Thought I would share some pics of the parts car 73 340 4 speed charger with a 71 340 I bought last month at an auction. Not an A body but I bought it just for the 340 and I finally pulled the motor out last week, car was stored inside and the engine still has coolant so hopefully all is good...

I have my small block factory X heads apart to set up springs, clean up the bowl area and check them over. Looking at replacing the intake valves, a couple are a little beat up around the lock. My question is what valve has anyone used as a replacement? I have the old TRW V2811X in it now...

Pulled the X heads off my 340 to get them set up for new springs, while I have them off I am going to clean up the bowls a little, here is a pic of one intake bowl, do these look like factory cut from the valve seat into the bowl?

Pulling apart my 340 to swap cams. Pulled the 273 rockers and pushrods out and found one pushrod had the ball end come loose from the tube. The end was laying in the lifter after pulling out the pushrod. The tube looks like it was beat up a little, so it has been run like this for a while. This...

Swapping out my current MP 508/280 solid cam for the MP 557/296 solid. Wondering if I should advance the cam 4 degrees or run it straight up? Provided I have enough piston to valve clearance. Its mostly street driven, only make it to the track a few times a year. Doing bowl and port clean up...

Going to give the old 557/296 solid MP cam P4120655 a try in my 68 340 dart. Looking for a set of valve springs to run, don't care for the MP springs, any suggestions? Looked at comp 995's or 987's so far, not sure if I am on the right track or not but comp recommends them for similar comp cams...

Thinking of trying the small block MP .557/296 solid cam, calls for the MP 3614542 dual springs. The retainer for these springs is MP 4452033 and is listed for single and dual MP springs. My question is, are they the same retainers used as the stock replacements? My X heads are already...

Wondering if anyone has used this spring and if it is a true drop in with stock retainers. This is the MP cam I have and it recommends stock 340 replacement spring that I am using but I plan on replacing. I know the comp 901 spring is a drop in and will work, just looking for a little more...

Has anyone ever used the Mr.Gasket 988G 4 degree offset cam key on small block? It is listed for chevy crank key and mopar 354-392. Doing some research some said its the same as the small block mopar cam key. It does look the same to me.

Just pulled the heads on my 73 340, looks to me like the pistons are the high compression replacement pistons. Pistons stick above the deck and have 2 valve Reliefs. I can't find any numbers stamped on them but they are standard bore. Here is a pic, tell me what you think, just making sure...

Just curious if anyone has used this cam? Part # p4529963, Its an old oval track small block cam, 108 installed center line. A buddy has one new in the box he never used. I see MP recommends their dual valve springs for it also. Machine work to get the springs to fit my heads will cost more than...

I have a low compression 73 340 and was thinking of having the heads milled to gain a point of compression. My question is has anyone know how much is needed to be milled to gain a point assuming they are at say 72cc now? I will have the heads cced and measure how far down the pistons are to...
