233/236 cam on 109 LSA for my LT1
first of all....
here's the specs:
233/236 @ .050
533 Intake, 569 w/ 1.6 RR
520 Exhaust, 555 w/ 1.6 RR
109 LSA
3* Advance
this is a custom grind cam from comp, i was told it was used with a stock bottom end and stock heads LT1 and full bolt ons to turn a 12.0 N/A with a turbo 350 in an Fbody. they said it was also a nitrous car but didnt get any times on the juice. im planning on putting it in my 97 T/A with a tune from Ion. i have LTs, full exhaust and most bolt ons along with a 125 wet shot that i sometimes spray, but not often. with about 98k miles on what i beleive is a well running and well taken care of motor. 3.42 gears with a 6 speed. i got it for very cheap and the local machine shop said it was in excellent shape and an emory cloth will bring it back to new for reinstall.
now my questions....
-obviously the cam will sound mean, however with those exact specs, am i looking at any real bad driveability problems?
-will 6500 RPM be enough to spin this thing to? like i said stock bottom end, so i dont wanna run it very high. im sure this thing would like upwards 7k RPM shift points but what will i be able to get away with, with my 6 speed and stock motor?
-anything else im overlooking with this cam? im considering it similar to a cc306 or a gm847, but what will be main differences with this cam?

its kinda big, but not too bad, my custom grind from AI is 224/234 on a 110, i wanted it to beat, and driveability is awesome no problems at all, i spin it to 6500 and its great. On yours you should be ok, especially with a 6 speed, will probably take more the 6500 but it wont be too far off so it wouldnt hurt shifting there, but i could be totally off, best way is to get it dyno'd and see where the powers at

i dont spray that often, and im aware ill prolly be wasting a lot of nitrous with that narrow of an LSA.
i was thinking of setting the rev limiter around 6,600 but getting a shift light set for around 6,300 so realisticially ill be shifting around 6,400 with a bit of room for error.
i plan on getting a tune from Ion at madz28 tuning. i think the duration is a nice setup and the lift should be good with the Crane 10308 spring kit, i already talked to Lloyd Elliot about that, im mainly concerned with the LSA like you guys are mentioning. i know it will thump a little more at idle and have that choppiness which i like, and i know it prolly wont drive close to stock (surging, bucking and bad gas mileage) but im fine with that. my main concern is its not gonna be TOO much for a bolt on car. BTW i drive it daily, however im almost outa school and i work down the street and drive the car about 10 miles a week, then for fun on the weekends.
like i said, wondering mostly about that LSA with these specs. other oppinions? im gonna be using GMPP 1.6 SA roller rockers, stock lifters and pushrods and the Crane 10308 spring kit. not the best setup to run with the cam, but im on a budget and trying to put together what i think will work well for my usage. 6,400 RPM will be seen maybe once a month. i really baby the car and wind it up to around 4k once a week maybe and go to the drag strip about 2 times a summer or so.

i have the cam and it is in excellent shape. im thinking this should be right around what im looking for as long as the LSA isnt too low and ill be fine with shifting around 6,300 or so maybe a bit higher.
i appreciate all thoughts, comments and oppinions but ive already made up my mind that this cam is going in or it's not, nothing else will be put in it's place as of now. so im just looking for some info about how this cam SHOULD act with my car and the specs it has. again, im not looking for thoughts about other cams or anything, i appreciate all comments but please help me figure out how the cam with the specs i listed will be in my car. thanks to all.

109 lsa is fine for nitrous as long as you dont go for huge hp shots. Seems like a great cam for stock heads, but I'm sure you can go bigger on the exhaust lift. Duration seems on the high side for drivability with stock heads and you'll have to spin a bit past where I would deem safe on stock Lt1(~6300) to reach its peak power, but seems like a great cam. Many spin to 6500 or so regularly without problems anyway, so you may be fine.
I do not know why people sacrifice NA power with "nitrous grind" cams then only run 150 shots.

im thinking it wont be the perfect cam for my setup but it will leave options open for me to do some headwork and gain a good amount or use the cam in a buildup i might do in a few years. and i think with a decent test and tune by Ion, he can get the car to run pretty well with these specs. ill have to talk to him more. any other thoughts are still great.
