Older pushrod engines especially 80's ad older that's fine. Cause the clearances were wide and with wear and tear they're even wider.. Thicker oil won't hurt or additive..

But modulars, have very very tight clearances and once again,


NO CAM BEARINGS.. So if the oil is to thick, won't get in between head and cam to lubricate em and will burn cam up and have head noise..
