Here's another vote for q-jet.  Assuming they're re-built properly with a good kit and all the right stuff done to 'em  (i.e. new bushings for the primary throttle shaft if necessary) you can't beat 'em for street-ability.  And they're not too bad on mileage since the giant secondaries only kick in when you get into it a bit.  (That is if you can avoid getting into it too often.  Tongue)

Can't remember, do the regular old E-brock performers (dual plane) fit under stock hoods with stock air cleaners?  I think it's close if remember correctly.  Performer is probably easier to find than the L-82 aluminum......

    Talk to SARGE about F.I.  He's the pro. I love my Q-jet. It IS done right, but cost me some pennies, LOTS. Works well!  I'm getting about 17-18 MPG.

Q-jets are my favorite.  I tried a Holley Q-jet replacement back in 1980 when they hit the market....I cannot remember it's name?  Anyway, gas mileage was off big time and it did not have the same power under wide open throttle.

Here is a new FI company about to debut.  I think their website goes public soon.  Sounds a lot cheaper than the current FI conversion units.

Did you just go with the $995 throttle body, or did you also go with the $500 sump pump (or whatever it's called)?
