I've been thinking about building my Lt1 to a 383 Stroker. Any ideas on how much that would cost?

 

1500 for the kit plus labor for instalation will vary depending on mechanic id guess probably 1500-2000 in labor i could be wrong though im going off what a friend payed for labor for a stroker kit on a 4 banger

 

I would guess 3500 - 4000 total - you are going to need to hone for the new rings, add a gasket set, tank the block etc. While you have it out might want to go with a different cam too - maybe add a little more if you do. About 600 savings if you don't use a forged crank and high-performance rods / pistons I would guess. Less if you are pulling the motor and doing the tear down / assembly. Just a good forged rotating assembly will run 1800-1900 from Scat.

 

as u can tell it all depends on what u use and what u need or want. if memory serves me right the block will need to be boared 30 over. depending on any boost additions it may also be a good idea to splay the mains to 4 bolt. more money. its very easy to pump 6k into a motor.

 

When talking performance, how much of an advantage would the 383 Stroker be over just the LT1?

 

let me start by asking why you think you need a stroker motor?

 

i hate this question. it'll most likely cost $100k. but for real like they said it depends wat parts you use and how much of the work you do. i have a lot into my stroker and its not even all the best parts (best as in brand) and we did most of the work. call a local reputable machine shop and find out from them. thats your best bet. a stroker motor wont be much more performance if you dont do things like cam and heads. but strokers r more torquey motors

 

What are the con's of making it a stroker motor?

 

i didn't say there were any cons...just curious why he thinks he NEEDS a stroker. most people would be amazed at how much power you can make with a stock bottom end

 

open the door to power and the bug will bite and not let go =P
