I think it would be great to put a list of high performance products for the cadillac 425 engine. There are many parts for the 472's and 500's but not as many for those years engine. List any parts that you've tried and work or that you know will work. Upgrading that engine is fairly hard to do withought extensive work. Anything helps.
What I know will work:
Those crappy chrome valve covers, cloyes timing chain, accel 45,000volt and 50,000volt coils, 14x3 air filter housing off of an 80's Fuel Injected Caddy(for a larger K&N then the stock element). Anyone know of headers that would work. Maybe off of a chevy or something?
