i'm trying to do a rebuilt on my 94 ls engine, and i wanted to know if the GSR engine parts ALL fit the 94 ls engine? i heard people say that they are all the same engines and that the GSR engine parts fit the LS engine?

 

What parts you talking bout son?

 

some parts are interchangeable completely and others are not 100% interchangeable even though they will fit, the engine may not run right and i'm nowhere near 100% sure if i'm right about some being interchangeable, but believe me this panel is a good place to find out....welcome to han

 

The stroke on an LS engine is slightly longer than that of a GSR. Be sure to use LS rods, crank, & pistons. Certain misc. stuff is interchangeable, but to save yourself the trouble I would just use LS parts.

Using GSR crank, connecting rods and pistons will only reduce your displacement and cost your more.

 

thanks that was basicly what i needed to know...(pistons, rods, cranks, valves, springs, retainers, etc.)
