contradicting engine specs on spark arrestors
Both of these are 1988 mercruiser racing 320 EFI 5.7 liter bravos
Both motors look identical. both flame arestors the same , decals on them the same except the stb one says timing 8* btdc and the port 12* (they may not be on the correct side)
the manual oem mercruiser says 12*
I also have th eoriginal paperwork from Formula test tank inspection on 8/31/87 and both motors had timing at 12* btdc
serial no on motors
stbd-b858846 port-b858853
is this a typo or correct? if correct why?
Also I just happened to look into the stb valve cover where you pour oil into and there are roller tip rockers. didnt check the port side yet
thanks
