- - 427W FI or Coyote or Supercharged Coyote (http://www.clubcobra.com/forums/backdraft-racing/142276-427w-fi-coyote-supercharged-coyote.html)

Yes, P38s are Kaase's latest heads for Windsors. Valves are canted, so they look "different". My motor dynoed at 576hp, 5800rpm.....560+ from 5300 to 6600 rpm. 565 lb-ft at 4700 rpm, 560+ lb-ft from 4200 to 5200 rpm. I have a hydraulic lifter motor, 248/256 duration @0.050" lift, 0.636/0.620" lift at valve. tight 110 deg lobe separation. These heads move a lot of air, and will really punch up some numbers with a higher rpm solid lifter motor. I wanted a more streetable motor so kept it a little calmer.

My favorite question - I'm interesting in a car to drive twisties - so weight is very important.

What is the weight difference?
Coyote vs 427 vs Windsor vs Coyote SC

In stock trim, the 351W weighs in around 510-550. The Coyote is about 430-450. The Ford 427 big block FE motor is around 650 pounds.

I vote for the lighter weight aluminum 427 stroker based on the 351 that gives you 600+ hp with the same weight as the 351. For ease of turn the key and drive the modern drivetrain is great but give or take 100 pounds you will never notice

I added camber plates and a little stiffer spring to the front as well as upgraded all 4 shocks. I upgraded the manual steering as well. I remember your posts about the weight balancing. I have an appointment next Wednesday with a custom shop that sets up Porsche racing suspensions. I am going to have them set up the alignment and weight balance the car. My car has a Roush 427r. I can't wait to see how it turns out.

Fred,

Funny, I just tried to install camber plates last night. Turns out that I need camber nuts (threaded sleeve/nut) because the top part of the stock KYB 361005 shock inserts are too short. What upgrade front shocks and springs are you using? Also, did you have to trim the camber plates to fit in the tower, and what manual rack are you using?

I replaced them with the KYB's. Same ones you have and I also thought the shock inserts were short. I have the stock rack. Here's the problem, if you got the Camber kit from Iconic, they probably shipped it to you assembled but it's not assembled in the manner it goes on the car. It's all wrong. It drove me crazy til myself and another fellow who posts here figured it out. I tried putting it in every which way and even considered modifying them. Finally figured it out by taking them apart. Take a look at my gallery pictures as there are pictures on there as to how they go together. Good luck.

Has anyone put a Predator in one of these cars? Would it fit?
