons are reasonably priced and so are a good update. Modifying to a late model head would require fabrication of a brand new consumption structure for RWD. The throttle body can be enlarged To optimize air ingestion.

Pistons, connecting rods, and to a lesser degree, crankshafts have all been up to date with lighter body weight design. The good news is always that it remained an iron block- the engines ended up still on solid foundation for large and really serious modifications.
Despite studies of dissimilarities all 20V engines as well as the afterwards product 16V engines use the identical aspect number to the crank.
