Need Cam Recommendation Putting together a N/A Lq4 with a L92 head. The heads will not be ported or milled. I may have the exhaust cleaned up a little. The motor is going to have a 750 or an 850 carb. It's going in my 1996 S10, the car has a 350 trans with a 3400 to 3800 stall, with 4.10 gear, 28 in tall tire. Will take to the track and drive it on the street. The header I will run is a 1 3/4 long tube. I'm looking for a cam I don't have to fly cut the pistons. I would like to make as much hp a possible. I think a cam around the high 500's. The car will not see any boost or laughing gas. I'm open for suggestions
BTw I'm running my stock rockers with an aftermarket pushrod with a single or maybe double spring. From what I hear a single should do. Thanks

have pred z spec you a cam.....
my suggestion is 234/250 .598/.595 112+4
from what ive read those heads favor a little more exhaust duration (around 10-20 degrees)
what kinda power are you lookin to make?
if its gonna hit the street i'd do something like a 224/236 .609/.605 112+4

From what I seen power levels around 470. I'm not going to lie about it, I would like to get into the mid to low 500 range. Lets say 550 peak hp.. I've seen carcraft clam that they made 550 peak hp. with the same set up. Not to concerned with peak as i am with avg. hp.. I'll see what they recommend.
What does 112+4 mean.

i was under the impression they liked that much more exhaust duration......
but if not there is always something like a 224/238 .609/.605 112+4
but if its according to pred z a cam like 224/238 .609/.605 112+4 is 7* overlap and is very streetable with low 6300+ shifts

I have seen that on stock cubic inch motors these L92s don't need a humongous split to make power, that seems to more apply to bigger cube strokers. If you aren't going to mill the heads you can get away with a decent size cam but you will have pretty low compression for an all motor set up. I would recommend considering going with a little bit smaller of a cam and milling the heads to try and get some more compression in the motor. IMO the motor, especially being run N/A, wil benefit more from a bump in compression than a huge cam.

So far, you've made THREE suggestions in this thread. None of which will work for the particular combination in the thread, but then again, WTF do I know. I'm only a low post count *restricted user*
