    I've read alot on this board about how good a 383 stroker is for wheeling and has spurred my interest. However I currently have a 350 TBI engine in my 91 K5. Would I have to ditch the TBI to go with a 383? or is the TBI adaptable to a 383?

    I belive you can use the TBI on the 383. Might require a chip in the computer, but might not. I'm sure someone will know.

    Yes it is adaptable, though on my 383 i upgraded to Multi-port injection, but used the existing Throttle Body, just ditched the injectors and bolted it on. Go for the 383, out of all the mods I have done to the Jimmy, the 383 is by far the best /forums/images/graemlins/pimp1.gif

    To make a 350 into a 383 first off u have to have your block punch out 30 over. then u have to get a 383 kit witch usually run from 600 up. that comes with cam, pistons, lifters, crank everything basically. the way you get the new stroke is by putting a 400 crank into a 350. witch takes your stroke from around 3.4 i think to 3.75 to 3.80.

    Here is one of those kits i was talkin about

    For the cost of machining a stock 400 crank to fit in a 350 block, you're better off to get an aftermarket crank. Its a better casting, and you can get it with a one-piece seal for the newer blocks.

    383 longblocks are a good value, since they need a good (costly) balance job.
