need more info, the lift means almost nothing, you will need to give us the duration @ .050, the rest of the number would help too, but most important is the advanced duration

how can you make a suggestion without knowing what the advanced duration is, for all you know this could be a hyd roller with a advanced duration of 214-222 and then a 3000 stall would not work it would be too high, the only way to give an educated answer is to know the advertised duration

let me guess this is a summit brand cam

power band for the cam is 3500-7000, you wont want to run less than a 3800 stall i would opt for a 4000 stall, what are you putting this into, cause most people who pick this agressive of a cam wouldn't buy it under a hyd f/t grind and wouldn't get it with a 114LSA unless it was for a BBC

oh and to mr. brown, i told you that you can't pick a stall without knowing the advanced duration. so thank you sir

i just have to say it mr. brown, you say you're a chevy boy but yet you your thumb nail pick is of a mopar motor

wow guy, i know he has a SBC not a BBc, i said that not many people would buy a cam that agressive with a 114LSA unless it was going into a BBC. dont misunderstand me.

an i have looked up the cam, it has an operating range of 3500-7000, you want you stall speed to be aprox 500 rpm above the begining of your cams power band, i know what i'm talking about here. ask around.

i just dont like it when people make blind recomendations, it never helps the OP with their issue. if he used a 3000 stall then it would be soggy off the line. trust me, i run a 385ci motor with a solid f/t cam that's 240/250 @ 050 the cams power band is 3000-6200, since it's a 385 and most all cam manufactures power band ratings are based on a 350 i have to take into acount it the extra 35ci which will make the cams power band more like 2700-6000 so i use a 3500 stall (same thing goes for the stalls as goes for the cam, more ci eats band)

what are you doing with this truck, with this cam you will need to run a decent compression around 10.5+:1, and since it is going into a 4500-5000lbs truck you will need a very low set of gears, i would say no less than a 4.10 but i would recomend a 4.56, with this cam your power will all be made up high and you wont have much down low tq, your peak tq will be around 5500 and for a track truck that is fine but for the street you want it more into the 4000-4500rpm range. as long as you have a decent set of heads to go with it, say 200+cc then you should make pretty good peak hp/tq numbers but your band is much more likely to short and that is why you would want the short gears. you will loose some power from the 114LSA as it will bleed off cylinder pressure but if you're trying to run it on the street this will help you just a bit, but if you dont get the rest of the set up right then it will be a dog on the street

you could call comp cams, they may help you but they will tell you exaclty what i have just told you. you will get far more accurate information on this site and it's knowlegeable people than you will get anywhere else.

you will need a 3800-4000 stall, likely 4.56 gears, and a set of 200-210cc heads capable of flowing 250+cfm @ .500", 10.5:1 compression, and atleast a 750 double pumper carb to get that thing to really do what you want. if that is really what you wanted in the first place

Not a good cam for a truck motor unless you plan on a supercharger to go with it.
Do not use less than a 3500 stall converter. A 3000 stall is not enough converter for this cam it needs a very loose high stall converter to idle correctly 3800-4500 stall best. 9" 9.5" or 10" diameter.

4.56-5.13 gears, If tall tires, go even steeper gears, locked out distributor advance allows full timing at idle.. Low manifold vacuum at idle. low vacuum rated 3.5" carb power valve.

Needs high compression unless supercharged.

Why would you order a camshaft and then start asking questions?

355 chevy

well when i got this engine they didnt know the cam specs, i installed a howard 488/488 lift cam in a 355 a couple months back and it sounded awsome. i have all the specs for that cam somewhere ill find them, basically what im wanting is something that sounds great, not a race truck but has a good tone. i may not even use this cam becouse i know it will be hard on it being in a truck, what size cam would you recomend for a 1986 chevy shortwide with a 355 chevy engine in it

You must know the static compression ratio of the motor before you can intelligently choose a camshaft. That's the first thing the tech at any cam grinder will ask you when you call them for a recommendation.

I would like very much to know what it is that makes a fellow choose a camshaft out of mid air without knowing anything about his motor.
