i have a 1965 mustang and i just bought a 351c for it and just rebuild it for the car and was wondering if there were any tips that i could get on the swap i know i need different headers and motor mounts but i just dont know were to go to get them and if they even make them for such a swap i would perfer long tube headers if i can get them but would settle for shorties... and the last question would i have to get a different trans i have a c4 but have been told that i would have to get a c6 just want to clairify that one up and just how difficult the swap is in general and if there is any modifications that need to be done.i dont want to hack the body to shreds either i would like to stay with a stock look...well thank you for all your help and input on it.

First, I personally think the shorties would be better. You get a lot more versatility with them. I have them on my 65 289 and they are great to work with in that cramped, little engine bay. But that is just my own opinion.

I have also heard from some people that the long tube headers give issues like road scraping in bumpy/pot holed road areas, coming out of some driveway/parking lots, speed bumps, etc.

The 351C. I heard that it makes things really cramped in the engine bay. I have 'heard stories' of people having to beat on the shock towers a little bit to make the manifolds/headers fit. But that's just what I heard. But I have heard clevelands have great power potential.

I believe the Clevelands are suppose to be a little bigger than the Windsors.

ok this advice will definetly be considered for the future drop in of the motor and for the clevelands being bigger than the windsors i have heard the deck is bigger and have also heard that the cleveland and the modified block is the same...but im not to sure about that one..and thank you for the advice

[cindys_sn95]

it is a pretty easy swap. the mounts are the same, the c-4 will bolt up,(i may need a rebuild to hold up). and hooker and headman both make headers. p.s. the 351M block is not the same.

[Lizyness08]

ok thank you very much and one more question any websites or a contact number i could call to see the pricing and everything...and i was told that the cleveland and the modified blocks are the same is this true?

[cindys_sn95]

jegs and/or summit should have the headers. and NO they are not the same. mounts and transmission bolt pattern on the M are the same as 429/460. on the cleveland the are the same as 289/302/351W

[Lizyness08]

ok thats what i thought but local hot rod guy told me that it was well thank you for all of your advice and i will keep updates on how it goes.

[Lizyness08]

well there was a big mistake that was made on my part i made this post before i actually knew what the block was and come to find out it is a modified block so now im in a jam i have to start from ground zero and see if it will fit in and the heads and mounts i need for it i got the transmission for it but still gotta find everything else...it was a big mistake on my part so any advice this time will be taken and used if i can still do this kind of a motor swap..so once again i need the help from the guys at afm for there inputs and advice...thank you and all of its greatly appreciated

headers and motor mounts***

[2Manystangs]

no no no...I Cleveland or 351M will not "bolt up" into a 65 no matter the mounts, you will have to cut the shock towers to make it work, it's mistake to even put one in...351w/stroker or built 289 yes, but the boat anchor no...

Sorry to hear about your pain.

The 351m won't work, but the 351c would have worked for you. It is tight, but it does fit without shock tower work.

[Lizyness08]

well thank you all for the help ill probally just end up sellin the modified and gettin a windsor or just rebuilding the 289 for now..not sure what would be the best for my car tho my old high school auto shop teacher put a 351 in his 66 an its a mean stang but those motors are getting harder and harder to find and i dont have alot of money to spend seeing how i am a college student just tryin to get his classic back on the road...i am 20 now an got the car when i was 12 as a bare chassis an put the suspension and trans an rear end then motor in and had it painted and did the interior
and the past 2 years it sat due to valve terrain problems so i dont know need the advice....

[cindys_sn95]

The cleveland may fit but plan on keeping the engine crane for changing the sparkplugs..
