Okay, never had this happen before. I got a 318 out of a 5th avenue. I'm just trying to see what the compression is before I throw it in the barracuda. I got the motor mounted to the transmission a 727 with the converter. I bolted up the starter that came with the motor, but to me it just seems...

A customer came in today that owns a machine shop and was buying a set of factory lifters for a 454. (I manage the Parts Department at a GM dealer) We got to talking about lifter quality and.he said the factory stuff is the only ones worth a darn anymore. I told him I was surprised they were...

So I have the new block and rotating assembly at the machine shop now. He is going to look at everything next week, and unless something isn't usable, we will be moving forward with my rotating assembly. I am heavily considering changing cams because the Lunati 703 didn't produce very much...

I am moving over to this forum from the 4 speed forum as I have determined that my issue is not transmission related. I have a 70 Dart 340/4 speed. The motor was out last winter for the 4 speed install and while.it was out I installed Edelbrock aluminum heads and a lunati -10200703 cam. I...

Do these have inner springs or are they just dampeners? I have a new lunati cam with .494/.513 lift and the instructions say to pull the inner springs for break in.

I degreed the new cam in the 340 and verified installed centerline of 106, which matches the lunatic cam card. So now I have #1 at TDC. The crank dot is at 12 o clock and the cam is at 6 o'clock. Do I need to roll the engine around one full revolution so #1 is ready to fire? (Cam and crank at...

I am installing a new cam and heads onto my 340 and noticed that my cam thrust plate does not have a oil dripper OR the special bolt with the hole in it. Is this ok? I didn't put the motor together, a machine shop did sometime ago. It doesn't have but maybe 500 miles on it. I just decided to...

I am going to be degreeing in the new lunati cam soon and want to be sure I have the right tool(s). I have this kit, but have never used it. Small Block hydraulic flat tappet. Should I get this to along with it? Or get a solid lifter and an adjustable pushrod? I will be degreeing the cam with...

Hey Everyone. I am moving forward with a set of edelbrock aluminum heads for my 340. Since I am going to be in there, I am going to have my hydraulic cam reground. Ken suggested a custom grind with the following info: 224/[email protected] 480 lift 112 Lobe (due to EFI) He did say determining...

Hey guys! I am not sure which head to go with? I have a 68 340 with factory J heads on it now. The motor and heads are not original to each other though. Edelbrock 60779 Edelbrock Performer RPM Cylinder Heads | Summit Racing or Edelbrock 60179 Edelbrock Performer RPM Cylinder Heads |...

I have a 70 Dart with a '68 340 4.10 and soon to be 4 speed with Passon OD gearset. I rebuilt the engine about 10 years ago and admittedly just wanted to get it running. (I didn't really follow any build, other than following the machinist recommend needs for the block.) Plus I was pretty...

Hi everyone, I'm chasing an engine vibration (or at least that's what I think). 70 Dart 68 340 A500 OD transmission Neutral converter Neutral balancer The vibration can be felt in Neutral when revving the engine to 3-3500k. It's not as pronounced as when it's wheels on the ground, at speed...

Guy on FB is selling these for $100 shipped. I already bought a pair for $85 that are wrong and don't want to make the mistake again. I have a hard time telling between the pictures.

I've been fighting a vibration issue see my other thread. So I leveled out the car on ramps. (Confirmed with level on sill) I went to check my motor level and it's not. Ugh. I then looked at my mounts and they are different passenger vs driver. I'm thinking I accidentally used the conversion...

I added FITECH efi to my car and about ready to fire it for the first time. I just verified my balancer TDC mark and it's dead on. My question is, how do I know if I am on the compression stroke? I set the piston stop and moved cw first, marked the balancer, then went ccw and marked. Then...

My 340 was rebuilt about 3 years ago, barely has 500 miles on it. I pulled it to rebuild the front end and paint the engine bay, that spiraled into a full blown resto-mod mod It was storeid in my insulated garage, bagged. It had 5 qts of VR-1 10w30 and whatever coolant in the block, that wasn't...

Does anyone know the width rail to rail of a SB oil pan? I am going to be building an engine dolly (This one) but don't have an oil pan to test fit. Thanks!

Hi Everyone, I have a rebuilt 340 that has been broke in and driven approx 100 miles. I want to remove the engine and start body and paint work. That being said, I am not sure how long all that will take. I was planning on building a rolling cart (seen on the forum) to set the motor on...

Hello Everyone. I have a 68 340 with the Air Gap and am adding a Dakota Digital fan controller, which requires the temp sender to be electric. I have a mechanical temp gauge, so I need to purchase an electric temp probe. I have labeled the picture below with what I have currently. Can I use...

68 340 block .040 over KB Hypers recent rebuild (Less than 1000 miles) Been driving often (every weekend) with no problems at all. Initial timing at 18* total 36* We had a local "cruise" in our town a few weeks ago, so I took it there and it ran great was out for about 3 hours. I took it home...

Hello everyone. I need some advice on my ignition timing. It's a 68 340, steel crank. I put a new harmonic balancer on, because the old One spun on the rubber.. I replaced it with a summit OE 7.25 dia. http://www.summitracing.com/parts/sum-163273/overview/make/dodge Set the initial timing...

I have a 340 warmed over with edelbrock thunder avs carb. I am trying to set the timing via a vacuum gauge, but I get no vacuum reading from the passenger side port, unless rpm's are raised. I get an erratic reading on the drivers side that increases with rpm. Am I missing something...

In the process of checking torque on my headers a stud on the passenger side head broke. I drilled through it fine, but could not get it to budge with an easy out. Not wanting to risk breaking an easy out, or making it worse, I pulled the head so the machine shop can drill it out for me...

Hello everyone. I just wanted to share that my 340 is finally complete and am hoping to fire it this weekend. I'm going to be priming it tonight. I just had a question about fuel, what is the best way to get the fuel to the carb without having to crank on the motor excessively. I know when I...

Hi FABO. I'm getting real close to finishing my 340/904 trans for my 70 dart and am running in to an issue with throttle linkage. I am running an RPM Air Gap and an Edelbrock 4BBL. I have the factory throttle linkage but no kickdown. I would like to get the lokar set up for both throttle and...
