Differences in Motor between R and non-R

[96cobra]

According to Ford Performance yesterday this is not fake news at all.

While at the NMRA/NMCA Super Bowl yesterday I was informed by the Ford Performance Rep. the GT350R Timing Chain is not the same as the GT350 and is available in their catalog.

Why do the threads with no value go the longest.

How I wish you had a name.

FRP removed the verbage for the chain listing that implied that there was a difference in chains between the R and the non-R. It now states that the chains for the GT350, R or not, are 10% stronger than that of the "5.0 Liter Coyote engine."

Numerous individuals sent them correspondence on the matter. I've seen back and forth from the director at FRP that (in essence) states that it was indeed an error and was to be corrected (which it was).

Funny you said this. I saw this thread at the top and asked myself "There's little to talk about, why is this still going."

My fault, curiosity got the best of me. :doh:

I realize this is dragging on, but reminds me of a few years back when BMW was building the lightweight E36 M3 and they acknowledged that the engines that produced slightly more power when initially tested did get steered into the limited edition lightweight (LTW) models. The difference was minimal at best but it was still a difference

Except there is "LITERALLY" no difference in the 5.2L VooDoo engines as there is only one.

No, it was not two different engines, it was coming off of the same assembly lines but certain ones, just due to production tolerances, would inevitably make more power than others. The ones that did went to the lightweight.

The "Wednesday" engines.

You're telling me every E36 M3 engine on the production line was strapped to an engine dyno and run in?

They're Germans. Their engineering prowess is so high they can tell the better engines just by looking at them.

Regarding the chain debacle, I had a good friend in the Ford pipeline send me a couple of photos that depict one of the differences anyway between a GT350/R chain and a production Coyote chain. Ford polishes the chains where they ride on the guides on the GT350/R. Not my photos so go easy on the potato cam hate.

He's inquiring with engineering at Ford about any specification differences.

I can imagine that there are other additional "tweaks" to accommodate the increased RPM, which it seems obvious is the reason for the chain polishing.

There are a few. Remember this is with respect to both the GT350/R in comparison to the 5.0 Coyote engine used in the Mustang GT and not between a regular GT350 and an R model.
