That is the question. Whether ‘tis nobler in the mind to suffer the slings and arrows I may get from this august college of y-block knowledge for what I’m contemplating, or to keep the y-block and be relegated to rolling speed bump status when climbing some of the hills in my area. I’m on the horns of a moral dilemma. I’m kicking around the idea of swapping a 390 crate motor into my ’55 Merc. A cursory comparison of building my y for more power vs a mild 390 says the 390 would be the cost effective way to go. Here’s the rub: I’m as certain as I can be that my engine is original to the chassis. There’s something to be said for the “rightness” of keeping them together. So what say ye? All opinions are welcome but probably won’t affect my decision.
