460 in a 66.

A friend of mine has a 351c in his 65 and didn't have to shave the shack towers or modify anything. I'm currently installing a 408Clevor into my 66. Its a stroked 351w with 351C heads. This is major surgery. Shock towers shaves about 3" back. I made my own headers. I also lowed the engine 1" and moved it back 1/2". For the Mustang II suspension, its nice but not worth it for the little gains you get for that price. I've seen a 65 with MII kit installed that had a 289 in it. The engine compartment looked naked. There was so much space under there it just didn't look right. I'll take some pics next time I see it at the car shows.

Do you happen to have pictures of the 460 in a 65/66? I'd like to see how minor the surgery is. I know that fitting any real header on a 351W is major surgery so I can't believe a 460 is minor unless the fact that the exhaust ports point down further helps enough. Either way I'd like to see pictures. I've yet to see anyone do this but would love to see it.

theres a few problems associated with the 460. if you are able to fit it in, the 64,65,66 mustangs are not designed to handle that much motor.. besides the weight you will have major problems with both axle wrap and the frame twisting. its just not a wise choice, the biggest motor i would ever go with is a 390, usually not even that.. a built small block motor is all the motor you need in one of those mustangs

Wow, read the post right above yours.

Edit: major surgery I suppose is an opinion. The shock towers are pushed back a little, well, I guess about 3" at the base above the upper control arm. theres a lot of reinforcement into the front chassis too. I don't see anything wrong with putting a 460 in a 66 personally. Sure its hard on the frame, just reinforce it. I don't think I'd ever put a 460 into my 66. I'm just saying, it can be done. oh, gotta add, I do not know anything about that picture. I found it online and thought it interesting enough to save it. I don't know the owner or what he was thinking at the time.

Sorry, the picture didn't show up for me when I posted that. There is alot of modification done that's for sure. None the less I see now that it is possible.

Sorry, I didn't mean it that way.

I would like to do something to free up some space in my engine bay with out doing the mustang II conversion. Changing the plugs in my cleveland is near impossible.

In a 1968 Mustang with a 390 you had to jack up the motor to just to change the plugs.

The shock towers were cut and there is a kit somewhere that has weld in patches that you see there. My friend John Dinkle has a 351c in his 65 coupe and he cut back the center hump on the shock tower. If you open your hood and look at the shock tower you will know what I am talking about. I'm installing a 408Clevor in my 66 now, and if you think the 351c was tight. I cut my shock towers in a way that I could fold the flaps in and weld it back together, it looks very messy but I plan to weld some sheet metal over it to clean it up.
Not a big block but here's my test fit:

Sorry to take this a little off topic.
That is the 351w I blew up at the track now so dubbed the mock block, and my 351c heads. The heads I picked up were already prepped for a B302/Clevor application and machined for those exhaust port adapters seen in the pic. Those adapters make it even tighter when trying to change the plugs. I think without them I wouldn't needed to worry about plugs, but I have a header clearance issue too. I'm using 351c conversion headers to plumb the clevor, it did take some monster garaging to get everything to line up.
