Yes, I am very happy with it. I have about 2k miles on it. I'm looking to go FI with it to make it have a little better driveability (carb is a bit big and it's a little bit cold blooded to be honest).
What kind of gas mileage you getting , I noticed a 2 mpg drop when I changed over to a Holley from the stock Carter AVS .
The Air gap takes a while to warm up when it's under 40 degrees out , once warmed up it runs well . What FI unit you thinking of getting ? I've been thinking about FI as well , just not sure which to get .
In short trip city driving I'm getting between 12.5 and 13.5. I ran a longer trip to work and back on one of the tanks and it was about 14.5. I've had 3 different engines in the car and they all got about this mileage. This one is a lot more fun. I don't have the vacuum advance hooked up or anything. I'm thinking with better fuel control the MPG will go way up.
I'm looking to do full sequential spark and individual coils - so Megasquirt 3X or Megasquirt 3 pro, GM LSX coils, Edelbrock Super Victor EFI manifold, etc. It's probably going to cost about $3500 to do this (less after selling the intake, carb, etc) but I have full control and the best of everything for spark and fuel that you can install on an engine like this. The fuel system,some of the programming (autotune feature on Tunerstudio will get most of it fixed), and mounting the crank pickup wheel will really be the tough parts. The cam sensor is just a 92+ Magnum distributor so that's a drop in.
