1969 maro 427 easy install?

in a 1969 maro, will a 427 just drop into the original mounting brackets or does it need to be moddified? will there be any clearance issues with anything, and finally, im seeing it advertised as too many different sides is a 427 a big or small block?

The 427 can be had as both a big block or a modified small block.

or an LS7 $13,999 MSRP

A 427 BB is the same external dimensions as any other BBC. You will need motor mounts and headers.

I've got one sitting in My garage. All You need are big block frame mounts, Motor Mounts, and headers, 350 flywheel will work fine, real easy deal.
