451 Build For the 67 JC B'Cuda

Let me start this off by stating that I have never done this before and I don't know what I'm doing. I'm just some guy on the internets reading stuff that some other guy on the internets told me is this or that.

What i would like to do is build a reliable and daily driveable/road trippable 451 stroker motor with a target HP of 550. If what i'm asking is unreasonable, i will default to my opening paragraph.

So far all I've got is a block and the shopping list shown below. What I'd like is for y'all to tell me if I'm off to a good start or wildly off base here.

I have not yet listed a cam as i haven't found what i think i need yet. Some guy on the internets told me that if i want to make power with a tame idle i need a cam that has high lift, short duration & wide lobe separation.

The car is a 67 barracuda 4-speed 3:23/8-3/4. I would like to put a Passon A855 in it but at the very least it will get a passon 4-speed OD treatment.

My list is missing a few other things here and there but i think the meat and taters of it all is there.

So what sayeth ye, oh Some Guys of the Internets?

Good approach for a beginner, so congrats on that. Making a list and keeping track of things is the way to learn. Personally I'd scratch a few things from the list. You do not need a girdle and you shouldn't need the steel caps. I'd skip the head studs also. I would not buy the FiTech, take the money I just saved you from the girdle and caps and use it to step up to a good Holley system such as the Super Sniper or a Terminator kit. You'll thank me later. I'd also build a 470 rather than a 451 as long as the compression ratio is ok.

Buy my book and read it a few times then take the drive to Indio and talk to Brian at IMM. He can build you a very nice 451 using the 240 heads. It will easily make 550 to 600 hp with a Performer RPM intake (or Trick Flow intake) and the Super Sniper kit. You'll have a ton of power and if you get the EFI tuned correctly you'll be able to drive it anywhere with good fuel economy.
