Doing a partial rebuild of a 1200, down to the short block.  Engine has "stale-air" heating.  My question is can I install a later model 'tuned' exhaust readily available for 1600 based engines on the engine?

i dont think so cause the 1500 and 1600 are just about the same until you change the bore size ...... then you have f.i. which they only make 1 exhaust for but you might have to go with the handy tape measure and find yourself a 1600 long block and do some research??????
