We're building a 1965 Mercury Comet and have decided we definitely want to put a Ford modular Mustang crate engine in it. We're consideringthree options:

(1) the 4.6L DOHC, direct replacement for the 03-04 Mach 1, with or without a supercharger;

(2) the 5.0L "Cammer" engine, normally aspirated; or

(3) the already-supercharged 20075.4 L SVT Mustang Cobra engine.

I believe the following is some basic info on the three choices:

#1 = 305 HP (without supercharger), 400+HP (with supercharger), 320 ft/lbs torque, aluminum block?
#2 = 400+ HP (normally aspirated), 365 ft/lbs torque, aluminum/alloy block
#3 = 500 HP (with supercharger), 480 ft/lbs torque, iron block

#1 would be the safest option given its wide use. #2 would be great because you don't see a lot of people using that engine (it is not in any production models) and because it has a lot of power with normal breathing.#3 would be really cool because it's the newest engine and has gobs of power (but I also understand the engine is quite heavy given the iron block).

I realize the car is not a Mustang, but it would be really great to get people's views on which is the best choice. Also, I know people would usually includecomments about cost(and some might say pick an entirely different engine from the three options).But, if you had to choose one of the three options and if you were offered all three engines at the same price, which would you choose and why?

Thanks in advance for your help!

#2 cause "cammer" just sounds cool.... add a supercharger to it later

if you want a s/c engine think about a 03-04 cobra"terminator" engine. new they are about $10K but i have seen some low mileage engines out of wrecks for $5k.
you are going to modify the shock towers aren't you? thats one of those cars that is hard to get anything other than a windsor in due to space. fatman makes a complete front subframe for those chassis. that might help you get some room for a 4v modular to fit.

#1 would be nice and easily attainable. #2 would be sexy as hell just because of what it is, but #3 would be the best bet. With a pulley swap/intake/tune on that thing you could be making 650 horsepower and make up for all that extra weight. That is a VERY strong motor and you don't really have to worry at all about it blowing even with a great deal more than the stock power. If it wont just rip your pocket wide open, that is what i would reccomend, but keep in mind it will be ALOT more expensive than #1.

dude get the 5.0 cammer motor....once u get that thing with a supercharger on it....dynos will only tell what it can do

Stroked 408 with a blower...... but i like option 2 also.

is there anyone shoving V10's in older mustangs yet? i mean, if you can fit a wide motor (4.6's and big blocks) and some came with pretty long motors (straight 6's) why not go for a V10 out of a pickup/van?

I dunno what kinda power they made - but the thought of a V10 powered stang with, lets say a 6 speed stick.... that just SOUNDS badass

Thanks for everone's comments -- very very helpful so far.

It seems like I'm going to make the leap and do either #2 (Cammer 5.0) or #3 (2007 SVT 5.4). If I do #2, it will not be supercharged (at least for now). So, boiling it down to these two choices only, assuming same cost, which one would you choose and why? The "why" is very important to me -- in other words, what are the reasons to choose #2 or #3 . . . and you all (Mustang owners) are the best people to get advice from on this question!

By the way, the 1965 Cometwill be getting a full new Art Morrison Max G chassis -- so it should be able to handle the extra power from whichever of these two engines I choose.

Keep the comments coming -- the more info I get, the better!

Again, the two choices are:

#2 the 5.0L "Cammer" engine, normally aspirated, 400+ HP (normally aspirated), 365 ft/lbs torque, aluminum/alloy block; or

#3 the already-supercharged 20075.4 L SVT Mustang Cobra engine,500 HP (with supercharger), 480 ft/lbs torque, iron block

cammer ftw, i wouldnt go with the gt500 engine for some reasons like not alot of parts for it yet, expensive to modify, and some more downsides. YES it IS a powerful capable engine but i dont think it will be the best bang for the buck.
