After building this Cleveland I believe I need to make some adjustments. Its a 351 CJ with open chamber 4v heads. The block has the moroso oil restrictors installed to their specs. The whole engine is a full roller. Hydraulic roller lifters, hydraulic rollir cam, roller lifters and the Milodon 9qt pan and high volume pump. I know NOW that a hydraulic roller lifter shouldn't need the oil restrictors so what are my options? This car (67 Cougar) will be a weekend driver at best/ cruise in and car shows. I started building with taking it the drag strip once in mind but not anymore. My friend who is a Windsor guy say if we replace the hydraulic roller lifters with solid roller lifters we can leave the oil restrictors in the block and not disassemble the engine. Others, who I feel are probably correct but i want to be lazy and not yank this motor from my freshly painted money pit car, say I should just take the motor out and pull the restrictors. Not to sound like a big wimp, I'm just frustrated with this and would like a plain cut answer that makes sense so i can get it done right. Thanks again and hope some 1 learns from this.
