512 cad 230/236/110LSA

<< < (3/3)

Cliff Ruggles:
In recent years we've been going out to 112 and on to 114LSA camshafts in Pontiac 455 engines.  They have strokes from 4.21 to 4.25 and bore sizes up to 4.21".

We also tested a couple of cams on 110LSA's.  The 110LSA grinds did not make the field.  They tried to throw a lot of power at us early, idled worse, and narrowed up the power curve considerably.

The best results to date have been from the 114LSA grinds, in terms of smooth idle quality, strong "locomotive" type power over a broad rpm range, and strong top end charge......Cliff
