4v heads on 2v motor??


OK, so i think i am correct with wanting to put a set of 4v heads on my 4.6 2v block. I understand i need to switch timing gears etc. But for cams, im looking to go perfomance stage 2 cams from american muscle. But i would need cobra cams correct? and for intake i would need to shop for 94-98 intakes correct? just trying to make sure i have everything correct before i order the wrong parts. all in all parts will be cams, heads, intake, throttle body, tune, possibly forged rotating assembly.

You need to consider your compression ratio as well. By putting on 4v heads on the stock shortblock, your compression ratio will drop. You'll also need a 4v timing cover too.

What year heads are you using? The Cobra intake changed around 99 I think. I don't know if the heads were different. You'll also need a different exhaust.

Edit: And as has been said many times before, why spend that kindof coin on a head swap when you can spend it on go-fast parts for your 2V. These things can be made to run just as fast and faster than the 4V.

Doing the swap would only be worth it if you had a twin screw sc. Even then your still limited on hp

i agree with nickpholAandP make the 2v fast. keep it 2v.. 4v sounds cool on paper.. but after looking into it, its just a headache.

If you are starting with a 4v then you do get more power for the money than a 2v. But you're not. You are going to spend the money first to make it a 4v and then spend additional money to make it faster. You would be better off getting a supercharger or a turbo.

with a 5-6k budget id get an aviator motor, open it up and replace the internals. Maybe some mild head work before throwing it back together depending on how much you have left in your budget. Whichever way you go, it doesn't matter what you do to the top of the motor, if you keep the stock bottom end your hp will be limited to ~400hp. That can be made several different ways within 5-6k without ever taking the heads off of a 2v 4.6.

Buy the compleat motor and swap it in. Just using the heads will drop your cr to 8.5-1. Your going to make less power with that head swap

If you want the most power for your money. Throw a big block ford in there lol. These tiny motors take a lot of money to go fast.

DickH is right bro, especially since your leavin the bottom end stock.. the potential of your newly found 4v heads will only be unlocked if you forge the bottom end. and if your gonna spend the bones to get the 4v heads and then the forged bottom end.. youll still be around 300-350 hp without a nice power adder. i say ditch the 4v heads. get free flowing 2v heads, forge the motor, hit it with a procharger and pump out 550hp. make cobras feel insecure when a nice lil GT whoops some ass.

That's what I'm talking about! But in all honesty I could build that for about $2500 less.

This. 03/04 aviator motors can be had for around 2k from lkq but I bet you could find one even cheaper than that if you looked hard enough.

HAHAHAHA. I'm doing a 2V build right now and with my rotating assembly, heads, and miscellaneous parts I'm at $5k. You just have to come to grips with the fact that Fords cost a lot more to make fast. If you think you're going to spend LESS going with a 4V setup you are sadly mistaken my friend. Like someone else said, you will spend your projected budget just getting a stock 4V in there, and then some guy like me with faith in 2V's will come along and wax you in a race cause he put the money where it helped.

Stock 4v heads on a stock 2v block makes for the heaviest possible 4.6 you can build. There's a reason that Ford spent the extra money to put an aluminum block under those heads.

if you want to be a dyno queen dump all 6k into the motor. if you want to be a beast and run some serous track times do this.

1. 31 sline diff, axles and gears with a rebuild kit (750 for parts)
2. (5 speed) built t45 or built 3650 (1800) tko600 (2600 better) clutch (450)
3. full drag suspention in the back (1000)
4. 125 shot nitrous used (600)
5. 15x10 wheels with slicks (600)

you can hang out with your buddies and talk all day how much power your car makes or you can take my advice and be the one at the track showing your buddies how its done.

Truer words have never been spoken. Take a look at Bulloch27. He's got a FAST car and it's pretty much all stock. Just a few bolt ons and lots of suspension work with a little juice.

OP, so in the few minutes that have passed since you opened this thread you have learned that putting 4V heads on is no good so you researched a little and found a nice rotating assembly. Just imagine what you could find if you spent a week looking for parts instead of being kindof impulsive. Look at companies like ModMax or MMR for rotating assemblies. They have great parts at even cheaper prices than what you found. I've been researching my engine build for probably two months now and just when I think I've found the best deal I will find the same part somewhere else a bit cheaper. Take your time grasshoppah!
