Melling M55 oil pump
I had heard some years ago about horror stories with oil pump breakage on Melling M55 pumps for sbc after melling redesigned them making them thinner.
I was reading up on more of it a little while ago and found a article that said Melling recommended it be replaced with the Melling select oil pump. I looked into those and they want $75 for it which I think is rediculous, especially considering the original M55 before the design was changed you could abuse it every which way and never have a problem and it only cost $20 bucks.
It seems I had heard that melling went back and improved the durability of the M55 after getting so many complaints but I can't seem to find out for sure. If anyone knows if they improved it or not I'd appreciate it As we plan to use one on a sbc were building to go in a 89 Ford Ranger 4x4 and we don't want to run into any surprises. Thanks for any info.
