I met and talked to that guy at a small car show down there at the restaurant by the 13 toll booth building. Nice gent. Had lots of nice things to say about my then nice Formula. Lol
I am sure someone put the injectors and intake on an 86 jeep comanche. Used the same block but was only carb'd so would sound like a good fit. does that count?
I've seen a couple 308s on the Internet previously that had a 2.8 swapped in, but I don't know if it was the Fiero L44 or even a 2.8, as they were carbed, and valve covers were painted differently.
And yeah, MG and Triumph have often had the 60 degree V6 swapped in.
There's certainly no shortage of the GM 60 degree V6 engines in the wild, but I think most of the ones swapped into other cars are not the one that came in the Fiero.
Such is the problem with the 2.8 /3.4 etc is the fact that GM made it as small a package as they could so they could drop into anything they came up with; IE the useless/power killing intake manifolds and headers.
