Partial list of course, the decision is trivial

Just for Popcorn...

How about we throw the LS7 in the mix.

427W: "Weighs approx. 200lbs. less than a Big Block 427FE."

LS7 weighs approx 400 pounds (458 pounds fully trimmed) which is about 120 pounds lighter than an iron head 351W based motor. However the gap is a little closer if you run alloy heads.

427W: "Improved internals over factory 351w. (Forged Connecting Rods, Crank and Pistons)"

LS7 has Titanium con rods from the factory, 6 bolt main bearing caps, factory dry sump etc.

427W "Same Dimensions as 351w."

LS7: Smaller than 351W

427W "Approx. 2-3 inches less in Width and Height than 427FE."

LS7: Approx. 2-3 inches less in Width and Height than 351W

427W "Huge Torque increase over factory 351 engine (500+lbs. when built properly)"

LS7: 475ft/lbs factory stock. This is a conservative factory rating. Dyno tests of stock crate engines have shown this number to be closer to 500. Add a cam and that number will jump to well over 500ft/lbs and 600+ HP.

427W: "Runs Cooler than a Big Block Ford."

LS7: designed to run on pump gas, drive to work during the week and then clean up at the track on the weekend. Comes with a factory warranty too.

427W "Vehicle Handles and Corners Better than a Big Block Engine.
Just as Fast or Faster 0-60 or 0-100mph times than a Big Block."

LS7: Umm... Have you seen the times they run them round the Nuremberg Ring?

427W: "Still have the bragging rights of a 427 cubic inch engine under the hood."

LS7: "Still have the bragging rights of a 427 cubic inch engine under the hood."

Let the arguing begin... LOL!!
