I raced a GT6 in the 70s with a "Kastner motor" built to his specs and with
his S5 cam and valve gear . With tripple 42mm Webers (worked better than the
45s) 12:1 cpmpression on avgas it had a very reliable 200hp confirmed on a
reliable dyno . The only problem i had was breaking gear boxes and rear
axles which was fixed by installing a TR6 box and axles. Conclusion is the
2litre motor is capable of producing a reliable 200hp if built properly
