So is this the ungine used in the 4.3 S-10s and Blazers around 1998-2000 or so? If not those years, then which ones? Does the intake actually look like an :T1 intake, and all the accessories and stuff are the same, including the Optispark? If that's the case, then I need to guy pop the hood of a Blazer! Let me know.

 

The "baby LT1" (265ci) was only used in the 94-96 Caprice/Roadmaster/Fleetwoods, just like the real (350ci) LT1. To my knowledge, it was never used in any trucks. The 4.3L S-10 Blazer was a V6.

Look at this article for info on the similarities and differences between the 265 and the 350. They should look very similar.

 

i am not sure on this but i think the 265 must of been standard in a caprice and a 350 a option. I bought the motor i built for my car out of a caprice and i checked the casting number on the block not the 327 but the actual part number and it was a 350. So i don't know how they decided which car got what type of engine unless it was a option.

 

oh, OK. I thought maybe it was a V6 because of the 4.3L of displacement. I was wondering why they said the heads would bolt up.
