Bore size on 382 stroker motor?? Hey guys need some help here. I was lookin into either doin a 382 or 383 stroker kit. I was wonderin wut preperation I would need to do the block. Do I need to bore out the block to make room for bigger pistons or are they the same? Im sorry for all the questions. Im just trying to figure out wut all I need to know before i jump into all this. Also which one would ya do the 382 or 383. And any other things I might need to know please let me know.

Thanks for the info. Let me ask this then. Im prolly goin to go with a procharger would that go better with just heads an cam or a 402. This will be a daily driver now. So I have to keep that in mind too. Thanks for all the help.

I think you are better off going with a 347 or and iron block 408 for big boost.

Tony Mamo is making well over 600 hp with the 383 in his C5. Look for chassis dyno numbers in the near future.

a 383 can make more power, more torque, and do it more with more reliability and keep it more streetable than a crazy aggressive h/c car. 383's make power all day long, starting down low. crazy 346's are all mid-high to high end.

Just my opinion that a stroker is so close to a 402 or 408 in price that you might as well just do it. I just see them as a waste of money. As far as what this guy is concerned, for boost I would go iron block for the best reliabilty.

But yes..383s are obsolete with the 402s/408s being more bang for the buck now.

Nothing wrong with a 383. I put down 497/460 threw a 9in with 4.11s. would be well over 500 if not for the rearend. As stated above, just got to pick the right combo.
Good luck
