Today, dollar for dollar, is the 318 faster than the 340 ???

Well first off it doesn't cost $1200 for a roller cam setup in a magnum or a 340. You can easily build a good bottom end for around $1200. Nothing cheating out here it is what it is. Then get some magnum heads get a touch up on the valves. And pick a cam around $300. Nothing el'cheapo about it that's what it costs. So guess I'm trying to figure out why you think it cost $5000 to build a worthy engine?

Heck go get a reman magnum short block and throw a cam in it


Yeah, it is 1200 bucks or more for a good roller cam. I don’t use OE lifters on an aftermarket cam. Again, if like the OP you think it’s cool to keep building stuff like you had to do in high school I say fine. I prefer to keep up with technology and move forward. I don’t run stud rockers so a magnum head is never something I use in any build. So more fantasy land builds. How about you build this elusive 3k 318 world beater and let’s get it on a dyno and see what it really does.
