  1. My first outing with my 72 this year wasn't as successful as I had hoped.My best run was 12.33 @110 mph lifting at about 1000'.I was launching very soft 60' were around 2 seconds.The 3.50 gear isn't a terrible choice if you are gonna go the 460 route.My car doesn't have any problem pulling a 3.50 gear. Keep in mind a stockish 460 might not run as good as a stockish 429. Most 460s were smog Era and most 429s were pre smog as a rule of thumb. What heads do you run?
  2. Weight is a big deal but the 429 can be trimmed down to be in the neighborhood of an all iron Cleveland.
  3. If you use FPA headers for the 429 you can put them on before you stab the engine.
  4. A couple weeks ago would be the last time the turn signals were used.Turn signals are working fine.Everything worked fine before I changed booster.
  5. Yes they spacers and bushing are installed correctly.It doesn't seem to me like it moves enough to make the switch break contact though.
  6. I don't believe it's a wiring issue.I have my test light directly on the spade of the output.When it will sporadically light when pedal is pressed it will light brake lights.
  7. After changing boosters I put the brake light switch back on the pedal.No brake lights.Went and got a new switch,still didn't work it .Finally got it to work ,came back an hour later no brake lights again.Has power coming in but power out when pedal is pressed is very sporadic .What can be causing this?
  8. The new booster is holding and it's working. I got another new MC with the booster. I talked to tech at GPS,he said they adjust the pushrod correctly and have never had an issue there. There's some free play . I really don't think it's a bad mc.This is the 3rd one I've had on the car 2 of them were new. GPS brakes gave me some tests to perform I just haven't had time to do them yet. Just a fyi.I talked to GPS about the upgraded 4 piston front calipers.He said they do work maybe slightly better but not a night and day difference not worth the money for the very little you might gain.
  9. Yes the Summit pump made by CVR is big and noisy.
  10. Well got the new booster from GPS on Saturday.Got everything back together.Bench bled MC.Bled the system again,Rear drums won't gravity bleed,but they will bleed with the two man method.Front brakes will gravity bleed.Seems like rear brakes are working pretty good and front disks not so much.They are working slightly better than before.I tried with the vacuum pump off and on,doesn't seem to be any difference.Pedal is still weak.Back drums are adjusted correctly if anything they are out too far.
  11. I was wondering if the bigger pad contact area would make much difference.I understand line pressure would be the same.Im considering it since I have to go thru a complete bleed out again.
  12. Does anyone have any experience/ thoughts on the SSBC caliper upgrade?
  13. Gps brakes said the new one was slightly thinner than oem so it shouldn't be an issue.
  14. I'm ordering one from GPS.Yes it's due to the thickness.The studs will come out of the holes but not alot.Had to tweak the brake pedal rod down pretty good and remove valve cover to get it out and it was still very tight.I hope I don't have to pull engine to get the new one in.
  15. Thanks for the offer on the pressure gauges Jeff but I may have found the issue,at least a major part of it.I checked my booster last fall and it was ok.Ran a check on it again last night,it won't hold a thing,0".Tried pumping it up with my hand vacuum pump couldn't get squat.Hooked up the electric pump which is putting out 20" Tee's a vacuum gauge in between the pump and the booster.Didnt build anything at all 0".Pump just ran and never shut off.Pump is functioning correctly shuts off at 20" kicks on at 15".Took the old booster out,which is a pita with a big block.It was in very rough looking shape,very crusty on the back side.I sure hope I can get the new one in without hosing it up.
  16. If something was wrong with the proportioning valve could that cause a lack of pressure at the calipers/cylinders?What can go wrong with the distribution block?
  17. If I can get the brakes working on the pump I'm going bigger cam.
  18. The cam isn't in a 351c so it's not really a monster.Its in a 521.I really want to think it's the booster but it holds vacuum.
  19. I've adjusted mc pushrod at least 5 times too.I bet I'm getting close to 5 gallons of brake fluid used over the last couple years.
  20. It's on manifold vacuum. Calipers are on correctly.I haven't gotten into proportioning valve or distribution block issues yet.I talked to gps brakes and got some advice on some things to check.My cam is 590/620 247/257@ .050 110lsa I'm making about 8-10" of vacuum at idle.Pump is supposed to put out 20".
  21. Booster seems to be holding.Brakes worked fine before I changed engine,new flex lines front and rear.Didnt change calipers because they looked good but they are unknown.Changed master cylinder all rotors and drums were turned.New pads and shoes.Rear wheel cylinders appeared to be new.Rear brakes adjusted properly.Ive been chasing this problem for nearly 2 years now.Dont seem like they are making enough pressure to " clamp".Brakes wont pump up.I haven't just started throwing parts at it yet because I thought it was an engine vacuum problem.Maybe I just need to replace and upgrade everything,should've done that to begin with but there was no issue before.
