I would like to know if I can fit a 400 or a 460 into a 70 maverick with out having to cut the shock towers and if there is someone who makes engine mounts or will I need to fabericate my own
Niether one will fit without removing the towers. A 351w is pretty tight even with notched towers, and the 400 and 460 are a few inches wider and taller. A mustang II front end would be in order for that swap to happen, or at least make it work correctly. You'd have to fabricate a LOT of things, motor mounts, radiator mounting, trans crossmember, the list just keeps going and going. If you went with a 460, it'd be a pretty neat swap as those overgrown engined have great potential. Don't knock the 400 though, even they can be built to over 700 HP (yes, I've seen one with iron 4v cleveland heads!) Good luck
I put the shortblock of a 460 in once for giggles and that is all I could get in . Same thing for a 428 FE block
yes, I did the same thing. The 460 block was wide enough that the heads would not even go on the block without contacting the shock towers.
If you don't want to do any tower cutting forget about it. You will get into more work than you ever wanted, before the job is done. There are problems all over the place from front suspension, steering, exhaust, cooling. The big block engine weighs a ton to boot. Then there is a need for better trans and rear. If you really want to do it, it can be done but time and $$$$$$$$$ are needed as well a a lot of learning. It's called re-engineering. The factory take years to work out a setup plus all the money and people to do the work.
Less filling and runs GREAT Or you could stroke to 408, with 6.20 rods and a nice Eagle crank and pistons you could have over 400 cubes. The reason I said Eagle instead of SCAT or Ford Motorsports (one and the same) is because they knife edge the counter weights a little to much and make the crank to light, so you have to have heavy metal installed when you get the assm balanced and damn that's expensive. Some say that going to a 427 stroker puts to much side load on the block and that it's not the type of horses and torque that you want in a motor that's made for speed, more for pulling. It is about as big as you can go without doing the mustang II thing. I hope this helps, and as always this is just my 2 cents. Terry Gates AKA Bossmav
Re: Less filling and runs GREAT The 393 I built used a Scat cast crank w/SRP lightweight 302 pistons. Needed only one small "hole" drilled in the front and rear counterweights for balancing. I guess they design them for lighter bobweights, therefore if you're using TRW or similar pistons (a.k.a heavy) it would probably need some mallory metal. The 393 worked well, but stock rods don't like 7200 RPM. The 408's are good runners....but require a lot of cylinder head to make them perform to their potential. If I had to do it all over agian, I'd build a SVO 4.125 bore 351w 9.2 deck block with Yates C3 NASCAR takeoff heads. But for now, I'll stick with the little 351w. Good luck
Time and learning YES but Money is not that much as long as you do it your self and take your time........just my 2 cents.......I bet I'll spend more $$$$$$$$ on my wife's grabber than I will have ever spent on my big block car........
Re: Re: Less filling and runs GREAT Mavman is right, the 408's do need to breath. Put on a set of out of the box victor jr heads and "boom" your breathing. Now do a little port job and you really got some O2. Have a good weekend everyone! Bossmav
ok guys, whats up with this? owner says it's a 460, in a maverick. this car was up for sale once on ebay and was recently listed in auto trader. only thing i figure is mav shock towers changed out for a 70s mustang and engine mounted high. anyone in florida know this car?
Looks like way too much clearance between the shock towers to be a 460. There's less clearance with a stock 302! [No shock tower to firewall supports, too! I bet the car is twisted.]
yes it is a 460 on that car they shaved the shock towers by the inner fenderwells and re atached them........but they are also running coilover shocks on the front to give them the room......mine is still in the ruff stages but here is how mine looks......keep in mind that I used a MII setup......
