Fox Mustang: Next Purchase

586 posts in this topic

I'm unsure of my next big step on my Fox and would like a little input.

I'm looking at replacing the stock 302 with something a little more power.

As I'm looking at it now I have 3 options:

BOSS 302 crate engine, SysteMax intake --Not real crazy about the GT-40 heads it includes but one phone call gets it all

Built Dart 302/331/347 with TFS 170 or 190 heads, SysteMax intake, cam up in the air-- unsure of a builder

Spare Porno block, maybe 306, with TFS heads, SysteMax intake, cam up in the air-- unsure of a builder and the weak block but cheapest option

What are some thoughts?

Which Boss 302? Ford lists a lot of versions, even a couple race engine. :yum:

Is this thing going to have to pass emiss?

I'd definitely build it right the first time, so no weak-sauce stock block for me. :no:

Emissions is the big one, so I can't go wild on the cam nor do I want to. With heads and intake the stock cam can make 500hp with the blower without a whole lot of effort.

Looking at the X302E engine, of course the 363 short block did cross my mind.

Looks like a solid foundation. :yes:

From a durability viewpoint, it seems it would make a good emiss friendly 500hp supercharged daily driver. :up:

E303 Camshaft - Auto or Manual Transmission New BOSS 302 crate engines feature race quality components at entry level pricing.

Utiilizing all forged internals the X302E and X302B crate engines are an excellent value and a solid foundation for any performance combination including forced induction.

The best bang-for-the-buck in Ford small block crate engines!

302 cubic inches

340 hp

9.0:1 compression ratio (nominal)

Forged pistons

Forged steel connecting rods

BOSS 4-bolt main block M-6010-BOSS302

Hydraulic roller camshaft M-6250-E303 , .498" lift intake and exhaust, duration at .050" is 220 degrees intake and exhaust

Double roller timing chain set M-6268-A302

Forged steel crankshaft

Rear sump pan fits most Fox body cars

Ford Racing aluminum GT-40 "X" cylinder heads M-6049-X306 with 1.94" intake valves and 1.54" exhaust valves

Roller rocker arms

Built with all NEW Parts

Can be used in kit cars, street rods, Mustangs, Fox-bodied cars, and trucks

Depending on your application, a different timing cover, water pump, performance oil pan and pickup may be required. See installation notes INSTALLATION NOTES: See engine installation and tuning tips on page 95 Some or all of the following items may need to be changed from your original engine or modified for proper installation:

This engine has a rear sump oil pan and pickup, timing cover and reverse rotation water pump and EFI valve covers

A different performance oil pan and pickup may be required for your application. Call the Techline at (800) FORD788 for more information

The timing chain cover will work with most standard rotation water pumps.

Fuel pump eccentric M-6287-B302 installed, allows use of mechanical fuel pump

A reverse rotation water pump is installed on the engine. Other applications may require different water pumps and timing chain covers found on page 123.

The valve covers M-6582-BOSS302 should fit most non-EFI applications, optional valve covers (sold separately) are available on pages 128-130.

The damper assembly M-6316-C351 (counter weight removed) may require a spacer for pulley alignment, see page 142.

The flywheel included M-6375-D302B should work for most 157-tooth manual transmission applications. For other transmission applications use the proper neutral balance flywheel, see pages 171-172.

Firing order 1-3-7-2-6-5-4-8 (5.0L HO and 351W order)

I know this probably isn't your thing, but the 412hp 5.0 Coyote would be cool in your Fox, too. :yum:

Nearly the same price, too. http://www.fordracingparts.com/parts/pa ... ield=11829

I know there would be a bit more in the install and supporting parts, but it would be sweet.

Then again, you might could find a full swap in a j/y and get it for half that much. :w00t:

I do have the 4-cyl coupe that I haven't decided what to do with, but I need to finish my hatch first.

Unless the 5.0 pushrod gurus disagree (Disney?), I think that crate motor you selected would do it right. :yes:

I've said it before, but I think you should build a stock block, crank and rods shorblock. If it does crack the block most likely it wont' hurt anything. If it cracks, usually they just loose oil pressure and run like crap. It's not catastrophic. 600hp should be enough to break your t5, a set of stock axles and smoke a clutch. :D

I'll throw in my suggestion here from past experience.....

Matt Allen (66sprint6) and i done a Trick Flow top end kit (older version made for pedistal rockers) on a stock bore 5.0 and it made a HUGE difference in the way the car ran than previous with the stock top end. He did get it for next to nothing but its qorth doing for minimal cash.....just remember to upgrade the fuel pump.....don't ask how we know... :stare:

Yup, Pates right. I had VERY little money in the TW combo and altho she wasnt a Dyno queen she made up quite a bit at the track. She had alot more in her as did I as the driver but the shortblock was a dud lol. I have a nice budget stroker sitting on the stand and I often debate on whether or not I should scrap it and go back to playin with a stock block (or mexican) 302 with some spray.

I need a SCT ba2400 MAF so I can get this pulley on and get tuned. I got some stuff to sell first.

Aftermarket block should be the next purchase.

It is why I was looking at the crate engine, just not crazy about the GT40 heads.

I'm not getting an answer on Corral, but does anyone know what parts are required to swap a 4-cylinder front to 5-lug? I read you can use rotors off 83-94 Ranger with different bearings, but I haven't been able to find out what bearings are needed.
