Carb recommendations for my 340
Oh boy, I hope that I don't open up a can of worms here, but I've never seen a Q- jet on a mopar. Not saying that it hasn't been done or won't work. Does the Q- jet require some type of special linkage for the throttle and for the transmission. What intake manifold will accept the q jet or does it require a adapter? I known a guy who used to be good at tunning a Q jet because he couldn't afford a holley. Again I'm just asking
I remember seeing those QJs on Mopars, IIRC in the late 70s.
As to special linkages, no, just the typical KD stud.
I'm notta fan of sticking a TQ on a square bore intake, with an adapter. Thankfully Mopar has a nice cast-iron spreadbore intake, but it is a big-port; and I'm notta fan of installing those on small-port 318 heads. Yes I know, it's been done, but all you gotta do is swap it out for a small-port intake and make a note of the difference in drivability at low to mid throttle settings, and specifically in the throttle response. In 50 plus years, I've done it about every which way you can, and for myself, I'll never run a big-port intake on a small-port head again.
Of course, I'll never run a 273 again either, so long as 360 cores are plentiful, lol. Think of a 360 as the ultimate bored and stroked 273, lol Set one up right, and it will do everything a 273/318 can do with near double the power and/or torque.
Well getting 30 mpgs out of either one does take a little more ingenuity with the 360.
Some say the 273 revs faster,
Well I tell you what, car for car, put your 273 in gear, and pull up beside me, and let's go!. I'll even give you a headstart, and ask me how much I don't care that your 273 might neutral-rev faster than my 367. I say might, cuz you're gonna need an electronic timer to measure the difference. And while you're 273 is busting a nut trying to keep up, my 367 is gonna be cheering you on from the return road.
lol
Back on topic,
I'm pretty sure I've seen an aftermarket, small-port, spread-bore intake, back in the day.
As to your previous question as to spreadbores, IIRC, the AVS's were also spreadbores, just not as exaggerated as the TQ.
