    LD 4B tells a story...

    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...

    318 balancer on a 360 crank advice needed

    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...

    New PCV Valve whistles

    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...

    318 and lock up converter Balance

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

    intake gasket location thingys (that's a technical term)

    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...

    Help please - new? style 90 degree oil filter adapter

    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)...

    source for excellent 90 degree oil filter adapter gasket set

    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...

    318 and 340 motor mounts for 1970 Dart

    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

    compression on a 318

    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...

    D-66 questions

    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...

    using a 64-5 LA intake on a 66 and up LA motor

    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...

    How to identify "302" heads???

    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!

    small block heads for a long distance cruiser

    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...

    correct paint source for 1970 340 engine

    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...

    building a long distance touring car

    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...

    318 oil pan/340 windage tray

    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...

    Stamped block numbers below head

    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...

    Help me identify this 360!

    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...

    Indy/Edelbrock TA style heads

    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...
