I asked some questions about this cam in Eddie 89 T/A's post a few days ago, and no one has had anything to say in response. I was wondering if this cam is enough of an improvement over a stock cam to justify the cost of it. I'm rebuilding an L98 right now,and my goal for now is to make it a little hotter than stock without having to change the chip. I figure I can always add 1.6 rockers in the future if I decide to upgrade my chip. Does anyone have any good or bad comments about using this cam? If I remember right, the specs are 214/220 duration@.050;452/465 gross lift w/1.5 rockers, and 112 degree centerline. Let me know what you guys think.

The 2032 is a very nice piece. I wanted a cam that would work normally aspirated as well as under boost, AND emissions legal. I use 1.6 rockers and very pleased with the results.

Thats the cam you want. A lot of guys go too big with the duration and valve lift. The specs of that crane cam will work great.
You may lose a little low end with the 112* lobe separation. Check out Comp Cams 08-304-8.
It's a pretty mild cam too and has the lobe sep of 114*. Car will idle better and still retain all of it's vacuum.

Oh yea if you plan to use forced induction, your lobe sep HAS to be 114* or higher. I've seen a lot of LT1/LS1 guys burn out their engines in under a year from using a supercharger or nitrous with their aftermarket cams at (112*).

There's a little bit more to it than just LSA. The 2032 is the perfect cam to use as an example for a cam with <114 LSA, but is perfect for a blown application. Yes, it is true that is has a 112 LSA, calculated by adding the maximum lift of the intake @ ATDC (107 deg) and maximum lift of the exhaust at BTDC (117 deg) and dividing by 2>>> (107 + 117)/2 = 112.

To calculate overlap, which must be minimized in a blown application, look at when the exhaust valve closes (-7 deg BTDC) and when the intake valve opens (0 deg BTDC)-- seven degrees of "non-overlap" period. Therefore, this cam has no overlap. In fact, if this cam were ground on a 114 LSA, the exhaust valve would close at -5 deg BTDC -- still five degrees apart from any overlap. Therefore, this cam is perfect for a blown application.

In summary, NEVER look at only LSA. Always get the valve timing specs.

If there is any doubt to what I state, call Crane cams (904.258.6174) and ask for yourself. My information was received directly from Crane.

No worries Willie, I trust what you say on the lobe separation. Makes perfect sense to me. You definitely don't want any overlap when boosting an engine. My main concern about this cam though was how big of an improvement it is over a stock one, and whether or not it would give the stock prom fits. The other cam I've been considering is the ZZ3 cam, or maybe the comp cams 08-304-8 that Formula mentioned. One thing is for sure, the camshaft is always the most perplexing thing for me to try and decide on when I'm rebuilding an engine! Especially considering the cost of the roller cams. Does anyone have any input on these other two cams versus the 2032? By the way, just to remind everyone, it's going in a L98 350 with TPI. I really appreciate everyone's help and suggestions, I think I'm starting to get my decision a little more narrowed down! Lol.

2032 results:

I just built up a 305 with a stock TPI intake, ported stock heads (9.8:1 CR), a 2032 cam, and 1.5:1 full roller rockers & dropped it into an '84 Berlinetta. The motor drives a 700R4 with 3.42:1 gears & GM posi behind it - it runs low 14's @ 3100 ft (high 13's corrected).

i also have the 2032 cam in my 305, i havent really played with it but it seems pretty awesome, althoug i've added S/R torquer heads at the same time, the cam says to use 3.73's or lower, i have 3.23's but going to 3.73's.

pat, the reason I recommended the 08-304-8 is because a guy i know (87 305 TPI 5speed all bolt ons) had trouble breaking 13s. He ran a best of 14.4 with every bolt on imaginable. WHen he got the comp cam he ran a 13.9@99mph

You might be able to get away with its big brother the 08-305-8.
