I found a LX code 425 locally with dual quads and a s.p. th400 behind it. the engine has 40 thousand miles on it and seems to be all that the seller claims. correct dual quad distributor correct carbs. no aircleaner but otherwise complete. would this assy be worth the 1500 asking price? would my 401 4 speed flywheel be ok on this engine? would this engine be a noticable increase in power over my stock 401?
