Wrong, the D4B is aluminum as is the LD4B, both Edelbrock. The LD4B is for post 65 heads(intake bolt angle and size).

I ran the Comp cams 20-246-4, 468 lift. solid in my 65 recommended upgrade for the 10.5:1 commando motor. Motor ran killer. 65Dart - YouTube

Hey I know that car well, I would put a 340 in it that "looks" stock. That car is too original to change too much. Sure it would cost less to build the 360........but?

275 was way under rated. That number was all buttoned up at the factory to meet the emission standards etc. and make the cars insurable. 275 at what RPM? Real numbers on these were 300-320.

If they are late 64/65 heads locate an eddy D4B....great manifold

So we fired up the "new" 340 today. Have a slight vibration at idle. My buddy who is helping me with the install automatically says its the flexplate. Its a externally balanced 340/904 combo with a neutral convertor. I ordered the right one, b&m 10235 for sure. Any ideas would be great ...

If it fits 318s as the add states it would be a fit for for 66 and later 273 which would be a D66. A D64 will fit early 64/65 273 only with the funky bolt angle.

Try and find some spitfires on line, shorty headers, will work great as long as your goal isn't huge HP. I was quite happy with them on my 65.

Has anyone looked into this? A friend has got me wondering if I should investigate the possibilities of building one of these for may 71 Dart. Parts are cheap since dodge pulled out of NASCAR. He bought a set of heads and an intake for $900. He is building one for a Road Runner with a 750hp...

where did you get the heads?

Great help guys thanks. Ya, I took that picture with the choke part closed warming it up for the first time, turns out the linkage was binding slightly , enough for 500RPM. Not used to this new fangled cable bracket! loosened everything up, re tightened.....seems happy at 1000.

felpro for early 273 , perfect fit no leaks.

Ya that's the first thing I did so no leaks. Ah, Seems to be a bit better now I took the mixture screws out and cleaned everything. At least I can adjust them. I'm going to change the POS fuel filter tomorrow. I love my 65 :D. My 71 is still MIA going down to see her tomorrow.

Hey Scott, I checked for vacuum leaks , all seams goo there. Ill check it again though. I'm going to blow out the idle circuit, maybe some crap stuck in there.

I was reluctant to post this question because I feel like an idiot but after swapping my intake I cant get this car to idle below 1500 rpm, Ive checked for vacuum leaks and it seems to be good, set the timing to where the car starts perfectly (like it did before the swap) and played with the...

What would be the intake bolt torque spec for a 65 273. The bolts are 5/16 NOT 3/8. is 35 lbs a bit too much?

From what I know its all about the heart shaped combustion chamber. The swirl port design makes HP with small ports (1.78/1.50) . The small 57cc chamber should raise compression.

Does anyone know the difference between the 70 and up bypass fitting vs. the 69 and down fitting? both are 3/4 " NPT ?

bump, help?

Does anyone make a set of intake bolts for the 65 273 head? I believe they are smaller then 3/8 (5/16). Also I need the thermostat housing pipe fitting (to the water pump) as well as the one to the heater hose. finally installing the new" D4B intake I got 5 years ago).:blob: Where can I get...

What heads are on this motor, did you have to notch the block?

Thanks , 318 talk always stirs up a hornets nest. I guess its a tricky subject. These 596 heads are off a 79 318 cop motor so I am not sure compression will be an issue or not. I have an eddy performer 318/360 manifold as well as a brand new eddy 600. Cam is still up in the air but I know from...

I never said anything about chev motors in the first place, these heads are a bolt on for 50$ they have been cleaned and magnafluxed so I figured I would play with them. Eventually a built 360 will go in the car. I have my 65 to cruise while I play with the 71.

stock 318 with intake, carb , cam, 3:23. Just thought I would wake it up a bit for something to do , if I keep the car, probably going to spend some money and buy a real motor.

Ok, I cant find any 302s so these are available, but which ones? 4343646 or 4027596, both cheap and checked for cracks.

Anything wrong with these for a 318 build? (since nobody has any). http://www.napaonline.com/Catalog/CatalogItemDetail.aspx?R=MCYCHR4033_0243714669

If it starts leaking again while in the car it can be a *****. Better off to do it right.

Hope your right , I couldn't get them twice now. Thank god for members here.

Yes they do . I found out the hard way with 5 quarts in my driveway.

Not any more they cant
