    The ULTIMATE Coyote vs. LS3 thread.

    Get it started boys and girls... Ford and GM swingers, step in. Both are great, but which is better? Lets make some valid points.

    Darren, This will be an interesting contest of opinion.

    My opinion is I'm tired of seeing all these Ford engines getting stuffed into Bow tie products.

    Hopefully this link will allow you to see the thread.

    This guy is putting a twin turbo LS in a Factory Five Cobra. By the looks of the pictures, he is doing one hell of a job.

    Silver,

    I have to agree with you. The guy has done a lot of work and it is really looking good. He certainly isn't the first to put a Chevy engine in a Cobra and I don't have any problem with that. I think a person should be able to use any make engine they want and not be criticized for it. For crap sake, it isn't like they are taking an original Cobra and stuffing some other make engine in it.

    The LS3 might go down in history as the greatest V8 of all time. Durable, easily modified, makes gobs of power in naturally aspirated form, with turbo(s) or supercharged, parts availability galore, low profile allows it to fit in pretty much anything. I could go on and on...

    Sure it counts! But could you stick a 2013 Boss 302 in a cobra? PS. Welcome to our site Chris. There are a lot of great guys here. Darren

    Gonzo,

    That is a nice looking job that you did there. Nice looking Mustang too. How does it handle with that package and what is the horsepower that you have it set up for? Welcome to the site and post some more pictures.

    Really - Ford vs. Chevy why do't you start with something easy like solving the national debt.

    BTW - spoiler alert - Ford wins

    Thanks Darren!

    We can put a Coyote into just about any car.. The only thing that i don't like about the Coyote is that we are limited to 302 CI & that we do not have bottom end torque.. yes we can Supercharge it but that add weight to already nose heavy Mustang.. Plus the size of the motor.. The LS engine is compact & can get it up to 500 CI..

    Thanks Ron!

    The LS3 is making 600 hp to the crank! The car handles well but we need a better set of shocks.. We wil begetting a set of JRI on it here pertty soon..

    Chris,

    When you get it all set up with the new shocks post some more pictures and let us know how it handles then. That is some serious horsepower and the weight issue is a problem with a lot of good engines if you want to really make the car handle great. I am a Ford person but I do like the Chevy LS engines as they seem to be very good and you can pull all kinds of power from them without adding a lot of weight.

    I will post up the results of shock upgrades here pretty soon!

    This is the type of stuff we like to do... test & tune suspensions .. but also do alot of LS conversions in GM Muscle cars @ my shop..

    I could do a thread on my shop but do not know if that would be okay .. plus where would I post it..

    Here is a engine that I think Darren would like! LS7 .. He should try one of these in his Cobras! We can polish it for him!

    Chris,

    That is great work and you can not only do a thread on your shop and work, but why don't you put an add about it in the Advertisers Forum also. You could do the thread under Cobra Builds and put some pictures in it to show some of your work. From what I have seen your shop does very good work.

    The LS3, stock, at the level youd be pushing it is not a reliable engine. Here is some food for thought:
    http://forums.corvetteforum.com/auto...the-track.html

    Another thing to consider is that the Coyote is in its infancy as a platform, there are many many aftermarket goodies to come in the coming years. The down side of the coyote is the fact that although it is lighter, the center of mass is higher up. From what Ive heard, from a hardcore track perspective, the Coyote is a bulletproof engine.
