I spoke to a sales associate at Advance Auto and explaining to him that the engine I have inside my car is actual say 3400 SFI on top mount; clearly GP does not come with 3400 engines so the prior owner before me had replace the original engine with this one currently. Now, I am unsure what engine it is which leaves me unclear what radiator to purchase. I do know the 3400 engine is 3.4L, V6 but I'm GUESSING its a Pontiac Grand AM GT engine or Monte Carlo, I do not know? I uploaded a photo of engine so I get some kind of direction....please help!!
