Hi everyone

I got a real good deal on a 54 chevy 235 a while back. I was on vacation a couple weeks ago and decided instead of going anywhere I would change the 56 235 with three speed with overdrive for the 54 motor with a T-5 in my 54 GMC 3/4 ton. This motor purrs with the Pertronix ignition, Fenton headers, and the Holley Webber two barrel progressive carb. My first question is the oil pressure at around 15Lbs around 4 to 5 hundred RPMS and 30 to 45 Lbs while driving 1000 to 2200 RPMS around town. Is there something I should be looking for or is the oil pressure good? I have not taken this motor out on the freeway because when I put my radiator back in I discovered a major leak. I am using another radiator which also needs work. I don't want to create problems for my motor by running it hot. The radiator shop said the radiator needs new core which will cost 395.00 plus tax. Now the question are the aluminum radiators good? Is anyone using one? Looking on line Ebay it will be more cost effective to get one then to fix mine. I will appreciate any help on the oil pressure and radiator issues I am having.

Thanks in advance Steve
