hiya im putting a 440 turbo lump into a 340, just wondered if i need to use the 340 clutch and flywheel or if i can use the 440 clutch and flywheel.

Have a search, it's been covered a lot. Is your tubby block an FT or an FTM, and does it have a big or small flywheel?

Normaly use turbo flywheel and pressure plate and then use 340 realeasse bearing and friction plate.

found some things about it , cheers for your help guys
