Interesting post. Just to generalize, I believe every motor depending on what you want out of it would be different. The combinations are endless as far heads , intake and carb. cam timing and operating range on just one engine combination. Header size ( diameter, length and collector size and design ) can very greatly. I am sure A56 will read this and chime in. Bottom line, there are people who specialize in that area and do the R & D and we pay for there knowledge. Will definitely be following the postings !
