I bet $25,000 that the modular efi race motor 323ci 5.3 would make a better street motor when detuned to lower boost for pump gas than a bbf with a blow threw carb and a single or twins would equally detuned for pump gas.

The bbf will be making more power as its almost twice as big, but the modular will return 15-25mpg depending city or highway. On a true 30-100 mile cruise, your be very hard pressed to get the bbf to show maybe 15mpg highway with a gear vendors overdrive. 5-10 if its just a 2-3 speed.

Bbf's are great for a race car, modulars are great for street and good for racing.

Ideally, 4v coyote heads on a 600ci motor would be incredible, I hope ford eventually makes atleast a boss 429 with 4v vvt-ti heads even just as a commemorative crate motor.

How cool would a restomod 70' boss 429 be with a commemorative 429ci efi vvt-ti na mill making 750hp+? With twins it could easily make 1500whp on 10psi.

No one use carbs anymore for BBs they use standalones. He wants to make a race car by what he's talking about so the drivability won't apply anymore, as the car probably won't be street legal anymore.

If he's just going to track race it, then a bb with a bigstuff 3 and twin 67's will be enough power to get it in the 6's but he'll need to backhalf and 25.2 spec the chassis.

I would leave well enough alone, a fun street car is more enjoyable to me than a fast race car.

Way off what I want to do I like the 281 I never thought 8.50's with a darn close to stock long block would be possible... I think if you spin it to 8-8500 port the heads do some cams and put a real 30psi to one you can have a decent little combo low 8's maybe 7's on a buget maybe some race gas... hoping this little teksid will take another 200hp knock on wood

Keep it a street car, maybe when the 4.6 lets up and needs a rebuild, get in the low 8's/ high 7's with a rebuild or even more uniquely, do a 5.4 or better still a built coyote with vvt-ti heads and twin 64/66's at 30psi.

All things said, 8.50's is crazy fast already so congrats as is

Definitely port heads, different cams/springs, along with a more solid 30PSI you should be low 8's. All the best cobra times I've seen with a modular engine had a teksid so I think you should be ok.

?? Has he already done all those things or are you telling him to go that direction? If the cars already that far, then shoot for 7's with chassis mods and some extra head/cam/boost.

Ya if its a street car I'd look for power in the heads/cams/boost departments. Adding lightness will ruin a usable car.

yes I like the stock dash and interior except I hated the stock seats and I'm not into the gutted lexan look

It's not the turbo kit that's the problem it's the motor. If you want to go faster get a big block ford.

:dw:


i would trust a factory built shortblock/longblock over any off the shelf motor based on the precision and amount of detail that goes into an engine assembled from the manufacturer.......that being said i'm making over 800 to the tires and on a stock longblock intake to oil pan, recently compression tested it and was basically perfect across the board. If it broke i'd buy another stock engine, already been through the mmr nightmares.

I gotta agree with this, the quality control done by ford is second to none and it just so happens Coletti and his engineers picked a bad ass set up for a stock motor!:rockon::beer:

Care to explain the MMR nightmare? I've been thinking about doing business with them in the future but hear nothing but bad things.

If I had to build a motor, it would either all be done by myself, or by one of the reman's from Tousley, and put on head studs.
