I just bought a '87 T with a 20-year old performance rebuild but from what I can gather from the previous owner and other historical documentation, it has fairly few miles and likely no abuse. I have another complete built motor on a stand, but this motor currently in the car seems pretty solid so I figured I'll run it awhile with a milder setup, then when I go much bigger on the combo I'll go ahead and put my all forged, girdled, GN1-headed motor in.
This older motor in the car was sold to me with a "Kenne Bell Cam and ported heads" I can not find any of my old KB catalogs, and the cam sounds pretty small but I can certainly hear the valvetrain. One note with car referenced the cam as a "260" cam and I know most of the 212/212 tappet cams had 260 deg adv duration - so that is a pretty solid guess on which it is.
But does anyone have a rundown on their old offerings so I can try and figure out for sure which springs to drop in as replacements?
I'd figure 980's might be a safe bet, but it would be nice to know what they were actually putting with their stuff. Would a 981 be too much on one of these older tappet cam/lifter setups?
Thanks in advance,
John
