The 3800 designation started in 88 when they redesigned the 3.8. They are both the same displacement, 3.8 Liters, and share many parts. The 3800 has a balance shaft, redesigned block, different heads, and many other changes. In 88 they sold both engines, but the T-type only got the 3800. The 3800 is also know as a VIN C engine, as the eight VIN number is a C. The 86-88"3.8" is known as the Vin 3.

I noticed my 1988 3800 is rollerized and has DIS ignition. Is there any difference there? Or do they both have that.

I also noticed that the intake plenum and SFI on my car actually say "3800" on the top, while the older models have lines cast into them that match the valvecovers, and look alot like the systems on the old corvettes. Other than that the system in general looks to be the same. I want to swap over to the older system for esthetics but only if there's no change in performance. Any info on that?

intake and valve covers will not swap. Both had DIS, SPFI, and roller lifters.

88+ years I understand, the ECMs are more faster Acting, the camshaft is more centerline? and the Pistons are lighter, correct me guys if Iam wrong. :wtt:

i know this is old but i am new and i found this on wikipedia
[edit] 3.8 FWD
In mid-1984, the engine was modified for transverse-mounting in smaller, FWD vehicles, and equipped with multiport fuel injection (MPFI). This was updated to sequential fuel injection (SFI) in 1986, and initially produced in two forms, one with flat lifters (tappets), and the other with a roller camshaft and lifters. The latter was offered in various models through 1988. Power produced by this engine was:

VIN code B: flat lifters (tappets)
166 hp @ 4400 rpm, 210 ft·lbf (280 N·m) @ 2000 rpm
VIN code 3: roller lifters (tappets)
145 hp @ 4400 rpm, 215 ft·lbf (292 N·m) @ 2000 rpm (1984-1985 MPFI)
180 hp @ 4400 rpm, 235 ft·lbf (319 N·m) @ 2200 rpm (1986-1988 SFI) (LG3)

this says the lg3 like in my 87 had 180 hp??
:btt: 87 blt gn black lg3 (best looking engine imo)

I saw that recently on Wikipedia too. Looks like it needs editing, as that's certainly not how they're rated.
