390 vs 408

You bet that 390 is rare,most people don't even bother dumping big money into 318's...mild 440 no problem for a 360 built right,never mind what a 416 could do to it..you see i actually RACE my car so i know EXACTELY what the 360 and 416 run,no speculations here..only timeslips to prove it..:-D:-D
