I resent that one Patrick. I don't and would never do that. Not even.
Some might but not me.

That was not me, it was from my evil twin Natrick.

Does that mean you've already ordered the motor, or is there still an opportunity for us to recommend other engine builders?

Does anyone on here have the setup? Would like some input.

Thanks. Pappy

Pappy, no offense but have you ever driven a 427 Cobra with an FE and say, 450hp or more before? Just asking to get an idea where your head is at and where you are trying to go.

What's the wait time for a Superformance Mark III with a Roush?

Dunno about the engine, but chassis build is 60 days plus shipping. I suspect Roush can have the engine waiting for you.....

That's pretty fast. We ordered a Jeep from the factory and it took almost that long to get it.

Now days, that's like "off the shelf" timing! Pretty amazing. I would have thought much longer for the chassis. Engine? I'm sure they are a stock item.

Makes it all the easier to return it when it breaks.

Not to worry, I've NOT driven anything on the street with LESS than 500 horse since the late 60's and that was probably my first 289's. My last experience's were a 780 ft lbs torque 2010 Shelby GT500 Super Snake, and the last was a 2013 Shelby GT500 converted to a Super Snake by Tim Barth in Rockford, 24lbs boost delivered 890 ft lbs rear wheel torque, everyday driving was 18lbs boost and 700+ rear wheel torque. Notice I don't bother with HP figures, those figures don't twist the rear axles. Nothing like tool'n along about 75, pull the tranny down a gear or two, nail it and in 5 seconds the speedo needle race's past 150mph.

Having more power has always been the draw. Once you get more power learn how to use it you realize why not more, the natural order of things. Getting from point A to B as fast as humanly possible is exactly what these cars are all about for a lot of us.

Thankfully I was lucky enough in life to have been able to own and build an example of the meanest looking hot rods on the planet. Bring on the horsepower & torque!

I would say true up to 450 RWHP, after that anything more is 99% bragging rights and 1% "useful" to the very few who are in a situation where they could actually use more - like a drag strip. If that's your gig, then just build a gasser and be done with it On the street with two guys of equal driving ability, the guy with an aluminum 450 RWHP windsor can run against any size BB/high HP/torque monster and win a 0-100 mph sprint. Make that a race through 20 miles of twisties to your favorite lunch spot, then tell the windsor guy what you want and he'll have the sandwich waiting when you get there.

That's how I assess getting from point A to point B faster

Respectfully, I have to disagree with these statements. For proof just look at CSX3170. He is running a high hp big block that's putting out well over 600 rwhp, pulls 1.45 G's in the corners, accelerates up to 1.2 G's. Pretty amazing stats and balanced performance in a chassis that's not as stiff as most of our Replica's (although his is extremely well sorted). It's all in the set-up.

I'm very fortunate because I can vary my hp setting over a 200 rwhp/tq range by simply turning a dial to control boost levels. This allows me to objectively see where traction thresholds are for any particular day (warm vs cold air temps, road surface quality, etc), and a G-tech RR meter to measure acceleration and handling parameters. Believe me when I say that greater than 450 rwhp/tq on the street is usable. If it wasn't, I would have gotten bored and sold my car years ago. A 40-100 mph roll at around 575 rwhp on an 80 degree day is Nirvana.

And what does that take, 2.5 seconds?

[twin turbo]

Naaah, at that power level 40-100 mph is in the 3's.
Go to about the 38 second mark in this video. My speedometer is a little jerky because my cable was slightly loose.

I hear you BUT,and that's a big word. We live in rural Maine driving the twisties like you mention is impossible around here with traffic and road conditions being what they are.
The off idle torque of a BB is intoxicating not to mention the visual when the hood is lifted, two of the biggest reasons why I chose the 385. Honestly, two cars you speak of setup the same with equal drivers quite sure the results would surprise you. Bottom line is most of us have our cars for one reason to satisfy the desire to own a Cobra the way we have always imagined.
