    how do you guys like the TBI 305 engines. I have had some 350's, but never a 305. Also, a '87 Blazer Im looking at, appears to have a NP 208, although when I research it, I find only '88's and up had it. The T-case is definitely not a 205 or 203. What else could it be? Sorry about the newbie questions, but I want to get my truck set up the right way from the get go. Thanks.

    208 cases started in 81, I believe. It's probably a 208. My 84 had one from the factory.

    305s are gutless POS's, but their TBI shares most of its parts with the 350 so it's easily swapped out. Either way, the TBI 305 is one of the most potent of 305s that GM produced, so it's better than most. /forums/images/graemlins/thumb.gif

    Your best investment out of the two engines would surely be the 350 IMO the blazer is just not made to have a 305. Now I know you said you had TBI but you can go ahead and use the 350 its a million times better than the 305 and thats coming from owning a 305 and seeing the difference between the two. Hope this helps o yeah and it sounds like you have a NP208 should say on the back side of the case it also could be a NP241 but unlikely there both good cases to have. Good Luck on your rig

    Not all 305's are POS's as Tim calls them. we had a 78 3/4 ton suburban that had a 2bbl 305 with a 4spd and 3.73's gears and it went all over the dunes and mud. it weighed over 6,000 pounds and had a burnt clutch but it wheeled fine. the motor is now in my wagon with the same tranny, but with a new clutch,LOL.../ I added a comp cam anfd a TBI swap off a 91 IROC. I haven't fired it up yet but it should be plenty for a light rig like mine.
