Well I don't know of any but I'm sure it has been done before. It sounds time consuming and expensive. Unless you are planning a full race car. Then it just sounds fun.

Re: 351 swap help

I'm not really trying to build a Supercar basically a daily driver with some get up n go it's not the first engine swap I have done but it is with this bodystyle I am not really concerned with the price the only reason why I don't buy a new one is because I like this bodystyle and all years prior but don't care for the newer style

Just bank on about twice whatever you think. That's usually how it works out. Good luck.

Re: 351 swap help

im doing a similar swap on a 97.

you will need......

k-member from a 3.8v6, 5.0 v8 or 4cyl. fox body or sn95 type body. or you can just purchase an aftermarket 302/351 k-member (94-95 v8).. whatever you budget can afford.

351 foxbody swap headers....

i think 99 was the switch year for "return" to "returnless" fuel line. so im pretty sure you will have to add a fuel return line.

im not sure if a mod motor mid pipe will hook up to your 351 headers. if it doesnt you can just use a fox body v8 or up to a 95 v8 mid pipe. your pre-existing muffler section should bolt up regardless.



personaly, if i was gonna go that far i would make it efi. it prety easy. but if you got the carb stuff already, why not use it. i think you'll be real happy with it.

i think i mentioned everything... so i hope this was helpful an gets you in the right direction.

Re: 351 swap help

no.. you will not need a new driveshaft. but you will need to purchase a 351/302 t-5 bellhousing and prolly a 351flywheel. i dont think 4.6 bellhousing is the same as 302/251 (but you should check on that).

Re: 351 swap help

The only reason I thought I would need a new driveshaft is because I have a t5 transmission and the yolk is 28 spline and the driveshaft yolk for a t45 is 31 I was wondering I'f the 94/95 mustang driveshaft would work with it I pulled a k member out of a 94 mustang and I think I'm going to stick to the carb setup should I just run a new fuel line ? I'm trying to leave alot of the wiring harness I'n the car that's already there so I don't have to rewire my top my windows steering column I go to pic up the engine tomorow I'm really hoping that my current powersteering pump will fit on the 351 block or else I will have to convert the brake system to a vacumn booster and just put a older style pump on it that will be easy my goal is to have something unique that would be fairly reliable but I think I can keep this project under 2 k ppl keep getting on me about resale value but idc because it has a salvage title so it's not worth anything anyway it's more sentimental value to me then anything I built it over the summer starting with a burnt up frame from a garage fire but

Is that flywheel the same as for a 302 6 bolt. I got a buddy selling a brand new billet piece. It's very nice

Re: 351 swap help

i didnt realize you had a t45 in there. i suppose you may have to get a driveshaft, a 3.8 driveshaft should work for you cause it may be easier to find at junk yard than a g.t. car.

do carb cars have a return line? i cant remember. if they do, you will need to run a return.

you can use your pre-existing fuel line to run the engine though. just tap the cars fuel line to the mechanical pump on the block. the mechanical pump will pull through the electric pump in the tank, so you dont have to mess with it. you can also use a low pressure electric too (they have "in tank" and "external in-line"), it's up to you.

when you pull the factory engine harness, start from the under the dash (passesnger side) and pull out from the firewall. only take out what's connected to the pcm harness. go slow...it you aren't sure, dont cut it! the cars' electrical accessories runs off of a seperate harness. you may wanna mark your wires for your gauges before taking out the old engine first. if possible, try to retrofit the gauge sending units (i.e. oil,water,etc.) from the old motor to the new one. chances are the older 351 sending units operate @ a different resistance than the 4.6 sending units... that way your gauges read accuratley after they are connected.

im pretty sure those two motors have two different power steering pump mounting bracket. use the older style 351 power steering pump and just hook into the cars lines.

im not sure why you would need to change brake systems... i think that car has hydro-boost right? i dont think you have to mess with it, but i could be wrong.

when doing this swap, try not to over think it. saleen did a s351 which featured a pushrod in 351 in a 2000 stang. they put 95 gt stang front accessories on the motor. there's another guy i seen that just took a whole motor and trans out of a 90 and put it in a '01. he hooked up everything efi all the way to a/c, and it was all stock parts...

my point is this.... it's gonna be easier than you think. you can use all 351 accessories.

the only real change to accessries i can think of is alternator. you need to use a 94-95 gt or 94-98 3.8v6 alternator. i think the old ford 2g alternators are 75amps... you will need the newer 3g 130amp alternator to run your car. you will have to do sum trimming with a grinder on the 351 alternator bracket but it will go... i spent $15 at the junk yard doin my 2g to 3g alternator swap... or you could spend $200-300 and get a 1 wire 130amp setup from p.a. or one of those other aftermarket companies

302/351 and 3.8v6 are the same bolt pattern..... but 4.6 is different and im not sure bout the flywheel balance.

Re: 351 swap help

I think the balance is on the crank like the non pi 4.6 the pi engine is balanced through the flywheel I know that because I blew the original engine I'n my car from stuck rings when my cousin drive it and never noticed the dark cloud of oil smoke and brought it home with the bottom end gone so I swapped it with a old thunderbird 4.6 and I had to use a flywheel off a older 4.6 out of a mustang their the same engine
