  1. 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
  2. If your total budget is $2,000, a hyd roller will not be cost effective enough, although supeior in performance. A gear change/or transmission change is a must. So, realistically, your budget is main limiting factor. Rear gear, set up, gaskets, and fluid will run at least $500. 3:73 is too low for a non overdrive street driven 455 that sees 70 mph speeds for long distances. We use 3:55 with a 700R4 overdrive transmission. With no overdrive, the highest I would go is 3.08-3.23 if you do a lot of highway driving, or maybe 3.42-3.55 around town. Keep in mind, Pontiac ran 3.08 rear gears in their
  3. Installed front global west s-41 500lb rated coil springs on the 69 fb. WOW, what a improvement!
  4. Our two 1969 400 Firebird convertibles. One auto, the other OE muncie 4 speed. Both with orginal AC.
  5. I might add, I found my vapor lock issue was the fuel heating in the mechanical fuel pump prior to the EFI install. Everything else i tried did not correct the issue, the EFI did. Gasoline at vacume, being sucked in by the mechanical pump way up front on the engine, can cause the fuel to boil at less than 90F. Vapor doesn't pump thru a mechanical pump.. Boiling gasoline at 60 psi has to be near 300F. This why new cars don't vapor lock, since they all have intank pumps and a 6" or less suction line, the rest is pressurized fuel line.
  6. I did clean up the wires some, wrapped then in flexable conduit. I'm a fan of things looking stock. I ran the power wire (Ron Francis 10 Gauge relay kit FP36) inside the passenger fender, into the car where the radio antenna enters, thru the cars wiring channel inside the floor, to the trunk. Here I installed the Ron Francis crash relay that disconnects power to the pump if the car is impacted. The holley system shuts the pump down if the engine isn't spinning. This all hooked up to the battery and is essentially invisible, as its under the fender, or routed thru the car. I do not believe in
  7. I needed 60 lbs of fuel pressure at all times with the Sniper. Its nearly impossible to find a external location to mount a fuel pump lower than the tank as suggested, plus I did not want to hear it. So. I ordered from Butler Tanks tan-tm32bn-t fuel tank with internal 400 lph pump as they recommend. Installation was easy, bolt in. You cannot see or hear the pump, and it works grear. No more vapor lock, no fuel smell in the garage, and cold starts like a new car every time. By installing the regulator at the tank, i didn't have to install but a 6 inch return line, and reused the factory 3/8 f
  8. Petronix is great when new. However, they fail often. When you run a hei you can get any part anywhere for it. When your petronix module frys, and they all do, you are stuck until summit or jegs can overnight you one. There is no performance advantage, the hei is superior in every way. Research it. Pontiac knew what they were doing. Larger cap, less crossfire. More amps to the plugs = wider gap= more power.
  9. A pontiac torker 1 is very similar to what you are describing. They were terrible street manifolds, performance wise. They looked good...
  10. my 900 cfm holley sniper xfi on our 469 is fantastic! With a few manifold mods, bolts on and run better than ever.
  11. of course it will, if the engine was assembled properly. I regularly ran a 200 kit on a 400 with stock rods and crank. Don't run it lean, meaning you better design and ensure an adequate fuel supply or it will melt your pistons like butter in a volcano.
  12. Butler uses the BOP seal. Use the 2 piece BOP seal. BOP themselves admit they have better luck with them than the 1 piece seal they make.
  13. doubt it fixed it. My flow cooler water pump made mine run hotter. My guess is a leak or you need a radiator.
  14. I can't tell if you are discussing pontiac engines or chevy engines. Regardless cubic inches matter. More is always better unless you are competing for mpg. A 455 will make more power and torque everywhere over a 400 cu in moter in a street car with similar equipment. And it will do better with a larger cam as far as idle and build power at a lower rpm, great for street cars. If you can buy an aftermarket block, stretch it to 600 cu in. It will trounce the 455 engine. Pontiac went from 326 to 389 to 400 to 455 for a reason. Torque.
