Well, I calculate piston to valve clearance.Formula's, mathematics, can't because of..... shouldn't because of.... you'll be sorry on top of.....
wouldn't trade any calculations for first hand experience. some of us that have DONE it have testified. jury is in favor
never bent a valve in my life....
Have you ever installed a 340 cam in a 318 ??
LOL, It's a bit small for what I do..Have you ever installed a 340 cam in a 318 ??
ok, thanks.
AJ Foyt ran a 318 in his indy car producing 500 HP research his motor.
A lot of things to consider.
Obviously u have never tried this combination. Kim
But I do know the 318 LA head suck if that's what the OP is talking about. I have found on here when people say 318 they really aren't talking about a stock LA 318..well maybe the block. LOL! So to me the ops post as I read it means taking a 340 cam and installing it in an engine where everything else is LA 318. If he's talking magnum heads etc. or 340 heads etc. then things change do they not? Yes I have ran a cam and 4 barrel on a stock 318 and it fell on its face at about 5500 with 4 speed and 391s I try to not be full of **** but since you called me out I figured id elaborate. I believe I did reply to the OP "go ahead and do it let us know how it goes..." I wasn't against it in any way I have 340s so I don't dick around with 318s much. But that doesn't mean I never have...dicked around with a 318. I wont however go to too much trouble converting one to a 340, Id buy a magnum before all that .
Agree ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^Obviously...
I just might do this: I can pull the dual quads off my 318, and bolt on an original 2bbl and intake. The cam in it is a little hotter than a 340 cam, and the car does not have headers and still has the original torque converter and now 2.94 gears. Perhaps I can take it to the strip and see how much slower it runs than an original 318 2bbl Duster??? LOLAgree ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
There's always a lot of 318 cam threads when all of a sudden it has a 4 barrel and intake, headers, and some 340 or aluminum heads. Not the same as sliding a 340 cam into your stock 318-2 barrel with single exhaust.
I'm pretty sure I'll do this... ^^ and I'm pretty sure the car will go faster than any factory stock 318 2bbl Duster. I firmly believe if you are going to install a 340 cam in a 318, a 4bbl and dual exhaust should by all means be part of the plan. But I'm confident that it would outperform the stock 318 cam if it was left as a 2bbl.
As it should be faster. It will probably be faster without a 4 barrel/intake and dual exhaust. It might not be faster if installed without the carb/intake/exhaust addition. And along those lines, the 4 barrel/intake/dual exhaust may be faster then a 340 cam alone on a stock teen . It sounds like you have a lot of videos to make and testing to be done.
LOL... but what I'm saying is if I put a 2bbl back on my 318 with it's current cam, it would be about the same as putting a 340 cam in a 318 2bbl. Seems some think that putting a 340 cam in a 318 2bbl will slow it up. I'd like to see if it does....As it should be faster. It will probably be faster without a 4 barrel/intake and dual exhaust.

Yep. Which 340 cam are you using?LOL... but what I'm saying is if I put a 2bbl back on my 318 with it's current cam, it would be about the same as putting a 340 cam in a 318 2bbl. Seems some think that putting a 340 cam in a 318 2bbl will slow it up. I'd like to see if it does....
It's a 272/.455 cam, a little hotter than a factory 340 cam. So If I go back to a 2bbl, and the car is a little faster in 2bbl form than a stock 318 2bbl Duster, then that pretty much proves that you can add a cam, like a 340 cam, to a 318 2bbl and it will still add performance.
At what rpm? How about needing a converter and/or rear gears to make it work. (318 with a 340 cam and nothing else) Asking for a friend.
I think my car fits the bill of these two quotes perfectly. Stock converter, 2.94 gears, but 272/.455 cam. Will it be like any other 318 2bbl ??? Slower??? Slightly faster??
That would be a good test. There sure seems to be a lot if negativity about a 318 not being able to handle a 340 cam. No bottom end and at least a converter to make it work. Is it really that big of a pooch from say idle to 3500 rpm or is it just nobody knows how to tune a 2 barrel and distributor so the engine won't jump out from under the hood when shifting from park to drive? 340 cams sure don't sound that radical.
I have run this cam in my stock LA 318 with a 4 Barrel Holley it is still an affordable kit from Summit. Actually I still have one in my 318 but that engine is stiing in the corner, I have the same cam in a 340 with flat top pistons, and am going to run it in another 340 . street applications only not a racer. I run my Fox body at the track.
Was that a traction issue, or a tuning issue? Sounds like something was amiss!
