cam shafts 2
Posted: Wed Nov 19, 2008 11:17 pm
i was wondering whcih is the best camshaft for my engine now it has changed inside ..
it used to be a 110 v8 3.5 with 8.13 compression on carbs
it's now a 3.5 but with 10.5 compression on EFI & LPG
now as far i can gather the camshaft is the same as the high compression P6 one apart from a higher lift .. 9.9mm as opposed to 9.4mm of the 110 engine
but everything else is the same ..
110 v8 =
30* BTDC IN open
75* ABDC IN closed
68* BBDC EX open
37* ATDC EX closed
duration 280*
IN peak 112* ADTC
EX peak 105.5* BTDC
which are exactly the same as the P6 except from valve lift and of course the P6 has smaller valves
i have a P6 cam sitting here is it worth changing ?
or is there a better one , and is there any markings on the cams to tell which is which ..the one i have here has what looks like 5C X & 5D CWG
