id reccomend one of these :

comp XE264HR
Grind: 264
Lift: .487''/.495''
RPM Range: 1200-5200

comp XE270HR
Grind: 270
Lift: .495''/.502''
RPM Range: 1600-5400

with the amount the AFR 190cc heads flow.... you should take advantage of the airflow with larger cam than the lt4 hot.... those cams would be good.... the 264 is probably what u want... for a little more power and lift you could slap on a set of 1.6 rockers.

There's nothing special about the L98 shortblock. Get yourself any 350 core and build it the way you want to build it. I'd recommend getting a 85-up block so that you can use the same flywheel though.
