I gotta take the timing cover off my 455 to re gasket it and figured I'd replace the oil pump and fuel pump while its off. any great advantage in the TA pump? Dana.
NO! Unless you count increased wear and pressure on your cam bearings, cam gear, and timing chain as a great advantage. A stock pump with good clearances will provide all the oil volume and pressure you will need. A better buy would be TA's booster plate, oil pump gasket shim kit(to adjust your end clearance), and adjustable regulator.
This comment is based on an experience with a stock 73 350, but you might find it useful. I put a new rear main seal in the first 350 I put in the Regal. The rear bearing looked great! However, the cam was wiped out as I discovered after I ran it for awhile. I stuck a used cam in it, but it still made some horredous top-end noise. I figured what the heck, since its junk, I'm gonna try something. I stuck a 70 lbs oil presure spring in it to really oil the top end more. The engine actually quieted down a bit. I pulled the engine six months later and pulled the oil pan. The oil was metallic copper!!! I mean BIGTIME metallic copper! I pulled the rear main first since I knew the bearing was good. Not a trace of nickel on it, it was pure copper. The rest were too. I'd have to say this is good proof of what happens when you bump up the oil pressure on an otherwise stock system. It seems the old adage of ten pounds for every thousand RPM holds true.
thanks, guy's the pump I have in there now has only a few thousand miles on it and I get good pressure with it so I will fight the urge to pull it off and change it for no good reason. I'll pull it off and inspect it though. Dana
10 psi per 1000 is a good rule of thumb, just wait till your moters oil presure drops then i would go to the booster plate, and a adjustable regulater. i know from experience to much oil presure on a mostly street driven car can cause problems.Larry i had to throw my 2 cents in there
The booster plate worked well for me...at idle pressure. My pump cover was pretty scored from the gears, and definitely needed a new surface to throw oil. It was a nightmare to install in the car though. Next time, I'll wait until the motor is out of the car:laugh: No really, it's not that bad. I could probably get a new one on pretty quick, now that I know what I'm doing. Thanks to Larry and JW.:TU:
Because soooo many people ask for it! Mike and Dave attempt to sell the plate and regulator, but unless you've asked the question here or snooped around this site, you just don't know any better. If Mike doesn't stock it, the customers will just go to Poston's and buy it/ Poston still swears it is the best cure for oiling woes.
if i had a trailer queen, that had an all out race moter, that i was turning over 7000rpm i would probaly run the high volum pump. i think the big problem with those pumps on a steet moter is your idle presure is to high i was getting close to 45psi hot and is was 60+ at cold start when i tried it. also if you have a moter that has a lot of miles on it and ever a booster plate isnt enough, that pump would help you get buy till you could rebuild the moter
