351 cid into a 65 mustang

[midinite]

Anyone here know what is needed to slot in a 351 engine into a first gen mustang? Will there be need for some suspension work to accomodate the bigger engine? What other things should one know?

want to create a sleeper.

What Carroll Shelby did in his GT500 was to shave off or takeout the shock towers in the engine bay. Of course, he shoehorned a big block in the fastback.

Baka kasya yung 351W sa engine bay. 351 Windsor is also a small block Ford engine. If your engine is a 351 Cleveland, baka hindi nga magkakasya. In this case, you'll have to shave-off a good portion of your shock towers.

PM Turbo coz he was able to shoehorn a Ford 460 big block in a '67/'68 fast back.

remind me again what the stock lump in the '65 was? was it a 289?

regardless, i believe Ford sells 'crate motors' of various displacements that are meant to be more or less plug-and-play with the stock mounts and linkages. not sure if you can source one over there.

Midnite, You better just put in that 351 on your stang, beef up your springs, and other mods if you want a ghost of a chance of catching up with my ride's 390FE. Hehe.

Which 351 do you have, a Windsor or Cleveland?

that is a good question. the block casting numbers make it all the more confusing since it can either be a 351W, 351C or 351M/400. Need to check where the radiator hose goes, how many bolts on the valve covers etc.

to answer the question about what the original engine was mustangs of that period came with the 289 which was discontinued with the emergence of the 302 which was basically a re-bored 289.

shelby's of the time - the gt350 used the k-code 289 while the gt500 the 428...

there were around 6 mustang shelby convertibles in 66 but they did not use the 351...

shock towers can be replaced with mustang II semi-coil over suspension...

how about a roll cage?

now who can help identify what the 351 I got is? the casting number says - D4AE...

Hamon ba yan Hotrox? Have seen a 57 chevy with a 283 beat a 69 camaro with a 396 and a mopar 440...during my dad's time...secret isnt the size of the engine...i'll tell you more about how my dad and tito did it when we go to bulacan

sourcing isnt that problem...got ways to bring cars in...my friend just brought in a Dino from NY...so engine shouldnt be an issue..its just what mods will need to be done to slot one in...even if it were a crate...would that mean getting a kit to convert shock towers to coil overs? etc.

never done it myself, so i'm not the most informed source. i did help my friend install a crate in his camaro and afaik whatever mods need to be done are sold as part of the package. i don't remember if we needed to mod any towers or mounts...

what year camaro? what size engine? that would possibly dictate what would be needed as far as making room or not making room...

you cant recall if you touched the shock towers?...if you didnt even touch em then could it be remotely possible that the engine was not too big? so it fit right it.

The Cleveland looks very different from the Windsor. The Windsor is a tall block 289/302 variety.

If you want something different. Get a 302 block and put 351C 4V heads. An instant 302 BOSS. Add some solid cam and lifter set, roller rockers, dome pistons to get atleast 10:1 compression to avoid knocking.

Better use the BOSS combination.

D4AE, 351W veriety.

Meron akong Mallory UNILITE para dyan!

It seems you have a windsor as Turbo rightly pointed out. That engine can fit your engine bay without taking out the shock towers.

You can buy 351-W engine mounts from mustangs plus or mustangs unlimited for a direct fit. I believe both on-line shops sell the Prothane brand.

Btw, you are right in saying that a 351W can beat a 390FE. Firstly, the 351W affords the car better balance being lighter than the 390FE engine. Secondly, you can tweak the 351W for higher revs by replacing the stock carb into a Holley double pumper 4-barrel type and getting a high-riser intake manifold. Getting aftermarket cylinder heads (Trick Flow) would greatly help in stumping the 390FE.

Good Luck in your project!!!

By the way, Chevy has no shock towers. And Camaro engine bay can accomodate a Big block with just a Big Block mount change. But you have to replace the springs with a stiffer set.

As for using Mustang II suspension, it is a very technical job that needs careful measurement and alignment.

Stay with the 302, and set it up with K-code specs, just like what WOODFIRE did. Solid cam and lifter, roller rockers, dual plane intake, Mallory Unilite.

If you are going the solid cam way, be adviced that though solid cams offer excelent performance, periodic adjustment of valve clearance is needed.

It is your call.

By the way HOTROX, I have a set of GT heads(14 hole-exhaust bolt) for your 390 FE. These are hi compression heads.
