My 340 4 speed with an 850 TQ and 3.23 gears will get 15-18 going 70 mph on the freeway... Driving mine down from Grand Rapids MI so i have a 350 mi drive to get there... best part about the weekend is the drive there and back.

Agreed. Very happy with Brad Penn oil in my 340.

Even if they are working fine in 1st and 2nd?

Strange issue came up this year. 340 is running great but when I get on it to 6k in first and second I then go to 3rd still at full throttle but at 5k rpm it falls flat. I noticed this once last fall but it went away. Anyways any thoughts? 69 340 4 speed w/ 3.23 gears Lunati 60403 with Hughes...

Brad Penn!!! proper zinc levels for the old valvetrane

Ran into this EXACT issue with mine last year. This is what I did to help/fix this..... -Like you stated, i cut the existing bolt holes on the top side so the TOP of the header port was the same height as the TOP of the exhaust port. (no need to weld up the old holes, they will just be an oval...

By far the most noticable difference was the elimination of all flat spots throughout the power band...especially at lower RPM's. Now that i have the timing set i can really tell a difference with 2k-5k power....great power thru 6k (which is all the higher i go). Overall a much more consistent...

http://www.forabodiesonly.com/mopar/showthread.php?t=193577 I didnt go the proper route when I did this setup. I went with a single spring froms Hughes (spring #1110) with matching retainers and locks vs the double spring that Lunati recommended. The single spring /w damper was approved by...

Fired right up last night. I'll flushout the breakin oil tonight and get some fresh oil in there....then drive it and see how it does. around 30 min to breakin the cam. Has a decent idle even after 30min of running so im curious on how it will sounds when its cold. I have some videos but I...

Breaking in the cam tonight. Ill try and take some videos.... Wish me luck

Primed the oil system last night. All the motor needs is the intake and valve covers bolted on.... Tweak the header ports and the motor is going in. Hot Rod Power Tour next week will be its debut drive

Once the motor is wrapped up, I have to modify the headers to match the newly ported heads.....cant wait to feel the results.

Ready for final assembly today.

Pushrods just came in the mail. Thats all that I was waiting on.

The build starts today. Pulling the motor tonight and sending the heads out for machining tomorrow...... more to come.

The last few parts that I ordered were delivered yesterday...Time to send the heads and intake to the machine shop. Let the build begin. (Hoping to get it ready for the Power Tour)

I ordered a pushrod length tool today from Elgin

Do you remember the rough cost to have those made?

Correct. My worry (as flyfish mentioned) is the overall length. Since my head has not been decked, and everything is in stock form, I figured that these pushrods would work length wise.

Has anyone used these pushrods? Comp Cam 7821-16 In the item description they are sold as LA 273-360 "Hydraulic Lifters w/Adjustable Rocker Arms" Any input will help. These would be used on a 1970 340 w/ stock J heads using 273 adjustable rockers. Lunati cam w/ hydraulic lifters Comp Cams...

Awesome! I have yet to hear any negative responses with this cam...

Absolutely! Nice to find Mopar guys at big car events. I'm trying to get my dad to go with his 70' Challenger T/A

Have rest of the parts ordered. Goal is to get this all ready to go for the Power Tour. Hoping to do the Detroit to Muskegon portion. Looking forward to the performance improvement, or "hoping" for an improvement.

Wow! Im going to hold you to it! haha Lunch is over...back to work.

Ordered this cam on Friday afternoon and it was on my doorstep Saturday morning. Not to bad. Starting to get all the parts needed for the cam/valvetrane upgrade. Hope this helps the 340 wake up a bit more.

Ok. Never knew that formula. Thanks
