393 stroker in a 94 cobra

[greenstang1313]

This is my newest goal for my car. Just wanted to get some opinions and see what you guys thought....

I'd like to have a fully built 351windsor stroked to 393 with H/C/I and maybe a supercharger eventually. I know a guy with a '69 Mach1 with a 393 running 10's on nitrous. This setup wouldnt be happening for a couple of years but I have never heard of someone with a 393 stroker in a SN95 so I wanted to see if theres a reason for that.

Ive also tossed around the idea of a 408windsor but I've heard that they are extremely heavy motors and its not worth the power gain.

Any ideas/suggestions/comments are welcome.

Sounds awesome, but you will need some VERY good tires and a some major suspension upgardes to handle all that power. I'd do a serach on some info regarding a 351 swap to see what all is involved, but I do know you need either a taller hood or drop the engine lower in the bay.

huh?

low-5.0 has a 418
i have a 410
parchisi has a 408

that is just 3 on this forum that i can spit off the top of my head.

there are more over on corral

the hp gains are amazing, and the torque is killer

Id go with the more cubic inches cuz theres no replacement for displacement.

408 is no heavier than a 393. whoever said that the hp gains are not worth it is an idiot.

aluminum heads take 40 lbs off, that would offset most if not all the difference from the block

plus if you get an aftermarket k-member (aje for example), that takes off more weight and lets you drop the motor and also move it back, both of which help get it under the hood.

The 351/377/393/408/427 (I think there is also a 454, out there.) strokers are all 351w blocks with different bores and strokes. They all weigh the same and take up the same amount of space in the engine compartment. I would say that you should go with the largest displacement that your wallet will allow. Scat makes the crankshafts (408) in China for about $500. Rod's will cost you another $500. Pistons will be another $500. Oil pan/pickup tube, headers, and a truck distributor will add up to another $500. Block prep, heads, intakes, etc will all be the same as any 302 build. All that said, it is a VERY economical build for that type of displacement.

some blocks can be bored and stroked more then others, i know i saw somthing like that on fordracingparts website. But im curious if ur gonna go that route why not go all out...personally id like to have a 427, since ford made one way back in the day. not sure if its based on the same motor as the windsor but i think it would be cool to be able to say i have a 427 not to mention its more cubes then what most do

 

[reddy351]

It's not the same block. The old 427 was based on the 352/360/390/406 "FE" engine series. The 427 "sideoiler" was the pinnacle of that series and was/is a true badass. (A big block that can turn 7500rpm with no problem. Makes upwards of 650hp (n/a) from the factory! And weigh almost 1000lbs, fully dressed. ) The blocks are almost impossible to find and can cost easily into 5 figures for a disassembled, complete engine.)
The FE series was used in pickup trucks well into the 70's, but they are junk, compared to the 406/427. (Even the 390 P.I.)

A Windsor based 427 has the potential to make the same power, with the right combo of parts(including an aftermarket block). It would be awesome to have a 427 Mustang.

How hard is it to put in with the stock k member?

How hard is it to put in with the stock k member?

Depends on the headers. Mine went in real easy. Some headers will hit the k-member(so I hear).

 

[BlackVert]

i dont know, but i have read that one can get drop mounts and slot the mounting locations in the k-member to move the motor down and back.

there may also be clearance issues if you go with long tubes on a 351 with a stock k-member. i'm sure you are all too familiar with the syndrome, move one thing and then you get the dreaded ripple effect.

Hooker makes headers for the 94-95's with a 351 swap. Saw them in a Jeg's catalog not too log ago...

out of curiousity is there shorty headers what would work with the 351w swap? other then trying to find some off a 95cobra R

 

[parchisi]

Yes, I'm sportin' Hooker 94-95 351 swap 1 5/8" shorty headers right now. I think they're meant as a replacement for the '95 Cobra R headers.
