302 Swap in 69 Mustang
 
I have a ’69 Mustang with an anemic 302 in it… what’s the best (largest) engine that will bolt up to a c-4 auto tranny? I’ve always been a GM guy… sorry for the stupid question.

vf,
a 460 bolts up to a C4....but...ya gotta beef up the C4 to live with all that torque.....
pretty easy to build a 460 to 500ft/lbs+

68' thru 70' (all the same unibody) Ford stuffed just about every different big block they made at that time into Mustangs....

here's what a SCJ 428 would look like in your bay (customer's car at the shop for restoration)

Ha, you read my mind... a 460 is what I had in mind... what do ya gotta do to the tranny?? Is there a kit or something??

You can buy one already set up to handle a lot of power or I guess a transmission shop could do the same thing. A 460 has a lot of power but will fit tight in your bay. The Mustang won't handle as well with all of that weight on the front end. A 351 Windsor can be stroked out for a lot of cubic inches and with all of the aftermarket parts it can be made into a great performer. It is also a lot lighter than the 460. Another route would be to stroke your 302 to a 347. They can also be built to have amazing power.

Thanks a lot... maybe I'll go the 351 route. Thanks again!!

vf,
you asked for "biggest". I answered 460....

but what is the hp/tq/et/etc goal your looking for....

"if" you just want to go really quick once and awhile....a $500 nos kit would do it on your 302

vfr172pilot 08-28-2007 10:15 AM

I've heard nos will damage you engine. Any thoughts?

red65mustang 08-28-2007 05:57 PM

vf,
any/all of the NOS suppliers/mfgrs web sites have a "info" page like this link example:

http://www.forcefedperformance.com/Services_NOS.asp

look up all the different kits mfgrs on summit or jegs....each site will have more or different additional info

vfr172pilot 08-28-2007 07:39 PM

As always, THANKS for the info!!

vr,
your welcome but to be honest....it would take me forever to type all that out with just 2 fingers!

food for thought:

Key to any fun street car is max TQ (not hp) to the tires at all normal driving rpms...

TQ=real "force"=push you back in the seat fun

very very generally cubes=max TQ (why a 460 will give you a neck ache)

stock 302 with a decent tune up is 300ft/lbs
300ft/lbs x 3.00 gears = 900 ft/lbs of twist force on the tires
300ft/lbs x 3.73 gears = 1,119 ft/lbs of force on the tires=Hg is higher=more TQ with less load and a pretty darn good increase for "wow" acceleration with very little gas pedal

$500 gear swap is the best bang for the buck on a 302...ain't got cubes change gears for the same tq at the tires...
stock 351W motor x 3.00=1050 ft/lbs at the tires approx
TQ cam on a 302=about 320ft/lbs
320x3.73=1193

The 429 was not used in a MUSTANG until the 1971 model year other than the 69/70 BOSS and those were specially modified to take them.

While a 460 will go, it will require apron work. The car will then be nose heavy and only fit for straight road driving (hot street).

(IMO)

A lightly modified 302/351W will give you much more roadability unless you are just looking for flat out performance.

you also ask wkat would bolt to the bell housing. that would be 302/351. to bolt up a 429/460, you have to change bell housings. they are avail, but pricey. best bet 351 windsor.

boss 429 1969/1970, rare, but they exist

guys,

I went back and changed my post to: just say: Ford "big block motors" (not 429)....cause about every motor Ford built was stuffed in them....

vf,
food for thought:
I'm not a big fan for starting with a 351W....250hp/340tq stock....
because it has the (small valves, TQ biased I/E) 302 heads on it....
to get performance above about 4500rpms....
you have to buy after market heads.....

"but"
the brand new totally complete (intake/dist/etc) crate motor is a heck of a buy ($2800?) and is definitely a fun "cruiser" motor just stock....
it is taller than a 302 in a Mustang so do check the air filter and carb and intake hood clearance before you buy

I do agree with putting in a big block does ruin the handling....

whoops, double post....(server hiccup?)
