Which cams for an original engine ?

http://store.schnitzracing.com/web-cam- ... 00-gs1150/

70-112 ?

What else do I need ?
What must be changed/modified using Webcams ?

I had a G4 grind which was to much. G2 was once recommended to me. It says on the website you attached that you need stronger cam followers

have a look at what Web Cam are saying in their catalog..

the 70-112 looks like a nice set of hot street cams to me.. but harder springs are recommended.. and "hardwelded rockers", but these are really expensive IIRC.. so perhaps install new stock rockers (along with full synth oil and 750 oilpump gears) instead..

OEM rocker arms aren´t really cheap, too ...

"Must remove oil bump from rocker" ???

Oil bump ?

What about 70-102 ?
In my engine are 100hp cams .... with these it would even run better I think .. but are they better than used stock 124hp cams ?

70-282 ?

ow.. yes, quite costly.. collecting good ones from old heads is the cheap way to do it..

worn rockers can however be perfectly good candidates for getting "hard-welded"..

btw.. Web Cam recommends these rockers even for their mildest cams, so that's more to do with avoiding any possible damage claims than it being really necessary.. :roll:

Same goes (to a degree) for the harder springs..
but good oil and good oil supply is always necessary to avoid increased wear from hotter cams..

..
Oil bump ?

more pronounced on some rockers than others..

(GSX rocker on the right)

but evenso, I've never had to grind one down to avoid it getting hit by the cam lobe.. (only used hot street cams myself though)..
another precaution to avoid claims.. but DO check if indeed none of them are dragging on the lobes, just to be sure..

167, (cams are referred to by their "grind number" btw.. 70-102 is a "part number"), about stock lift.. don't know what the stock duration is, so couldn't say much about how these would compare.. but looks like a set of cams just over stock spec..

223 (70-282), fits in between the stockish 167 and the hot 168 you asked about earlier..

look at what Web Cam are saying the cams are intended for, and compare that to what engine you're building, and what you'll be using it for..
with tuning engines, parts should be selected to work together.. the parts should suit the "state of tune" you're looking for..
bolting super hot cams into an otherwise stock engine with stock carbs, exhaust, etc.. hardly increases the power, but will increase wear..

I have searched the web and made a list of all cams that would go in the stock efe engine, but I can´t upload a ".txt" file here :?:
