What would be the general price of a 383 stroker motor. My 79Z dosent have the original motor so i am wonderin what kind of engine to put in it. Right now it has a 350 4-bolt main. I am thinking of putting in a 383. Unless anyone has any other ideas for a motor to put in it. thanks.

work with what you got, build the 383

It was a possibility that i was going to build it. Thanks. What all would i need to change to rebuild the 350 4-bolt main?

to make it a 383 you will need to buy a 3.75 stroke crank or get one out of a 400 chevy. You will need 383 pistons and you can use the stock 5.7 rods.
I forgot to ask what is your HP/TQ needs? That will considerably effect the cost of this build

Just to be sure you are talking about changing the 350 to a 383. If you are that would be alot easier for me than finding a 383 myself. I would like somewhere around 300-375 horsepower. And I not so sure about torque. About how much would the 3.75 stroke crank cost. Right now i am just going to write this all down cause in the near future it will be rebilt. Do you know most or all of the steps to change it to a 383? Thank you for all of your help.

There are a number of Stroker kits available, most cost around a grand depending on the quality of parts used.

Do a search on Summitracing and you should be able to find a few kits easily.

Go to www.cnc-motorsports.com (http://www.cnc-motorsports.com)
they have some great deals. Since your in the 300 hp range you will have no problems using a cast crank which will run new for around $200 (SCAT 9000) and you can use hyperuetic pistons and the rods you already have. This build wont break the bank. You can also get complete roating assembly for around $700-$800 that is with forged pistons too!

Building a 383 is no real rocket science, but if your not already familiar with the small block, maybe this isn't a good road to go down. Taking a grinder to the block and the rod bolts isn't for the faint of heart. Something about it tells you "this can't be right" and it's NOT. No one at GM ever intended the 350 block to accept the 3.75" stroke crank. And it rightfully doesn't! You have to clearance the block just so the assembly will even go into the casting, then you have to clearance the rod shoulders and bolts to they will clear the cam, you MUST check every item in the asembly to make sure you have adaquite clearance. There is an old Murphy's law of mechanical relationship that goes like this,,, "opposing components attempting to occupy the same space, at the same time, generally end up occupying adjoining space at the bottom of the oil pan". NOTHING brings you closer to that saying than the stroker motor. All I'm getting at is it's not as simple as tossing a crank and pistons at the block,,, everything about the stroker make it a challange.

With that said,,, is it worth it? WITH OUT A DOUBT!!!!! If your willing to take the time and make the effort to build the motor right the first time, you will never look back. The added torque is simple AUSOME. I can't say as I've ever heard of ANYONE who was disappointed with the results of making their 350 into a 383.

Just for reference the GM Performance ZZ383/425hp is $4800 from Scoggin Dickey

thank yall for all of your help. I am sure this project will go fast now. Thanks again.
