440 going with efi?

Depends man, what do you want? In detail.

Of course a TBI unit will be easier to not get smelly. But more costly. You can tune a carb REAL well with a stand alone wideband like I do.

Is this going to be a race car? Do you want the BEST TUNE EVAR? Or do you mostly street, visiting the track a couple times a year? How much do you plan on using the car?

I`ve got a fast 2.0 on my 505" 440. not completely ready to drive yet, so no real help here. so far, not sorry I did it !
