I don't know about a higher level of ingenuity, but I will agree with a higher level of technical knowledge. In your standard OHV V8 you stab one cam, degree it, you're done. I've built enough mod motors to know what goes into them. I think I said it before, but I'll say it again, I don't discriminate when it comes to the "manufacturer" of an engine. By the time I'm done building an engine, the only manufacturer likeness it has is the basic design. I don't even want to tell you how easy it is to put one cam in, perfectly degreed, 180 out on a mod motor. You won't know until you fire it up. It won't hurt anything, but it'll run and sound like garbage.
As far as big inch Mod motors go, as much as I'd love to see it, I don't think it'll ever happen. I mean, they've been out for over 27 years and there is only ONE aftermarket head for them. ZERO aftermarket blocks (unless you want to count some of the billet blocks I've seen for the Coyote, but I don't count them because they're not suitable for a street car). If it hasn't happened after 27 years, it's probably not going to happen, and if it does, the price will be ridiculous. There's not much point to a big inch modular anyway, not as long as TF is your ONLY choice of aftermarket head. Everyone knows that the only way to make big power on a mod motor is lots of boost, and they do that very well. Why would Dart, Brodix, or any other manufacturer go out of their way to build an aftermarket big bore block capable of big inches when the top end is not available to support it? Big inches are primarily for naturally aspirated engines, and no PI 2V, 4V C head, or 2V TF head is going to support a 400+ cid modular engine naturally aspirated.
No worries man, you're not polluting my thread.
This^^^ This is EXACTLY why I end up building more Chevy than anything else. It's not because I favor them over another, it's because the aftermarket is just so much more abundant. If someone comes to me and wants me to build them a Ford FE or 385 series I'll gladly do it. I'll sit down with them, go over their goals, and present their options and what it'll cost. I'd do the same with a SBF, SB Mopar, BBF, BB Mopar, Honda, whatever... it makes no difference to me.
In my case I came across a running 454 from a motor home with less than 70k miles on it, a TH400 trans in great condition, a set of very nice -781 BBC heads, a J&W SFI rated bellhousing for the trans, a Scat 4.00 cast crank, and an Eagle 4.250 crank... and I'm into all of that for less than $700 probably. Financially it makes sense for me to go with what I've got. I'm the sole breadwinner in my house. I support my wife, two stepsons, and my (almost) 2 year old baby boy. I'm ballin on a budget. If I could get my car to run 9's with a Mazda 13B for $19 then I'd have a little rotary in there.
