750 Eddy on my 340 .030 over with a mopar purple .509 cam along with 3500 stall and a 9" ford 389 gear set. The 750 works great with this set up. Oh I may add that I also have a Holley Blue electric fuel pump with psi regulator set at 7psi

Ditto. I had to do the exact same when removing my starter from my 340 and I have a mini starter also. The biggest problem I had was removing the electrical clip connector on the top of the starter while the starter was still mounted.

Headers look nice BUT over a short period of time the paint will burn off leaving paint flakes. I have sand blasted them, heated them up to the required recommended temp before applying the VHT 2200 degree High Temp paint coating which is suppose to not peel or flake. Within 100 miles the paint...

The key to this question is I have never used a torque wrench and once you have tightened the bolts down be sure to check and retighten them after the car has reached operating temp. They will indeed need to be snugged up a little more..

I have no studs on either exhaust end water holes. I have regular header bolts and I have not had any leakage problems..Studs vs Bolts? Does not make any difference.

STP oil treatment which contains zinc. I have been using this for the last 25 years in both of my HP SB Mopars and I have had zero issues..

Valve body bolts ? So I guess I will have to drain the fluid out to check this... Thanks

Ok guys in my 340 I have a 727 tranny with Trans Go Shift Kit along with a B&M Quick Silver Shifter with a Custom JD Convertor 3500 stall and a Transmission cooler and the problem I have is when the tranny is cold it shifts into all gears quick with no hesitation at all and I do shift this...

I am old school and people will laugh when I mention this but I use STP, which contains, Zinc at every oil change and I have been for the last 25 years in both of my SB Mopars. My motto is if it works dont change it...

I have been running Champs RN12YC with MSD 6A with Blaster Coil plugs gapped @ .048 in my 340 for close to 19 years and never have I had any issues with Champs..

Yes it is a 340 but automatic. I found the problem and it was not the tranny pan gasket which I thought it was, it was a bad O-ring on the dip stick tube. Replaced it and no more leaks.

Thats what I had heard also so every time I buy a bottle I read to make sure it does indeed contain zinc.

I have BF Goodrich tires and in the past I have ran with the whites out but then the white letters would be difficult to keep white looking. I think putting tire shine over a period of years took its toll. Tried everything under the sun so with my car being prowler yellow I decided to run the...

My recommendations in which I did just this same thing when my 340 was running close to 205 consistantly, Install a fan shroud and move your fan further back from the radiator and doing this will allow for more air flow over more of the radiator. I also have a 180 degree Thermostat and my 340...
