7 bolt 6 bolt?

my buddy has a 95 gst fwd with a blown motor (7 bolt right). will a 6 bolt engine bolt right up or is it easier to get a 7 bolt

What is a 6-bolt engine?
What is a 7-bolt engine?
A 6-bolt engine is one that has a 6-bolt flywheel - that is, there are 6 bolts holding the flywheel to the crankshaft. A 7-bolt motor has 7 bolts there.

Along with the flywheel change, there are many other internal changes between the two engines. The crankshafts are different sizes, as are the rods and crankshaft seals. 6-bolt motors have 'big' rods, while 7-bolt engines have 'small' rods. The journal and bearing widths different, although the bearing diameters are the same.

There may also be other changes between the two engines, and the parts are not interchangeable.

I would get a 6 bolt, it will slide in just fine.

Good Luck!! :iceslolan

small modifications required. many, many, many pages of information online about the swap.

This may help you. Good luck
