i was asking about this in another post, but i started my own hoping to get more attention.
here's what i have: 91 GTP 5-speed with 96 block, heads, cam towers, and 91 uim and lim. i also have a set of 92 cam towers. i will in the near future be putting 96-97 uim and lim on the car.
here's what i know or think is true: 94-97 cam cogs are easier to change the timing on, 91-95 cams are supposed to be better than 96-97 cams (also have heard of possibly using exhaust cams on both banks), exhaust on 96-97 cams is 4* retarded, 96-97 cogs have more teeth, you want different timing for a manual vs. an automatic
so, my questions are, first off, if what i said is true. my next question is what timing do you guys personally recommend for essentially a 96 5-speed and should i use the 92 cams in the 96 carriers or a something different.
thanks in advance for any input. it would be nice for us to compile all the data and facts we have on this subject so people like me dont have to ask these questions all the time.
edit: i found the spec's on alldata for 92 vs. 97 cams. the lift inches, journal dia, bore id, and journal clearance are the same. the only difference is on the 97 engine, intake is at 108* crank atdc/exhaust is at 115* btdc and the 92 engine intake is at 112* atdc/exhaust is at 111* btdc. therefore, the cams are already +2/-2 cam (if im figuring that out right). i also found that 91 journal diameters were different than 92/97 (2.165-2.166 for 91) as well as camshaft bearing clearance from 91-92 at least (.0015-.0035 for 91). this also tells me (i think) that there is no benefit to using the older cams (unless its duration since i dont have those spec's) as i was led to believe.
