1st is oil pressure, new bearings-rods mains and cam bearings. two new oil pumps,valvoline 20- 50 vr1 only thing the same is idiot light and guage 70 psi at start up at idle as engine heats up pressure goes down to 20 at 180* and after feature light is on and have like 10 at idle. im thinking oil temp too hot from headers checked oil on dipstick with infra red guage its over 300* soon as pull dipstick. gonna relocate filter and wrap headers any ideas. checkad every clearance! next engine breaking up off corner and most way down straights. float level is right at screws barely touch car and it will come out a little. is this too high for circle track? last going through ignition modules two already this year msd in hei and one outta my dui unit swapped distributors after msd went bad and put my davis in from other car and it lasted two races put in anothe msd and two races ok so far checked voltage drop and resistance to ground every thing seems ok un plugged if welding thanks for any info

Not sure about the oil pressure issue. If you're saying that the new modules are fixing your other problem for a short time, I have a couple of suggestions about that. Make sure you use plenty of dielectric grease under the module when installing a new one. Also, make sure your motor is grounded well to the chassis. We were having a problem burning up HEI coils until we grounded the heads to the frame in the engine compartment. Good luck.

yeah i was thinking of runnig a ground strap to ensure good ground but i did resistance check to ground all over car and get same still gonna run one though the breaking up doesnt get solved with new module. is float level too high? carb is spotless so to speak just cleaned and put nuw kit in and prob still there.

I run into the same module problem on early 90s Chevy pick ups. Replace them & they would only last a week or two. The I started changing the pickup in the dist. too. Never had problems since. Just an idea!

Dan,

The way you have your float set is the way we run ours - no problems here. If I take the sight plug out and barely bump the car, I get a little fuel coming out of the hole. In other words, the level is at the bottom of the hole.

You running the baffles in the float bowls? We had that until we put them in and never had a problem since. I think they were $1 a piece, but fixed it for us. Good luck.
