This is a very basic question that I am hesitant to ask... I have worked on this car for 5 years, learned a lot from this forum, even have my own tools , but I have no idea how to answer this when I am looking for parts.

I have seen options for an FI-2 or FI-5 engine.
At AutoZone, there are different parts (i.e. plugs) for OHV-overhead valves or non-OHV.

I asked LR, and the tech told me that all 2001's have OHV's.

How would I determine if I have an FI-2, FI-5? confirm I have OHV?

Thanks for any help you guys can offer.

 

just about ever engine made in the past 30 years has OHVs..no idea about the FI-2 and FI-5.

 

I have been wondering that too for the past while.

 

You are looking at an old pushrod Buick 215. Works like most other old V-8's, but it is aluminum.

The designations are for VIN codes and I am pretty sure it is secondary air or not.
