Get a 181/208 or whatever it is or a 188/220 cam from Hamilton or a similar company. 90% of actually useful cams are the same price. If you want a direct drop in the 181/208 or 210 it might be is a direct drop in to a stock truck. If you go any smaller you will end up like the tons of other people you see in forums who keep upgrading cams. Best to do it once. If you want all out performance the 188 is apparently the way to go. That what I have sitting at home waiting to be put in. Hoping it will spool a s464 quite quickly

i hate that i have been MIA for a few months and on my second post have to argue. LOL i absolutly do not agree with the above post. a camshaft is like any other modification to an engine. it works best with parts that complement it. the bigger you go with anything the worse its gonna act on the street. choose a hp goal then a turbo and then everything else that complements those two items. i make just over 550hp on a 62mm turbo a colt big stick cam, 5x14's with 20* timing and am still able to use the truck as a truck. im nearly on the ragged edge making that kind of hp on a s362 but it allows me to use the truck. a bigger turbo would make more power but suck more on the street. exact same thing with a camshaft. you go too big for your hp goal and you will dramatically loose drive pressure and overall drivability to achieve a few more ponies way way up top where you probably dont want them. a big cam typically means more overlap. no street driven engine gas or diesel with a turbo like lots of overlap. most people dont need a cam or only really need a mild cam. people tend to go nuts with the size of things turbo, injectors, camshaft, ect ect when thats not how you build a good running anything. spec your build out and purchase accordingly. i have a 181, a 188/220 would spool my 62mm charger roughly 200 rpms slower but increase power up into the 4k+ range instead of having the curve lower in the 3k's

Not really into arguing and considering I have no real
Cam experience yet but how could a cam designed to spool a turbo better reduce low end grunt when that's what it's designed for. Every power stroke is more effective thus giving more low boost power because less boost is needed to create same power as well as pushing more air so getting to desired boost is faster. I agree with matching parts but a 181 is sized for like a 60 mm which is a very small common reasonable upgrade. The 188 is more suited for a 62 and up. Any lower seems like a waste of time and money for a minor boost in efficiency when you could just get a 181 for a mild truck and a 188 if you have bigger plans.

No that's not what I'm after at all and was kinda what I thought it was good for but everywhere that sells them says they r good for a tow cam so that would make them decent on the bottom end to me, I wish someone would chime in with personal experience.
