Can I turn my 350 tpi bored .60 over into a 383 stroker? I've been told that I can, but I don't really know the first thing to do...I searched google and I couldnt find anything about it besides pages telling how fast they were in their 383 strokers..Can anyone help or does anyone have a link for me?

 

It actually wouldn't be a 383, it would actually equate to a 388 if I remember correctly. The only difference between a 383 and a 355 is the crank. To make a 383/388 is you will have to bore the cylinder out .030 or .060 in your case and add either a 400 crank or an aftermarket 383 crank and buy 383 pistons. Here is a basic list of parts for my 383.

350 block bored .030 over
5.7" LT1 rods
383 pistons (speed-pro coated skirts)
Scat 9000 crank (1 piece rear main seal 383 crank)

Those are the basic parts along with possibly notching the block to make sure the crank and rods clear everything. Also try searching for stroker motor that might yeild you more results or just call a local machine shop and ask them, I am sure they will answer all of your questions.

Almost forgot you will need a new balancer as well.

 

Yup 388; get a balanced rotating assembly to make it a little easier on yourself; usually come with pistons, rings, rods, crank, bearings, flex plate and balancer.

 

Thanks, I just wasn't really positive that I could turn my TPI into a stroker engine cuz some dude i know was trying to tell me I couldn't, maybe he just doesnt want me to kick his LT1's ***. If I were to do this to my 350 tpi, would i be a lot faster? and isnt the main goal of the stroker engine to get a higher compression ratio??

 

I went with my L98 Block. Eagle Crank, 5.7 Eagle H beams, and SpeedPro Pistons. Block went 30 over and I had main studs installed and had it align honed. Its at about 10:3:1 with 64CC heads now.

 

The main benefit from a stroker is increased torq, your hp won't go up much if you keep the same set up as a 350 but your torq will make a nice jump, it also will shift you power curve down. You can use a longer duration cam thus netting more hp potential.

 

I dont see the correct detail above.

A 383 is a 350 block (stock bore is 4.00") bored "30 over" which gets you a bore of 4.030". The stroke of the crank is 3.75". When you correctly multiply that out, you get 383 cu.in.

The rod length can be either 5.7" (stock) or 5.85", or 6.00". Picking a specific rod length determines the compression heigth of the piston.

The addition of half of the stroke PLUS rod length PLUS piston compression heigth must equal 9.000". This will put the top of the piston while at TDC 0.020" 'down in the hole'.
The stock deck heigth is 9.020",,, some people have the block 'decked', so to reduce the amount the piston top is down in the hole. This has alot to do with the compression ratio.

If you have a 350 block that is already bored 060 over, then you get a 388, as mentioned above.

BTW: Kylez28, get a good book a Chevy SBCs, I bought several books that helped me out alot.
