Has true duel exhaust and smokes out of the drivers side pipe only. Will die at stops unless I put into neutral or give it extra gas to keep the RPM,s up. Runs Decent at about 2000 to 2500 RPMS in second gear. Just running really rough. Any help would be great -RedLeg

The smoking out 1 side is not a good sign. Take care, Rick 68 Coronet R/T 440 & 68 Charger 528 Hemi,and 5 Challengers! 6 cyl, 318, 360, 383, 451

How do I check for a faulty lifter/s Nothing looks abnormal although I dont know how keen of an eye I have... The problem with the engine builder is I broke the engine in last june. It ran fine and then I had to weight to get it shipped where I am stationed so the warrenty I had was for the break in period but it is passed.

There are two Rockers that slide from side to side a tad.. This could be where my Tapping noise is coming from? 1977 D-150 Warlock 360/727 2021 Challenger T/A 392/M6 Its pronounced Dirte'

How long did you run it with gas in the crank case? Because it is very hard on the bearings. I also would due a compression test on all 8 cylinders to see what you have and post the results . 1969 Dodge Charger 1969 Dodge Superbee

Engine Noise Out of curiosity what is the oil pressure reading on your engine from cold to hot? Also check to make sure your rocker shafts are installed correctly. The oil holes in the shafts should be facing down into the rockers. If they are facing up you need to turn them over the other way. Are your rockers factory hydraulic type or adjustable? Can you give a breakdown of how the engine was built parts wise?

Taht does not sound good , check each rocker to see how loose things are ,there shouldn't really be any lash . snap a picture and post it of the cam , that does not sound good. Oh and lose that POS air cleaner , that is a FIRE waiting to happen ...
