I just replaced the engine in my truck (200 miles on the new stock engine), and with it I put it a new Elgin performance cam. Anyone have Desktop Dyno?? Here are the specs: Cam Lift INT=.280 EXH=.295 Valve Lift INT=.420 EXH=.443 Lobe Centers INT=107 EXH=117 SAE Duration INT=271 EXH=280 .050 Duration INT=204 EXH=214 SAE Timing BTC=27 ABC=71 BBC=76 ATC=32 .050 Timing BTC=-5 ABC=29 BBC=44 ATC=-10 I put the cam in but don't notice any real increase in power except for a loped idle. What's up with that??? This cam is VERY similar to the one installed in a certain 270hp replacement motor for the truck based on a GM Goodwrench stock replacement engine for my TBI.
