It's not something that I plan to do right now, so no need to spend too much time on it... But if I were to consider purchasing 600 naturally aspirated HP, I see 2 offers on the web. PIM's Hammer and Summit's 521CUI 580. http://www.summitracing.com/parts/FMS-M-6007-521FT/
Which would be best? PIM's is supposed to be made for the Pantera? Which is the easiest to fit in the Pantera?
Has anybody bought any of these 2 engines and installed? And lived with it for a while?
