I wanted to know on a 3800 swap why do u use a Camaro flywheel and cut the clutch matting surfs down. Why not use the Fiero 2.8 flywheel and grind the weights off? Because that is what u do for a 3.4 conversion.

The 3800 has 8 bolts to mount it the the crank and the 2.8/3.4 has 6.

------------------
Go Army.

3800 engines are externally balanced just like some 2.8's, and the external balance is different (weight). Also, all mid-90's and later 3800's have an 8-bolt flywheel to crankshaft mounting bolt pattern while the 2.8 only has 6. There's no good way to change a 6-hole flywheel to accommodate 8 holes without creating a lot of issues for yourself. To complicate matters further, the 8 bolt holes used in the 3800 cranks/flywheels are not evenly spaced - GM did this so the flywheel or flexplate could only be installed one way correctly (because of the external counter balance weight on the flywheel needing to be in a certain position in relation to crank position).

Your answer was better ...

I'm still faster lol. (Don't hate)

Thank U for the INFO. I'm going to get my 3800 next week and want to have most of the parts on hand. So do U use Fiero clutch and pressure plate? Or Fiero clutch and Camaro pressure plate?

You want a clutch and pressure plate for the transmission you are using.
