Wrench with a 350. I was just told in the HIPO forum that why wuld I need or want that much HP that not even 600 HP crank engines will lay that much down. I know little about older cars and HP performance, but I know it is not uncommon to see 450RWHP on new model chargers as my own, so i figured my Apache could accomplish the same just wanted ideas on how best way to get there. If this figure is unreasonable what is a safe and logical RWHP I could establish with a 350 engine and a 700r4.
