318 MAX fuel economy builds?
There's a whole fiero culture around different engines.
Basically any SBC bolt pattern block can fit.
Buick turbo v6 is another popular one.
I pass a late gt on my way to and from work, in a used car lot.
I've been tempted to stop in and ask about it.
Once before, I though I wanted one. Not really enough headroom for me, though. I'd need to do a T top conversion.....if I could find the parts.
I came close to buying a 2.8 5 speed se from a guy that literally had a warehouse full of them including a driving northstar conversion and a WIP 3.8 turbo.
I've seen a few Ferrari 3x8 body conversions that you can't tell ain't "real".
Pontiac actually even made one from the factory....and got sued.
