hi, heard a lot about the AFR 185, and 165, I have a stock eng,, is this cam and 185's a lil too much for the stock bottom end,,,, if not that sounds pretty good to me, those 185's are real expensive, ,,, any idea of h.p. with the stock (19) inj.,,,, or should I go ahead and up-grade to 24lb, and m.air meter? A guy on ebay had 1970 doosumthing 351 w heads w/chevy 196/160 valves and exh. ported (exh. HUMP),,,, all rebuilt, shipped for about 650, said he runs a mach. shop, they looked real good to me, but I dont know for sure, so i didnt get them, thanxs for the info
