i have a question on intakes i have a 72 340 engine mildly modified stock hi po exhaust manifolds my question is i have heard the ld 340 is the best intake followed by the rpm air gap then the weiland stealth .the problem i have is the range of the ld340 is 2500 -7000 the rpm is 1500 -6500 the stealth is idle -6800 .is the ld 340 to hi for a street car would i loose low end tourqe same question on other intakes i now have a 70 cast iron intake will either of these intake greatly increase hp thanks
Sounds like some bench racing going on here. Hands down the RPM is the best all around street intake, tried tested and true..
more curiosity than anything i keep hearing how the ld 340 is the holy grail of intake for small blocks. iam going to change i was just wondering if i would see any gains .
I have drag raced with both. The LD is a good intake but has an issue with vapour lock in the heat of the summer. The air-gap does not have this issue and is by far the better intake..
has any one used a weiland 8022 stealth intake if so any good are ports for a 340 or 318 any opinons on it
Never tried the Weiand manifold, I would say use the Edelbrock Air Gap RPM if you want the best of both worlds, great bottom end for street-ability & great throttle response, plenty of top end power for your set-up, with out all the fuel/intake heating issues.... The LD-340 is a great old manifold, it can be used also, but block off the heat risers, to help keep the intake cooler, but the water passages, will still heat the front & rear intake runners, a cool dense charge of fuel, is best for all conditions... IMHO

I have a 70 340 in my 73 dart swinger It has a 750 holley on top of a rpm airgap manifold....I have to tell ya I love the performance! You cant go wrong using the air gap manifold!!
i have decided to go with a edelbrock thunder series 650 cfm with a performer rpm i was going to go with a air gap but heard about a lot of problems in cooler weather.is anyone running this set up is performance good am i losing alot with out the airgap anything special i have to do to the intake,is carb big enough thanks
