Stretching Spring In Oil Pump

[hottrodd57]

i HAVEN'T SEEN ANYONE YOU SELLS A "HIGH PRESSURE" OIL PUMP FOR A BBC, ONLY HIGH VOLUME.
QUESTION 1

WHY DOESN'T ANYONE MAKE ONE?

QUESTION 2

CAN I JUST REMOVE & STRETCH THE SPRING ALITTLE TO INCREASE THE PRESSURE?

THANKS

[pat mccarthy]

if you run a HI volume the pressure will be more. less your past .003.5 on the rods and mains why do you want hi pressure ??? you can add a shim under the spring if you must

I Was Told That The "25%" Is Refering To 25% More Volume Over Stock Volume, Not Pressure.

Pressure is the result of flow. More flow means more pressure. Use a HV pump ............

or back pressure/ resistance from more flow that in turns takes more HP to run the oil pump and will take the gear off the cam or dist in time

[pat mccarthy]

why dose my oil pump drive look like a lickerish stick seen then 5/16 ford oil drives have the whine up look to them

[nitrowarrior]

those are the rubber shafts pat, better harmonics so you don't hurt the cam....

yes you can get them from the same guy that sells them rubber top pistons

[nitrowarrior]

Does he sell those rubber variable con rods that change length while running?

no he stop selling them you could not hold the press fit in the pin end of the rod

THE REASON i WANT A HIGH PRESSURE PUMP IS BECAUSE i HAVE BEEN TOLD NOT TO USE A HV WITH STOCK PAN. EVEN THOUGH I HAVE BEEN TOLD 5-10 PSI AT IDLE (800RPMS) IS O.K. ,IT MAKE ME REALLY NERVEOUS!!!! THAT IS WHY i WANTED TO RAISE THE PRESSURE. i WILL INSTALL A HV TOMMORROW THOUGH !!!!!!!!!!!! I WAS THINK ABOUT RUNNING 60W RACE OIL SINCE i WILL NEVER BE DRIVING IT IN THE DEAD OF WINTER(INDIANA). IS THERE ANY PROS OR CONS TO THIS??? THE MOTOR IS A NEW REBUILD, ALL THE PLUGS ARE INSTALLED, BUT I HAD THEM BUILD IT "LOOSE" ON CLEARENCES, BUT BUT ONLY ON TH HIGH END OF NORMAL. WHEN IT IS COLD THE PRESSURE IS FINE, ONLY AFTER DRIVING IT FOR 20 MIN;THE PRESSURE DROPS TO 5-10 @ IDLE, DRIVING AT 2300 RPMS IT IS 40-45 PSI. IT IS IN A 39 CHEVY COUPE SO THE WHOLE FRONTEND GETS HOT, IDLEING DUE TO RADIENT HEAT. I REALIZE THAt the oil is thinning resulting in the lower pressure, this is my first bbc. why don't they make high pressure oil punps like they make for sbc??????????? i am currently using 15w40 oil

[hottrodd57]

going back to the HV pump, I am using a truck oil pan & a 2quart oil filter. would that let me get by with the HV pump.?

[pat mccarthy]

yes they are great no more piston to valve issues no spark knock

Rats...I was going to order some....
