Difference = 120-93 = 27 lbs.

I'll betcha most of us around here carry 27 extra lbs of fat on their bodies that, if lost, would make that difference negligible.

No, it would still be 27 pounds, BB guys go on a diet, then the SM block guys go on a diet - we ain't giving you nutt'in

For this debate to really quantify weight difference, need to hang both crate motors from a hydra set, the block is not the only discriminator here.

Yes there out their. I know of 2 the are very good. The most common issue with IR manifolds is idle and partial power. The runners need to be balanced very close to each other. ( pulling the exact same vacuum, and all blades opening at the same time and traveling within the same Arc). If the runners are not balanced equally then a popping sounding will be heard, and or EFI computer will struggle to adjust the Air fuel ratio. Even the best computer will fail unless U follow my advise.
So what does all this mean? once the engine is in the CAR, take it to a good tuner and let him show u how to do it. It will require small adjustments every so often. It may take several hours (first time) repetitively adjusting each blade until all are balanced.


MJJ a large no. of cobra owners wish they would have asked for more horsepower when they had their engines built. Why not build for more power and tune several different MAPs. 1 detuned map (large amount of timing and fuel pulled) and 1 more VISCERAL map.

A windsor will make an easy 550 to 580 HP (how do i know?? see link) and be very streetable, and the stack will make it a joy to drive.


463 IR Windsor


MJJ feel free to send me a PM if i can help.

Research shows that drivers of FE-powered Cobras have a lower % of body-fat than any other Cobra owners with Mods, Windsors or 385-series.

No, the block is not the only part that has a weight difference, but the rest can't amount to much. Certainly nothing significant.

Yes, Yes, Yes, the Windsor is lighter that the FE... So what...?

I'm guessing a miata engine is lighter than the Windsor, but you don't see many entertaining that in a cobra. You've got to draw the line somewhere, and some draw it at the FE for an SC...

Now if we were building a FIA or Slabside cobra, then we could talk Windsor...
Else, this discussion is folly

...and the OP will chose whatever tickles his fancy anyway, and happily drive away into the sunset.

Go back and read OP's introductory post, you just trumped patrickt for the "Captain Dumb" award lol.

... add deaf and blind to that as well. We FE owners can neither hear, speak, nor see anything other than an FE in a 427 car.

Enjoy your day.

I have heard that you have your PHD. in Cobraology? I think that must be true , because you Pile. it High. and Deep
