Lykins Motorsports 347SBF Build...

The pond blocks will take a 4.375 stroke without issue. 4.500 stroke cranks are generally reserved for cammers because the rods hit the camshaft. The cast iron pond block will take a larger overbore.

Honestly, I have never seen the need for a Shelby block, unless the name is important.

Thanks Brent!

Darn, should went with a 4.375" stoke in mine. That would have helped my HP deficient FE.

I'm spoiled by my LS7...

Throw some more cam and head at it, it will wake up more.
