Facts? Reason? What a joke you are. I have actually built these street motors. Not race car stuff, not Trailer Queens, not Dyno racing, or not bench racing. Look it up, I don't have to do anything, or prove anything. The numbers are in the NHRA records. I'm not the one saying something can't be done, or telling someone they don't know what they are talking about. You keep believing in "Magic" and BS-ing in a thread comparing the cost of a HP 340 or HP 318. In Class racing it is about airflow. Not bore size. You don't even know what the conversation is or about. Wa Wa 360 Wa Wa.
Lighten up, Francis. I’m not sure what your argument is and why you need to make it personal?
The 340/360 engines have a 4” bore while the 318 does not. That's a fact. I don't know about you but when building an engine and am given a choice between two blocks with the same external dimensions but one has a larger bore, I’m taking the larger bore EVERY time. Going by physics alone, the larger bore will always make more power because there is more up-swept volume and more volume translates to more air/fuel which = more power. Maybe you wouldn't make the same choice? If not, tell me why.
Also, I'm not sure but are you saying you have personally built NHRA Stock Eliminator 318 combos that held records? if so, please school me because I am forever fascinated by what class racers can do with marginal combos. What chassis in what class? How far under did you go, what elevation, temps. etc.
If you actually have been through that process (I have not myself but know some people that have) then I'm sure you would know it's an uphill battle and that a $3,000 budget wouldn't even be a drop in that bucket. Apologies if I did not interpret that correctly.
However, if you are using the Stock Eliminator angle to cite an example, its not really a valid point because class racing combos are highly specialized pieces. The same would hold true whether we're discussing a 318 in a '77 Volare wagon, an '82 4 cylinder Turbo Mustang or even a FWD Toranado.
Again, unless I'm missing something, the original point of this discussion was whether it's worth it to buy and build a 318 if your budget is $3,000. I say no. The other part of the question was whether or not a 340 is "better", to which I answer yes, every time, for the reasons I stated already.
I believe the reason this discussion has become relevant now is because it's not 1979, it's 2021. 40 years ago, 318s were left for dead because no one cared to bother with them. Going by what people have said for decades, presumably you could just make your way over to the local junkyard and pluck a 340 out of a '74 Road Runner for $50. Whether that was true back then or not I don't know but for sure it ain't happening now!
Standard bore 340s are obviously pretty scarce these days and rightfully command a high price when available. It makes sense, that's just basic supply and demand. Even the "resto" blocks that Mopar was casting 25 years ago are worth their weight in gold now if you can even find one.
But since finding a '74 Road Runner in a local junkyard that retains it's original 340 is not a realistic possibility anymore, people are probably looking at the crusty 318 they have sitting in the shed wondering what could be done to it to make it more fun (because it sucks in stock form). Problem is, no one wants to spend money on this idea because the fact is, it does not add up financially, especially when the cost of machine work is involved. Lipstick on a pig and all that.
Even if you think the supply of LA 360s is drying up, there are millions of 5.9 Magnum engines out there that would be a better candidate for a first-time or budget build over an old LA 318. Even if you're a bucks-down kid just starting out in the hobby, I'd still say to find a 360 or a 5.9 Magnum to start for the reasons I've already stated. It's not an emotional argument, it's economics based on facts and reason.
So without calling me names, telling me I don't know what I'm talking about or skirting around those pesky engine architecture facts, please explain to me why it's worth spending any money on a 318. Change my mind, I'm all ears.
