Big Block engine offset
« on: October 02, 2012, 09:06:48 PM »
Hi guy's !

I noticed in your engine/frame mount that you mentioned that Big Blocks were moved to the passenger side by 1".

This is actually only 1/2".  If you measure from the carburetor stud to each fender you should get approximately 24 3/4" driver's side and 25 3/4" on the passenger side.  The difference in your measurements is 1", but the engine is only moved off of center 1/2". (1/2" offset)

Example: Distance from center to each fender = approx. 25 1/4 "  Add 1/2" to driver's side =25 3/4". Subtract 1/2" from passenger side = 24 3/4"

This 1/2" offset matches the transmission crossmembers 1/2" offset .  The transmission crossmember also moves the transmission mount 3/4" forward of the small blocks location.

The BB engine frame mounts also move the engine forward that 3/4", also.

Thanks Guys !

Tom

If you read it the key word is "offset" not moved.
