And all the economy SBC cams which I can find specs for, have reduced lift and duration. So 'undervavleing' seems to be the way to go for FE.
plym49 - another trip back to j-body.org, for spec's on my rockers, shows that not only does my 2.2L have a SBC profile cam, it uses the SBC rockers too! Sweet. If your experiment works out, perhaps you'll sell me four of your unused rockers 
oldschool - any clacking at low rpm with your anti pump up lifters? |
OK. If I do this I will let you know. I think that a set of 1.3 break-in rockers is about US $100, and I believe that they are only sold in sets of 16.
