The Lightning block also has forged pistons and forged crank!

my 98' had a forged crank, along with my 03 engine I bought for parts. Go with a 5.4 and be done. Get good rods, pistons and heads, and you will never have a problem. Being as your using a ported eaton, you wont even be stressing the engine
