what do i need to make my stock lt1 into a 355 stroker? what kind of hp would it be runnin?

 

355 is just a stock Block Bored .030 over wich gets u another 5ci

I think you thinking about a 383 stroker. You whould need a .030 bore. a 3.750 stroke crank. and a 5.7 or 6in rod depending on what piston you are using. You whoudl also need to have your block machined for the bigger stoke crank

 

im not confused i just need ed to know if i needed a longer rod and stuff like that because i looked at what i need for a 383 and its way out of my budget for now.

but thanks for the information

 

A Chevrolet 350 is a 4.00" bore block with 3.48" stroke crank and 5.7" rods. A 355 is achieved by a .030" overbore on the block (4.030"). It is possible to build a 6" rod (or longer) 355, but you'll need pistons with a different pin location.
Long rods USUALLY make more power, but they're not very "nitrous friendly" because the rings are usually moved closer together when the pin is moved up.

Rod length doesn't affect cubic inches. Bore and crank stroke are the only things that will affect displacement.

Let's add in the simple equation for finding cubes......


Bore x Bore x Stroke x # of cylinders x .7854 = cubes

4.00 x 4.00 x 3.48 x 8 x .7854 =349.848 cubes
4.03 x 4.03 x 3.48 x 8 x .7854 =355.115 cubes


Now for the 383 vs. 355 question. You need a new crank to get to a 383 but for a 355 you can resuse the stock crank, and rods if you want, but you might as well put in new rods and pistons.
