Hi Anthony that's a great looking GTR.

So your 2850S definitely had an XH cam in it? I've seen that in the LC parts catalogue and wondered why it'd be there, seems like an awful big cam for a little engine with significantly less compression (compared to 186 and 202 XU1) and single 2BBL carb. Are you sure it wasn't hidden in the parts catalogue like some other HDT stuff was so the cam could be used in Series Production GTR? This is how Harry hid the 3927186 heads for GTS350 so it all appeared above board. Just seems an awful big cam, for only an extra 5hp which you'd think you'd get anyway from the extra 12ci and 0.2:1 compression between a 2600S and a 2850S.

Byron, according to the 173s engine specs sent to the dealers in August 1971 the XH camshaft would not have been the factory fitted cam. The listed timing specs suggests a camshaft not much wilder than that fitted to the 161s engine.

 

You may be right. Listing the XH cam as fitting the 173s in the parts catalogue would allow the use of the cam in the 173s in competition without GMH having to submit an amendment to the LC GTR C.O.D for it.
