5.3 to a 383?

^ thats alot of money to build considering you can buy a all forged long block 408 from texas-speed and still save over $1,000

Good thread- say, can I get away with some stock pitons out of a Camaro after I punch out the block to the appropriate bore? I'm gonna 5 axis CNC my 5.3 heads and away I go..................

if you're talking stroker stuff, youre going to have to buy pistons, rods, and a crank no matter what block you put them in. in my opinion, theres no point spending the money to bore your 5.3, then buy the rotating assembly to make a 383. if you're going to buy all this stuff, why not put it all into a 6.0 block and have a 402 or 408, for exactly the same money. theres an easy 50 ft.lbs and 50 hp just in the displacement difference. theres really no good reason to make a 383 out of a 5.3....at least not cost wise. theres no cheap or half assed way to do it. either spend the money on a turbo kit, or on a 6.0 stroker, and stop fu*&ing around.

I rescently build a 383 stroker out of a 5.3 block for Curtd. He has run 9lbs boost on it so far and no problems yet. It actually ended up with 3.9115" bore after proper piston clearencing.
