427 or coyote?

We are about to find out what the XS will do. The guys at Vintage are about to do the final tune on my Backdraft with aluminator XS with Lund Racing tune maybe this week. Jay and Brian are the only people that can speak to seat of the pants feel since they are the only ones that have driven a Cobra powered by this engine. Should no more by end of the week. Hoping for around 500rwhp.

Good timing on my question. Thanks for the response. I will be interested to hear the results!

Couldn't ask for a better tuner! Just curious why did you go with the XS instead of the Boss motor?

If I'm not mistaken the XS is the replacement for the BOSS. I was initially going to do a supercharged coyote. Was not enough room under the hood to do AC and the supercharger. Jay suggested the XS. Higher revving and he figured we could get similar HP with it N/A. Also, we would have the first one off the line that is kinda cool. To hear them talk it is awesome to drive. Can't wait to find out for myself.

The XS has more cobra jet parts and is rated higher out of the box than the Boss is from what I can tell.

Edit: I see the Boss motor is now discontinued. My mistake.

A call to Jay at Vintage Motorsports and he could answer all your questions.
They do everything from old school to modern. Tell him what you want and he can help you decide what is the best direction to go.

Jay at Vintage built my last car and is going to be building my next also (great guy) I've been talking with him every other day...and I don't want to keep driving him nuts lol. Thanks for all your input! Very helpful

Ps I've been admiring the photos of your car for the past 3 weeks on Jay's website...Bad ass!!! Enjoy!!! My last build was #1012 on jays website FYI

Thanks for the compliment on the car. I know how you feel on the driving them nuts thing. I try not to call them to much but it is hard not to call everyday to find out what is new. The closer the car gets to getting done the harder it gets. Have you ordered your new one yet or are you still figuring out what you want?

Toddl 500rwhp is overly optimistic seeing that the crank hp is just over 500.
