looks like the W-90 is still available from MoFoCo . my info says a stock Ty4 cam is lift 254 I 282 EX with a duration of255 I 296 EX. Looks close . WebCam has a # 73 with a lift of 426 and a duration of 262 (224 @ .050) that says "good overall power for engines with stock fuel injection and mechanical lifters" NOTE the lift at the cam would be .270 with a rocker of a 1.3 ratio Makes the lift .351. My recommendation is a WEB #86 or86a if you are using Carbs.
I have a WEBCAM # 86 for sale in classifieds now
