i have now got my engine,so i'm gonna start making the cradle, so where does the engine sprocket need to be in relation to the diff??.

is it just a case of getting it in line(front to back) and as level as possible??.

also where will the centre prop bearing need to be along the tunnel??.

thanks

The diff should not be aligned with the engine; there should be at least 3% of misaligment; as the Sierra's sits dead center on the transmission tunnel, you may either make the propshaft go up along the tunnel (will help for engine clearence in the end...), or have the engine sprocket to the right of the car ( which would take space from the driver's footwell) as to the left may hit the rail.

should have said, its a live axle car.

hi ray. Are you converting a cec to a bec? I did this, since the footwell is already made you just need to move the engine as far over as you can towards it, before the prop hits the verticle. The centre bearing will help the prop go round the kink in the tunnel.

HI,

not converting, but the chassis is a stuart talyor locost (X Flow engine) chassis.

so which footwell do you move it towards??

what about a centre bearing??.

Ray:

I got decent alignment by positioning my engine about 1/2 to 3/4" from the passenger footwell. The side of the engine is roughly parallel to the upper side chassis rail. look here.

The center bearing goes where it must. I mounted mine vertically; other mount theirs to the lower chassis rails using spacers. On my install, the prop is 3 degrees off from the center bearing back. The front piece runs the angle. Check out around here for center bearing placement pics.
