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

If you don't think a 318 can run, then you may be the one stuck in the 80's. There are some seriously fast small cube motors now, welcome to 2021. Not being rude or controversy. There was a guy right here on FABO that offered to races those 422 for $$$ with his 318. We are away from the discussion, just say'n....

Bet he's got more than $3K in it. Also bet it's not even a 318 but tells everyone it is. Bet it's also huffing a lot of nitrous. Just like having a roller cam 512" low deck with a 383 pie tin on the air cleaner. "Yeah, it's just a mild buildup with parts I had layin' around, nothin' crazy. Wanna race?" But I digress.

I'd like to see some of these fast 2021-technology small cube motors. Are we still talking about your young man with a 4 door Dart 318 running 8 seconds on a 3 grand budget? Can't keep moving the goal posts. Thought this whole discussion was about low-budget street motors.

There was a guy that used to be on here many years ago out of the northern Midwest somewhere, victory273. Matt I think was his name, had a machine shop. Ran this '66 Valiant in NHRA SS/K with a 273/4 speed combo. That was sick ride, think he did OK with it. Very well thought out and well executed car. He was a machinist so he was able to do his own work but he very likely had $3K in the heads alone.

There was another NHRA stock '65 Valiant several years back with a 273 from the Pacific Northwest, this red car driven by Angela Bushmaker. They were in J/SA or K/SA. I believe they had it in the 11.70s which is not bad for that class. Another very well scienced out car and not cheap in any way shape or form. I was into this thing, so cool.

But these "fast small cube" cars are really not what we're talking about, right? NHRA class cars are close to pro level pieces and are generally high dollar efforts, even in the middle classes. I'm just trying to prove I'm not biased against one thing or another and that I've actually taken some time to learn about unusual combos. I'd take a solid lifter 273 over any 318 all day.

Again, my overall disagreement here is with your premise that spending $3K or under on a free 318 will net a better result because the 340 block will eat up too much of the overall budget. That's a non-sequitur argument, I'm not sure you can correlate two such disparate ideas while trying to make a comparison.

Really though, nobody is steering any budding hot rod kids in the wrong direction or giving them bad advice by suggesting they build a 340. I'd even go so far as to say it might even be better to discourage someone from spending any money on something that's marginal at best and ultimately wind up being disappointed in the results.

Maybe you or someone you know had a hot 318 that ran OK and it surprised some people but that's not the norm. Regardless, it seems like you've become stuck on this idea that these little **** motors are somehow more capable now than anyone had ever known before. I don't think so.

Either way, I'm glad I still have that extra 340 and roller block 360 so I never have to have this silly argument with myself. That is if I ever build another small block...
