I have a 318 in one of my Darts that is mated with a 42RH 4 speed OD automatic, and has 2.94 gears. 8.5:1 compression, Edelbrock Performer intake and a 650 AVSII. It is a long distance road trip car. I believe that the current cam is not serving me well - 17mpg on the road, lack of vacuum for...

Just a reality check - are all stock stamped steel rockers for LA 318s and 340s interchangeable?

I have a stack of small block timing covers stashed and someone local needs one (currently has a mix of 69 and 72 parts with no way to see the timing marks). I pulled out the stack of 70 and up covers that I have and they have 2 very different seals in the lower hole: a smaller hole in the ones...

A couple days ago I was trying to reorganize a bunch of my parts hoard. I was moving intake manifolds around and noticed the difference between the ports on 2 manifolds. I was pretty sure they were both Edelbrock LD 4Bs made for the small port 273 and 318 heads, so I pulled them out and...

Please pay no attention to the balance issues that are inherent here. I am trying to mock up some pulleys and spacers to solve a custom accessory issue on a car that is 3000 miles away that has a 318, so I was going to use an engine that a friend has on a stand. The engine is a externally...

I just installed a fresh 318 in a Dart and got a new PCV valve from NAPA (Standard part). The thing whistles when the engine is running. It's so loud I can hear it in the car at 50 mph!!! So I switched it with the old, but completely functional valve from a different 318 - no whistle. I put...

Are all LA 318s internally balanced? Are lockup converters only set up for externally balanced engines?

So for many years I used intake gasket sets that had little yellow plastic pieces that fit in the gasket bolt holes (2 per side) and kept the gaskets in just the right place while installing the manifold. There is even a little recess in the heads that accommodates these clever little devices...

I' been digging through my parts to find a 90 degree oil filter adapter. I found the type that I'm used to - cast iron, but also ran across two like this: They are aluminum and have a shorter bolt and those two 'prongs' sticking out of the side. What are these for (what did they come on)...

So in looking for a set of gaskets to mount the 90degree oil filter adapter to my small block, I ran into this offering: They are put together by an individual with a history with small block Mopars for race and street. The big gasket comes from FelPro, the thick compressible small gasket...

So I have what I think are 1) a 340 and 318 passenger side mount. 2) a 340 drivers side mount and 3) a 318 drivers side mount All for a 70 Dart. Can y'all confirm this? 318 drivers 340 Drivers 318 & 340 passenger side

Does somebody have pictures of 318 and 340 mounts (the part that bolts to the block) so that I can sort out the ones that I have correctly? I should remember which is which but can't (old timers disease) Thanks

So since 318s were made with compression ranging from 9.2:1 to 8.2:1 where is that extra compression coming from? since the cranks and rods didn't change is it in the pistons? If you are rebuilding can you increase compression just by using pistons designed for a 68-9 318? or is it designed in...

I've been looking for an Edelbrock D-66, dual plane dual quad manifold for small port (273-318) heads for a long time. I finally found one and it arrived yesterday. Here is what puzzles me: It's clearly a D-66, It has the larger bolt holes and they are straight (not ovaled out). The manifold...

I'm working on a 318 and want to use a D-64 dual plane, dual quad Edelbrock manifold on it. opening up and changing the angle on the bolt holes is pretty straight forward (and doesn't have to be super precise), but I don't want to grind down the surface where the intake bolt heads seat. I'd...

Just like it says, I'm buying a 318 that is said to have 302 heads. How can I be sure that they really are? Is 302 the last 3 numbers of the casting number (which I think would be found under the valve covers along a port runner)? Thanks for the help!

I'm gathering parts to build a smallblock for a Dart that will be a long distance cruiser. It will be a 340 or 360 and I know that there are lots of new head possibilities out there. I want to use LA valve covers and intake. What are folks using that they are pleased with. A nice mix of decent...

Years ago I got the paint that is correct for my 1970 340 - it had a limited run (1970 and 1971 to March on 340s and a couple years on street hemis - 70-71 I think). Anyway, my water pump went up and I need paint so I can get my show car back on the road. Anybody know of a source that is...

I'm building a 1970 Dart specifically to use for long distance touring, like taking 101 down the coast to Rt66 across to Chicago then hitting the Nats and Chryslers at Carlisle and then doing it in reverse the next year. I'm trying to figure out the best small block to use in front of a 4 speed...

I just did a minor rebuild on a 75,000 mile 1970 318. It's in a restored street car - 70 Dart. I put the whole Edelbrock kit into it to give it a boost - carb, manifold, cam, lifters, springs, timing chain and gears all from Edelbrock. Also added a stock 340 windage tray. Started it up and it...

I'm looking for some information on the stamped numbers just below the head on an engine we are working on. The block is a 1971 360 casting and we think it is a Mopar Performance crate engine (early 300hp?). Anyway the numbers are HW560R3694. Across the number 5, at a diagona,l is stamped K-4...

A buddy of mine bought a 68 Dart that was somebody's project. He was told that the motor was a Moper Performance crate motor. It has a Mopar Performance dual plane intake on it. It ran pretty good so he just took it at face value. Now it looks like it needs a rebuild and I looked at the...

Is anybody using the Indy/Edelbrock TA heads for a small block? They are Edelbrock Performer RPM heads that Herb McCandless redesigned. Indy buys unmachined castings from Edelbrock and moves the pushrod holes away from the intake ports just like the old 340 TA heads. It all sounds great in...
