You can see here where Harold at UltraDyne used narrow lobe separations on Pontiac:

Both Chris Mays at Comp and John Partridge at Bullet have recommended, and I've used cams with a 108 LS on a 4.210" stroke.

Lee used a 108 LS with his UltraDyne 231 degree hyd flat tappet cam, then changed to a solid flat tappet with 247 degrees and the same 108 LS. His car picked up. And if memory serves me right street driveability wasn't much different.

Jim Butler used to tout the UltraDyne 243/251 solid flat tappet cam with a 110 LS as potential for 1.2 BHP/CID at 9.5 compression. 455 = 540 hp.
