The biggest issue with the opti-spark is folks tend to wanna mess with them, Think on this, there are thousands of cop cars and taxis running that engine with little or no problem.. Great engine that makes lotsa power. Just put one in a 1964 Chevy truck, runs like a bat outa hell with a little head and cam work. Get the fresh air vented opti cover ,95 and up and the moisture goes away. I drill and tap the water pump weep hole for 1/8 inch pipe and run a barb and drain hose away from the front of the engine. Good parts are getting hard to find but there are some good books on Amazon about this power train that are worth having
