ARe these engines from japan? I never seen this b4 but was wondering if mabey u have?

I am quite sure ATK is a Japanese company, but they may have facilities here in the US to save on shipping costs to keep their prices as reasonable as they are.

I bought one of their crate engines back in 88 or 89 for my then street 280, and then raced the car in ITS with the engine in it. Never had a minutes problem with the engine in 9 races and through 3 drivers schools. I couldn't run with the 240's because of the weight of the 280, yet there was only one 280 that could beat me. Back then ITS was almost all Z cars so I had plenty of competition.

I still have the car, and even after sitting for over 5 years it still started with just a fresh battery, and will usually start on the second time I hit the key. This should give you an indication that the ATK engines are well worth the money. If I were in the market for a remanufactured engine for a Z, ATK would be the only one I would buy.

I have done two ATK replacements in two Zcars.One was 15years ago. One 10 years.Both still perform excellent,never a moments problem.They're the only way to go. Daniel
