dimension difference between big and small block chevy
besides the weight of the big block is the overall width or length different between them. car had a small block with front plate and looking to go bigblock. thanks

They are a lot wider. It is the cylinder heads more so than the block.
|
They are also @ 3-4" longer in front of motor mounts. I switched mine a couple seasons ago & everything bolts up the same except the front is now closer to the radiator.
|
so the clearance to the firewall is the same its the front that changes. my car came with a small block plate. do i alter that or just buy a new one

Just thinking, sometimes you are able to cut out the front plate to accomodate the BB. sometimes not depends how the first is made.
