  1. I would recheck it. Its pretty common for the old rubber ring that goes on the filter to get stuck in the transmission and not be noticed, and then when the new is applied you have 2. For the brief time it takes to look, I would. Transmission rebuilds are not cheap.
  2. The line from carb to the pump is pressurized with gasoline. If it leaks, it can spray fuel onto your starter, alternator, plug wire, etc and burn you and your car to the ground. Every car I have ever seen from the factory has metal lines from the carb to pump. If the suction line leaks to the tank, it just quits pumping fuel. So, Frosty is giving some very bad advice based on others that have done it wrong many times. If the line never leaks, it might be ok. Even the NHRA limits the amount of rubber fuel line a car can have and race. This includes steel braided lines. This is for fire safety
  3. I've never seen one, but I have heard they exist. My bet would be less than 20 cars. It was an optional gear, so very few cars would need it. 355 was pretty common. Lower pretty rare on a stock firebird.
  4. Good luck! With the vapor lock issues we had, we didn't have a choice. While we are very happy with the Sniper, had we not had carb / vapor locking issues we would still be running a carb. As they add more alcohol each year to the gas, it gets more difficult to keep from boiling fuel in the lines, especially with increased hp which generates more heat.
  5. Running the single gas line to the front really simplified the installation. With the pump in the tank, the regulator returns everything over 60psi directly back to the tank. Pressure line to the front covered in tape.
  6. Wiring the Sniper was easy. The hardest part is removing all the wires you don't need, like nitrous, electric fan. Etc. You first take the car and have the exhaust bung placed in an exhaust pipe. Wires to hook up: power, ground, temp sender, O2 sensor, fuel pump wire to pump. To tune. tell the system the engine size and desired idle and start it. If self tunes. I think driving it around it tuned itself 80% in about 30 minutes. The Xflow Sniper uses a external fuel regulator, I set at 60psi. I bought a replacement battery that was the same size but had top and side post. I hooked th
  7. Regarding the tripower. Thier advantage is they look cool. A single 4 barrel exceeded there performance when the rodchester was born. The fuel injection is even better.
  8. FITECH makes a very cool 6 pack that is fuel injected. I have not personally used one but they look trick and have fuel injection! Check out https://fitechefi.com/product/go-efi-tri-power-600hp-system/
  9. Sure. The picture is of the same Pontiac iron spread bore intake manifold. The Holley Sniper X-flow has duel bolt holes to allow it to bolt to either a square bore manifold or a spread bore manifold. The issue with a Pontiac factory intake manifold is as shown in the photo, the restriction would have been huge if it had not been modified. To resolve the issue, we took a sawsall and grinder and opened up the manifold to the point that the Sniper would see no restriction. This resulted in huge power increases and no need to run any power robbing spacers. Sniper does make a 650cfm spread bo
  10. It all depends on the clearance you have at the valves. All Pontiacs have around .420 lift and most have non adjustable valve trains except on RA2 & 4 & 455SD engines. While they will physically fit on the engine rocker stud, Pontiac did a few things to ensure their 400 RA4 engines didnt blow up with 1.6 rockers. The push rod holes typically need to be enlarged to ensure the pushrod doesn't contact the head. And adjustable rocker studs are will be necessary so you can lash the valves. The factory valve springs will bind if not replaced, and the taller springs need their location milled
  11. The Holley X-flow 900 CFM works extremely well of a 468 Pontiac with a hyd roller cam. We made 500hp and over 550 ft lbs and have perfect cold starts, great fuel handling and better mileage than a factory carb. We modified the stock iron intake to accept the X-flow, bolts right up with no spacer required. Factory air cleaner fits, no hood interference and much more HP than a RPM+ or Torker manifold.
  12. We have 2 69 Fb's, one with a 4 speed muncie, one with a 700R4 overdrive with a tight 2200 stall convertor.. I love driving the Muncie equipped 4 speed, shifting the gears, selecting when I want to change the rpm level, and such. My wife hates the manual car, and loves her car with the 700R4. Her car will white smoke the tires for long ways, has crisp shifts, and at 70 mph is turning about 2000rpm. Both cars have 3.55 rear end gears. With her 700r4 she has the equivalent of a 4.20 rear end gear in 1st gear, and a 2.56 rear gear equivalent in 4th. Best of both worlds. The cars have differ
