How reliable are snout extensions for the fuel pump?

Correct me if I'm wrong, but the 1985-'89 M-bodies were carbureted with mechanical fuel pumps. With the exception of the AHB (cop) engines, they also all had roller lifters. It would make sense that they'd just use the one LA cam blank, but then again I'm not a large corporation that pisses away money for no discernable reason.

mid to late 84 (so model year 85) was the roll out for the roller motors. i've seen 85 rollers, but mostly 87+ however, i don't know if that's just a function of my location. to my understanding trucks and vans got TBI in 88-ish the 318 for sure, i'm not 100% on the 360. but the cars didn't and stayed carb and the HD/Police/taxi E series motors stayed flat tappet till the end.

as an aside, i know that imperials (and maybe cordobas) got an early type of TBI in 81 (or so) and that was a whole *** kerfuffle of bad juju and a rush job that was basically a dumpster fire. apparently the "fix" was to tear it all off and put back on a carb. (lolz)

anyway, ma mopar being ma mopar it's one of those: ya never know till you open it!
