as far as the cam goes, i had always thought the wider lsa cams had more cylinder pressure because of the lack of overlap bleeding off cylinder pressure. i went with this cam to be more nitrous friendly. i was talking to Jim Butler and we came up with this grind and when i ran it on Desktop dyno this cam actually out performed the 290b-6 by about 10hp peak and anywhere from 5-15 through out the curve. but i do put too much trust in the program. i need to study hard facts better i guess. i swapped distributors to see if there may have been advance issues but either one did the same. i will try locking out the advance. i just have never seen an engine prefer 50 degrees like this.
