just curious would this bolt right into my 87 fox without modifications to the mounts

RyanH20

  • No. There would be some mount, frame, and maybe fender modifications needed to bolt this up to the engine bay. But your pony would scream so I would also suggest doing a full rebuild, including trans, differential, and frame rebuild/strengthening.

Forced induction possible? I know the description here is all about keeping this sucker naturally aspirated, but is there any chance of boosting power with a super/turbo charger?

ShouldaGotTheGT

  • An engine is an engine is an engine is an engine. You can always put boost to any engine. This particular engine is at 10.4-1 compression so I wouldn't run much boost, but the new coyotes are at 11-1 and they make superchargers for them. So I say go for it. If you really want to run crazy amounts of boost I would either change heads or get some new pistons go drop the compression.

Swapping engine I'm young and new to muscle cars. I currently have a 09 pony package v6 mustang and would like to do a engine swap with a v8. Is this possible with a v6 mustang and if so, what v8 should I put in it? I would like to do a couple add ons to the v8. Also, what all would I have to buy to prepare for the v8? New transmission or anything?

Klg1992

  • Yes it is possible. You will need to change out your K-member for one designed to hold the V8 you choose, Maximum Motorsports will either have one or they can build one for you and they are the only manufacturer I know of that states that their K-members are designed for street use. Do not use a cheaper "race only" K-member as they have been known to fail under street driving conditions. The guys here at AM can help you get the one you need I am sure. Your choices are the older style pushrod V8's or the newer mod motor V8's. That part is up to you of course, but my preference is for the older pushrod engines because parts are cheaper and they are much easier to work on. Each engine type will require it's own style of wiring harness and computer changes if you keep them fuel injected. You will also require a transmission and rear end designed for the extra torque your V8 will put out. Those choices will also need to be sufficiently built to withstand the HP and TQ levels you will desire in the future, so think ahead if you plan lots of mods and choose these components wisely. Good luck.

peg

  • The Ford Performance 427ci 535HP Rear Sump Crate Engine is perfect for Fox body mustangs, however will fit in other models with a lot of custom modifications that will be needed to make this motor fit.

will this 427 engine fit in my 03 cobra 4.6 how much of a problem will take to install

gasman

  • The Ford Performance 427ci 535HP Rear Sump Crate Engine will require a decent amount of components to fit properly in your vehicle. This would be a very intuitive job, and we would recommend an experience speed shop for this install.

I am building a 1970 Mustang Mach 1 and considering this engine and the 450HP version of the 427ci. my question is will this engine fit the 1970 mustang without modification? Will it support at Ford AOD transmission with 3.70 rearend gears? How does this engine height compare to the original 315 Cleveland engine to support the original "shaker ran air" hood? Best for street/cruise use 535hp or 450hp version? Thanks,

rfp23

  • I think when anyone is planning such a radical change to an older car, mods have to be part of their thinking. That being said, the 1970 Mustang motors included both the 428 429 motors, so it seems reasonable to believe the 427 will fit as well. Drop right in without any modifications? That's difficult to say exactly. AOD tranny? I think you will want to look closer at a built C4 or C6 tranny to handle this engine. I think both engines will provide a good strip/street engine, if you don't plan to "drag main" every Saturday night. Height of the engine for a Shaker hood should be fine, but again, it depends on some variables there. All of this is not an exact science, so if you think you can just drop go, you may be under some misguided illusions.

Word on The Street

I've had my 2012 Mustang for one month now and have made four separate purchases so far. American Muscle is by far, and I have browsed the web on other sites, the best for parts, add-ons or anything Mustang for that matter. My purchases were made online but I had a question on one of them so I called customer service. Customer service could not have been better. As a Pennsylvania resident I am proud to support a (PA) operated business and I recommend them to anyone seeking a great experience in service and merchandise. I can.t wait till my next order arrives. Thank you American Muscle.

After owning several other Mustangs including 99 Cobra and a bunch of Fox body’s I finally decided it was time for a new car. One that would be reliable, fast, and be able to cruise with the AC on in the summer.  When the S550 platform came out I knew I had to have one.
