i found a 72 240Z today for sale in my town. the body and interior are in decent shape as is the engine. the PO swapped out the 2.4 for a 280Z engine (my guess is the L28). its the one with both intake and exhaust in the left side. this engine has been cammed, has a header/exhaust, and is running a 4bbl holley vac secondary on a clifford manifold, may also have had suspension work done as it sits lower than stock. the engine has a very lopey idle but has ferocious throttle response (revs VERY fast). and its quite loud. the asking price on this car is $3995 USD. is it worth the asking price or is it overpriced? also should i just pass this one up due to the mods
