MPFI or 8.1?

[PsRumors]

'84 Burb with a rebuilt 454 carbed. For about the same money I can either put a used 8.1 in or put a MPFI on the 454. I know the 454 is good the 8.1 runs and sounds fine, has 70k miles on it, '02 model.

If I go 8.1 I would be able to sell the 454 and recoupe most if not all my money. 8.1 w/ harness computer etc is $1900. Also, I'd be able to sell my 4l80e controller to recoupe even more money.

What does everyone think? A MPFI 454 would be the ****, but so would a 8.1.

With gas prices on the rise go with the 454 haha but honestly I don't think you could go wrong between the two...

Any idea what kind of numbers you'd be looking at?

Either one would be cool, and milage about the same, maybe a little better with the 8.1... and it's bigger The 8.1's generally do burn oil though.

Does the 8.1 computer control it and the tranny, or just the motor? I didn't think the 8.1 was available with the 4l80e, just the 5speed auto or the 6speed stick.

I thought the 8.1 had the 4l80 behind it....if not then I would need to keep my controller.

Avery, you asked about numbers....pricing? would be about $2000, hp? I have not idea on the 454...basiclly stock but it pulls the burb around very easy...the 8.1 has like 340 and 440...something like that stock

I'm pretty sure they had the Allison behind it
