Newbie to Pure Stock

I am going to contact Mike Baker tomorrow to find out the exact specs for IHRA. According to the NHRA specs, the 1987 Olds Cutlass Salon 307 had three different advertised hp ratings. 138 hp/ factored to 210 hp, 140 hp/ factored to 232 hp, and 180 hp factored to 232 hp. The shipping weight is 3227 lbs. Using the 138 hp/210 hp rated motor would put my combo as a natural H/PS. I can move one up or down accordingly. Do I have to use the ECM controlled carb, and distributor, or can I switch it to a OEM non computer application. Also the NHRA blueprint guide states that the stock lift specs on the cam is .474 int/exh. Is that valid in IHRA pure stock? I have checked the IHRA updates, and the is no info on the Olds 307.
