now thats funny..cruel, but humorous..cliffs car runs well..he did his homework to optimize "his" combo..it aint no race car, but it works better than most pontiac bracket guys..

i like the 106-108 lobe centers..always worked for me, and we built our cars around that "violent" midrange..if i recall, my "stock eliminator grind" was like 244-230 at 050, and 106 lsa..??100 degree intake center??..however it came out, (17 years back), the same cammy held the l/stock record with a 4 speed..

the mild pontiac port responds well to tight lobes in a shorter stroke..i like them in 4.21 cranks too, but i have seen 113-115 lobes produce super smooth results as cliff has found..lower peak, but long pulls..for the street, his approch is more correct imo..and remember he runs a q-jet..the carb helps tell ya what cam to run

as for short cams, with tight lobes, i'd try it..but run 3.08- 3.31 gears, and a good 2 barrel, with adequate exhaust..
