Hemitronix vs Megasquirt $

To try and provide a fair assessment - its really the lack of a good intake manifold that stops it being a completely acceptable solution.

Sure , you wont get the same economy, ease of starting or mid range torque that EFI can produce - but for an old A body with its light chassis and less reliance on a controlled engine management system to look after air con, shift points, cooling, timing and fuel demands , I dont think the losses in torque or economy are deal breakers.

FWIW I averaged 21 mpg on the hwy - and that was with a 3800 converter and 3.91 gears...a 27" tyre and doing 3100 rpm at 65mph!!

I certainly would NEVER advocate using carbs on a heavy LX platform however - the EMS provides huge bonuses in this environment.

Back to A bodies.....If you're chasing 10ths, a computer controlled EFI will ultimately deliver more benefits in an A body.....but I believe the type of vehicle determines how much gain you will see. Of the car spends most if its time at WOT..EFI may even limit the outcome.

Like I say..I was staggered how much better my car performed with the correct choice of carbs ..and theres even more to screw out of it yet.

.....and I think the Drag Pack combos prove that ultimately, the issue of carbs vs EFI is a bit of a non-event for a street/strip car.

- BUT , hood clearance is the one major deal breaker...be it a Modman with spacers, Eddie dual plane dual quad or Drag Pak ....stock hoods are not really an option even with drop base cleaners.
