I trust your guy's opinions as much if not more than the other forums so I'll ask here.
Friend called me he's building a 15.5:1 600" BBF A-460 heads etc etc ...7,400 7,600 rpm no nitrous just the peddle. He's looking for C-16 or F&L with the F&L stuff he can save something like $200.00 per 55 gal drum. But I don't know if he needs C-16 maybe he can use C-14 or C-14+ since he's not going to run Nos. Any suggestions.........
