Some years back there was an article in one of the automotive enthusiast publications about putting a big block Chevy engine into a shopping cart. Sure it will fit, if you don't mind all the custom fabrication of special parts to make it all fit.

You can put virtually any engine into a CR, and likely someone out there already has tried your combination. Just depends on your resources in time, patience, and finances. Yeah, everybody wants to make their car a little different for originality sake, but just having a Cobra makes you very different than other cars on the street. Just having a brand new 35 year old automotive legend is going to make you a popular guy. Just how popular you're not going to believe, until you start driving it and having some fun. Keep it simple, reliable, and maintainable.

More conventional setups such as the 351 and 302 Fords will get you on the street faster, and with less hassle than less mainstream combinations such as your 4.6. No Chevy power in a Cobra please. Automotive blasphemy.

You'll get some of the best advice available here, and the first piece is don't spend a dime on parts from the shopping guide until you check in here first. Things have changed dramatically since that manual was published.
