dose any one know of any performance parts for 3.4 f bodys or if 3.8 perf parts work on 3.4

The 3.8 and 3.4 are completely different engine and 99% of the parts will not work on the other but there are always the basics that can be done on both like gears and catback system's.

ive done all the easy and cheap stuff that can be bought but dont have the funds to do head work or other major internal mods also tryed free stuff most didnt work

also i know in the 80's the 3.1 was just a stroked 2.8 sameheads and block just wonderd if they did stuff like that on these im gunna price head work and few other mods that a going to have to be custom made if there to much ill probably build a small block

you will have to change 90% of the drivetrain parts to run a Small Blobk chevy/GM engine in there. I suggest you trade the car in for a V8 model if your looking for a street/strip car although with some basic mods you can improve alot.

yep knew all that but trust me i know my way around the garage and have hook up for good cheap used parts and machine work
