to SBF or BBF

Oh an factor in everything else - accessories like PS and alternator, are they going to fit on a coyote? motor mounts? Side pipes exist or do you have to go custom?

Personally, I'd look at MPI for sure, either on old school engine like FE or new Coyote / LS series. Especially since you admit you don't have skills/experience with the carbs and don't want to be bothered with them.

For instance, I built a 445 inch Windsor that made 660 hp here on the dyno, at around 7000 rpm.

I also built a 529 inch BBF that made 740 hp, but it did it at only 6000 rpm, and had 700 lb-ft of torque to boot.

It all depends on how rowdy you want it to be, what type of gas you want to run, and what you want it to look like.

The BDR and SPF cars both will accept pretty much any engine you want to throw in them.

Honestly I haven't looked under any of the hoods on these cars and thought wow that doesn't look good...unless it was just filthy. The 427 motor doesn't do anything for me that the coyote look doesn't. I'm way more concerned about the look of the car and it's cleanliness than popping the hood and wanting it to be original looking
*would run 93 octane only and I want the most bang for my dollar. Only thing I will say with my limited knowledge is that it can be as rowdy as it can be I just don't want a cam that stalls out or that you have to be on the interstate going 80mph to keep from surging

I am new here, but from engine perspective, the fuel injection stuff is more complicated to get setup, but most modern shops/companies are used to dealing with it by now. You need different fuel pump, lines, bung for o2 sensor, that sort of thing. But saying you can have older engine and make it MPInjection. I think they have to be base lined and setup with a data table to run on until they go into closed-loop mode (where fuel mix is determined by the o2 sensor and other sensors). That's about the extent of my knowledge and some of it maybe wrong, but you get the idea. I have seen a cobra that had a velocity stack sort of MPI setup and the guy was running it and it sounded incredible. Crisp, and monster powerful sound.

But a modern engine like a Coyote that was designed specifically for FI seems to me make more sense. Plus they are aluminum blocks and less weight on the nose of the car. MPG if that matters, would be higher I'd imagine.

Buddy has a car collection, and the carb cars - well they act like it. They dry out in week or less, and get hard to start. They gum up, especially on modern gas. They run crappy generally until warm. They can get vapor-lock in hot temps.

I know you would likely spend $$ more on a FI car than a carb car all things added in (fuel tank/pump, tuning, wiring, etc) but it would act like a modern car in terms of driveability. Seen some awesome C2 corvettes that have a modern chassis under them and all new gauges set in the original gauge cluster, etc. But cost on them is well north of six figures.

fuel injection would only find its way on my car if it was a coyote. 2 local cars here have different EFI systems on Roush's and they both are looking to go back to a simple carb. I am in no way saying FI can't be done correctly but It doesn't appeal to me for the cost.....and my elevation and driving conditions wouldn't call for it

I think the coyote package has been figured out to a degree with certain vendors. I'm not carb shy I've been told you just get someone to set it correctly and then leave it alone and you will be okay as long as you don't let it sit up and obviously there will be some maintenance at some point

Cams don't get that big...

The cam in that 445W that made 660 hp @ 7000 allows the customer to idle around his neighborhood, over speedbumps, etc.

And yes, you are correct, once the carb is tuned, you should be good to go.

The good thing about the larger big blocks is that you have the horsepower and the streetability both. They will cruise, run on pump gas, etc., and you can give them as much throttle as you see fit. Pretty easy to get 700 hp out of them and cruise around like it's nothing.
