what mods do you have and what do you plan on doing to the motor in the future? keeping the head stock or are you going to port it out and run larger valves? what carb do you plan on running? street truck? trail finder? daily driver?
There are lots of useage specifics that play a role. Gear ratio, tire size, 2 or 4wd, ect. Also, the carb, ignition and exhaust style you run plays a role. If you're keeping things fairly stock, a mild RV cam should work with stock valves. For a more modded street motor with header, weber, ect; I woul say something about .450 lift would be best. These heads run into valve spring issues about 470 lift, and overall lift issues at about .500" lift. The duration and other cam specs play a role too, but not as much as the lift itself. That sets the whole cam profile. Brands like LCE, engnbldr, crower, comp cams, delta cams, Schneider racing and others have 20/22r cams.
I have a cam for sale coincedentally... lol its a web cam but pretty aggressive. Requires upgraded valve train. thats why I havent used it in mine.
i want stock heads for now than i will stroke it or supercharge it with a supercharger somebody was selling on craigslist but i dont know
how do you drive the truck? Do you throw it around a lot in high rpm, cruize around in low rpm a lot, want something all-around, race, tow, haul, etc?
If your intended on running a blower . You'll want a cam with a large 112 and higher lobe separation as they are better suited to making the most of a forced air engine as they begin to make power sooner ..tighter lobes aka overlap . Will not make the best use of your boost and are better suited for all motor set ups and or motors utilizing high compression and well flowing head as they are generally upper rpm cams and are doggie at lower rpms do to cylinder pressure bleed off . Like my motor a turd below 3500rpm If you do not plan on upgrading valve springs There are some small street cams from LC and engnbldr that are suited for stock rpm range and compression . < large factor when considering cams
The cam is the heart of any engine, I run the Pro Street version that comes in LC's Pro Street stage 1 engine. Comes alive @ 3,200 , pulls hard from there on up!!
Web Cam Inc. - Performance and Racing Camshafts I believe its the grind #91 Tried to direct link, search auto> toyota>22r-re
when they mean to regrind them do you send out your stock cam? street cruise low rpm but i wannt it to pickup fast from a dig
Without breaking the bank any of the engnbldr cams usually around 80 bucks .. If you want the low grunt the torquer cam . Has the low rpm range but suffers up top The engnblder I think 270 cam s the mid range high range cam with a slight suffer to off idle performance as I've herd this seems to be the preferred one for 2wd These cams are regrinds of the oem cam so there really just moving the power around in the rpm operating range .thats why there not as expensive ..but do give a little bump to the 22r
Valve lift: .475/.475 Duration: 265*/265* Duration @ 0.050" :236*/236* Is it too big that it would need valve reliefs cut into the pistons?
No stock un decked head 265 at fifty not to bad . Defiantly wanna run springs .. A bump in compression would help .
I assumed the same but can never be too sure. Was waiting for you to chime in,lol! I'd be running it on a worked head. And of course, aftermarket valve train
Yea anything over 280 ish on duration a stock motor won't see any results and will end up being slower . Compression x degreeing the cam are large factors for making any motor benefit from high lift or long or short durations tha aftermarket cams give ... You can stick a big cam in anything and get that cool lumpy idle . But if the motor isn't built for it .. (Your gonna have a bad time )
Built head, stock block unfortunately for now. Ill keep that info in mind when searching for more cams. That's scrub!
