Guys - my original 289 engine in my 1966 Mustang has a pretty noticeable tapping, clicking sound. It is a 57 year old engine. Do I go with a rebuild/refurbishment of my 289? Or, buy a new 302 crate engine? It’s just a car for car shows, occasional Sunday drives. Summit Racing offers an ATK 302 crate engine, about $4,400. My mechanic hasn’t found an engine shop that has time to do a rebuild. 4 to 6 months out from even starting the work. But he estimates it may end up costing about the same as buying a crate. Tough decision. Any thoughts or experiences on this topic would be appreciated. Thx all.
