Like a Carb CFM Formula. Hey, remember,these are only MY Opinions. I do a lot of Big Block Chevys , Hyd Street to Racing Rollers and Everything in Between. OK, there are good points about both of these.
Some people say if they build it , they know what they have.
And that's true. But it can get very expensive to piece an engine together. But, if you want to build a Monster Roller Motor,they can be a little tricky. If it's an Original Restothen put the Original Engine Back in it. Heavy , most cars don't handle as well with the extra weight in front.
