hello again everyone! i have been considering building up a motor then dropping it in my car after some nice work to it. it is a lot easier then workin on the motor that is already in the car. Since I have a 5.0, and i already have full exhaust, fully induction, and im sure i will need a chip soon as i am figuring out in a different post, i guess i shoudl build up another 5.0 and then use the parts that i currently have. well, my friend has a 98 gt (4.6) that he is going to swap a cobra motor into. that motor has 63k on it right now, and he will be takin it out in like february. he said he would sell me the motor for 1500 (no tranny, and i dunno about the computer and stuff). so i was wondering what some peoples opinions were regarding maybe building up the 4.6 since its SOHC vs OHV. but a 5.0 i already have a bunch of parts for and such...so i dunno ... what are some peoples opinions?

Would be lots cheaper to build a new 5.0, the 4.6 swap requires lots of things, EEC, wiring harness, gauge cluster change...big list.

[jruppert]

Personally I would stick with the 5.0. There are tons more performance parts for the 5.0 and the cost shouldnt even be debated. You will have to put a lot more into a 4.6 to make it as powerful as a well built 5.0. You could always add a blower to the 4.6 but still... I think you will find more people sayin to stay with the 5.0

or you could just do like me make it a winter project and drop in a 351w uses all the stock things except for an oilpan and headers and a few other things but cost isnt bad and you wont have to worry about the camoros and vettes in the world plus reliability and streetability is still there

[YoshiBluedevil]

could i build a 351 and just drop it right in? cause i thought i read somewhere that it was a tight fit and you had to move crap around and drop some stuff out. a 351 would be mighty nice tho, especially after a stroker to a 406, or 408 or whatever it is!

[jruppert]

You will need a different hood. Different oil pan, distributor, headers, lower intake, maybe a different timing cover and water pump, probably need it chipped, and you will need a reto-fit cam unless your going a newer roller cam block.

[dirtyo2000]

well you can retain the stock hood i did. i have a 94 stang with a 393. the oil pan and distributor i agree with and the oilpan. you will need a new intake lower for the winsdor but your top plenium will work. headers will be need unless you already have shorty headers they will bolt back up with no problem just have to have a muffler shop add to inches to your h pipe to fit back up. the 94 timing cover and all accessories all bolt right back up. the only change is a serptine belt if i recall about 2 inches longer have to check mine to be exact on the length. no room is need the wires to the alt and a few other places will be a little tight by that i mean they wont have the little curves and all but everything fits and works out nicely. if you just want to drop a winsdor in and do small mods to it later get an oilpan and dist and lower plenum for the intake and your pretty much there. granted in the end you will be buying things like injectors and throttle bodies to get the most out of your combo but it can be dropped in and driven for under 750 is what a friend of mine spent. the car is back on the street and driving everyday. runs 13.000000s all day and hes building a stroker for the car. now 13s arent all that great but he is using a stock winsdor with nothing but his 5.0 stock heads and cam that cam with the car. the whole top end is totally stock down to the 19lb injectors and stock air filter set up. its fun in the first few gears but the t-5 is starting to give out. he has almost everything to upgrade the fuel system and air but hes saving it for the stroker.

[YoshiBluedevil]

ok so basically, if i buy a block, i can use all stock 5.0 parts except the oil pan, distributor, belt, and lower plenum. then i will need to add a few inches to my o/r xpipe. so look on ebay or AFM classifieds for a 351 block, and im good to go?

[dirtyo2000]

thats it now remember that you will need to buy all kinds of nick nacks for maximum power but to get on the road what you listed is all that you need. and your riding. you'll be pleased but the potential is unlimited. any questions that you may have feel free to ask im working on one right now for a friend and all that we have done is taken one out of a van put on the e7 heads and a roller cam and oil pan. used the dist that came with it because its a efi so well start it and drive it while he saves for some decent heads and intake plus injectors to really make things move. trust me you will love it

[jruppert]

please be advised that if you plan on going a roller cam you need a new enough block. Just because you go with a 351 from mid 80's wont make it a roller. You will need to get something new enough. If you go older then you need a retrofit cam. Also, you can go with a 351 from a crown vic and use the oil pan and pickup from that. Also, the heads on a 351 bolt on differently then a 302.

[dirtyo2000]

r u sure about the heads because all the heads that i have seen for small block ford are interchangeable from the 289 to the 351 only difference being the intake. granted the older heads dont thave the air tube between them and the after markets dont either but all the heads that work on a 302 will fit on a 351. has for the cam its has simple has taking the spider off the 302 and putting it on the 351 by drilling the two holes in the lifter valley area thats what i did. my motor came out of a 78 pick up and the heads are now on my little ranger with a 302. everything went right in the 94 but i have a lot of money tied up in it because of ed curtis and all the stuff that i had to buy. basically all i used was the block because the project grew to fast. had to buy a stroker crank, then eagle rods were a must, custom pistons from probe, cam from comp with ed curtis numbers, afr 205's knocked a big dent in the bank account, edelbrock victor intake for the 5.7, 1.6 comp rockers+the expensive ones lol, then i ran into problems with my hood because i changed valve covers wich meant that i had to get a spacer for the intake to clear them and that put the intake into the hood. i could have taken off the insulation and gotten by but no room for a strut brace so i wanted the cervini anyway. now what really killed me is that i had to buy every performance item twice. my maf was a 65 and i had to buy a 80mm, my throttle body was a 65 i had to buy a 77, car had 24lb injectors now it has 30's. had a mallory dist but now has a msd billet and 6al. none of the parts that i had would work becuase of the stroker. i finally got it running decent last month and im taking it to philly next week for a custom chip and want to know whats at the rear wheels. the tranny is acting a little funny but im saving for a new one. car is fun to drive though. once the chip is done and all the bugs are out ill post you some dyno numbers. plus i have a 150 shot but wont touch it till the motor is running right on the dyno then ill do a pull just to see what happens. everything i did was because i wanted to not because i had to. like i said its easier than you think but the quest for speed can be satisified with the winsdor. i had a stock one with all the before parts off my 302 and it ran great. i could knock off a stout 331 stroker with no problem and camora and trans am were not that much of a problem. and i only had a stock windsor with stock 302 heads but alot of dumb dumb stuff with a combo that wasnt worth talking about. now im trying to get the car to run low 11's to high 10's on the bottle in street trim fully loaded with the ac on and music jumping down the track

[jruppert]

The heads are the same. From what I understand its the bolt holes are larger on the 351. Also, you mention that you needed a 77mm throttle? I have never heard of such a size. 75 is the largest you can go on 94-95. Another thing.. I honestly dont know how you could have stuffed a 351 in there without hood clearance problems. Ive heard that if you change the motor mounts it is possible to clear hood but your oil pan is inches from the ground. The hood is already darn close with the 5.0 and an edelbrock intake. Plus your adding a spacer to your intake. Just doesnt sound right but I may be off. I just know that I have read numerous articles and have talked to numerous people about 94-95 351 swaps and they all say you need a taller hood. As for the cam, I am not sure what you needed to do with that. I havent messed with the different style of cam between the roller 302 and an old non roller 351.

[dirtyo2000]

just stating what i have done. now when i had just the 351w it went right in with the stock hood just had to remover a little insulation at the top of the plenium where it was at the middle part where it rounded up. all else was good has for the pan i have no clearance problems and it sat just like the stock one did. i changed the hood because i like the look of the cervini. but its the same one that comes on the 95r with the 351. i have made alot of changes. now i have changed to a tubular k member but retain the same motor mounts wich are just an aftermarket polyurethane kit that comes with the trans mount. i even run a 1inch spacer with the edelbrock victor. yes one inch but it contacts the hood ever so slightly so i cut a little grove under the bottom of the hood and you really cant tell. i have yet to find a brace for it yet though and if i do find one ill post who makes it. hopefully next week i can get to the dyno and see what a 396 does and if this combo is worth the time and money that was spent

[dirtyo2000]

oh now i run a 7 qt pan with the k member and still have lots of ground clearance but the headers that i brought from kooks hang very low to the ground so that seems that it might be a problem and a dead give away if you look up under the car that is what you see hanging down, but looks sort of like a real pro stocker if you lay on the ground on your side and look from the front to the back lol
