is there anymore info on these motors? do they make aftermarket parts for these? seems like out of the 425 472 and the 500 block the 425 is the wekest? and no 1 makes parts for these performance wise, are these reliable motors? i might be picking up a 78/79 coupe deville that got a 425 in there,what should i look for? what should i replace??? any help

the 425 is the weakest power-wise, but it has the same block as the 500, so it is very durable and reliable.

MTS (http://www.500cid.com/Store%20Home.htm) makes performance parts for the 425/472/500 series of engines.
