I believe the modular motor's days are numbered. The new V8 motor Ford is building is not based on the modular platform. It's a motor developed for the new Jaguar.

The modular can't be made much bigger because of the bore spacing. It's at it's maximum piston size at the moment so the only way to increase the capacity is to further increase the stroke.

I'm not saying the modular is a bad motor. Our recent track day was cleaned up by a N/A 4.6 powered Robnell Cobra. It's just an expensive motor to improve.

An Iron block 5.4 quad cam weighs about 279KG which is about 99KG more than the LS series motor. Add a blower and intercooler to it and you've bolted on another 40 or 50KG.

Guys here running a stock L76 6.0 motor can do the basics with a new cam and springs and a retune of the ECU and they are making over 400 HP at the rear wheels. That's some great bang for your buck especially when you can buy a new L76 in the crate for under $5K
