Default FE Experts needed possible rebuild 427 SO

Hello all,

I wanted to get your take on a possible rebuild. Here are the parts which I currently have:

- Edlebrock Heads ( already ported and polished)
Valves SS. intake 2.190 / 1.730 Exhaust
- Dove Rockers
Will change- Solid Roller Cam shaft 245 intake / 250 exhaust @ 50
Valve Lift 660 665
- Block 427 1965 Side Oiler
- Crank $427 Steel Crank (C9AE-A-6303-A) Will need to get bearings
Rods NASCAR (C-7 OEA) 0.080 inch wider
- JE Pistons
Compression 9.5:1
- Oil Pump from Precision Oil Pump (blue printed)
- MSD Dist with 6AL


The motor is currently assembled and running pretty good. The reason for the possible rebuild is because the oil pressure seems too low at idle 10-15 psi. The oil pressure does jump up off of idle to about 45-60 and increases to 70 max. Another factor is that a leakdown test was performed resulting in a 26 % leakdown.

I am still in the build process, right before I send the body out to get painted. I really would not want torebuild the motor later when the body is already painted.

Since I am thinking of going back in I will change the cam because the motor idles very smooth. I understand that Webers have this effect on motors but this cam seems like it is for more HP in higher RPM range. Also, I am undecided on the crankshaft and rods. I have heard that it is hard to find those bearings but my engine builder say" its not a problem.


What to do ?



I am thinking that the clearances are too loose in the bottom end.
