continued... next concern is making sure the oil seal can press in. Read one comment that someone with this aftermarket intake ruined a few because the diameter was too small. the seat diameters on both seem to be close so ill take my time pressing it in if possible.

Update: Didn't get anywhere with Mancini. I've found OEM covers that would work on ebay as a back up, As well as a source here. I've been measuring and test fitting my OEM cover and the NEW one. All the bolt holes line up, the crankshaft seems center in both openings visually. The only issue is...

Yeah that manufacture must have bulk produced the covers and they are sold all over. Figured that out after I got mine and started researching after the fitment issue.

Cool, thanks for the link. I'm shaving material off the bottom to match my OEM Cover to test fit.

I already painted it. It may be wall art now. I'm gong to shave a bit off of it (1mm or so) to see if it could fit. I did find a few on eBay to consider. thanks

Yes sir, that was pretty much the response from them. No tech was available to talk to. I did follow up today with a winded email, including this thread and full information and photos. I did state the cover is not a direct replacement for a 71-72 318 LA OEM 2951698 COVER and would machine...

I tried it with a placeholder gasket and prying the cover down from both water-jackets it was just off to get a bolt started. I think if I just shave a bit it will fit. everything else looks to align and the crankshaft does center in the front seal. Well see after I shave it with a grinder.

The mancini specs state it will fit all. 273-360 But, after looking around online its is the same cover offered by every single autopart site. Fits: Small Block 273/318/340/360 & V6 With 9.600" Standard Deck Height, Raw Aluminum Note: This is a late model timing cover. Early engines have a...

I'm going to clean up my original and glob up the water jackets with RTV adding to what was there when I popped the cover off. I'll go the grinding route on the oddball aftermarket to see if I could make it work.

I did call Mancini. They stated it is a direct fit from original molds but "aftermarket reproduction" so there could be differences. I figured atleast the tolerances would be the same since Mancini was stocking it. One thing I have found out is that this casting is being offered in all the...

In the middle of a timing chain replacement. 1971 318 LA block. I purchased a new timing cover for my Duster from Mancini racing because the OEM cover has bad corrosion at the water jackets and about to penetrate cover in many areas to the internals of the timing chain. With the new cover...

I used a camera bore scope to inspect things and I've rotated the engine to visually check for wear also. I had some misfire at idle develop and that lead to this teardown. I've had the push rods out and check the lifters also. The timing chain slack seems to be the issue. I could rotate it 10...

I will do that! thanks for the tip!

Passenger side and driver side currently.

I don't have the intake off currently and man I wish i would have sealed the threads I have two that leak a small teaspoon of oil every now and then. Maybe I can loosen slightly and get a small amount on the threads while its cold

I'll definitely swap the shafts to the correct direction. I have time, I'm waiting on a timing cover from mancini anyway! Thanks for the great feedback

yes the rocker shafts are backwards. oops! The rockers do align and the push rods do align as well It has ran fine also. the push rods are hollow.. maybe that helped oil?

It seems my rocker shafts were installed backwards! Possibly when the engine was rebuilt in 2010. I purchased my 71 Duster in 2017. New to Mopar's & learning. I have driven and worked on it since then approx 22k miles. It was rebuilt in 2010 71 318la, bored .030 over, stock heads, comp cams...

Hi, I'm interested In the set if you still have them. One question, Do you happen to know the wheel width and backspacing needed with the spacers? I have 18"x7"F, 18"x8"R small bolt pattern currently and damaged two wheels. looking to go the the large pattern for replacement wheels. thanks!

2843675 head castings on currently. This engine was assembled at sea level. I am just doing minor parts upgrade. Not shooting the moon and making sure I'm checking all my bases for an fun wrench'n weekend project soon. Thank you for your input!

I'll look into it, lol

Gotcha, I'm going to have to do that at teardown. I'm Cruise'n to carshows for now... But it is good knowledge of all the things I need to consider while puting the plans and parts together. Thanks! I've only built a fox body mustang from the ground up before. Same Denver altitude 306... 69'...

I'll see about getting that measurement down a spark plug hole. May take a bit. But thank you for the feedback here.

Is it ok to reuse pushrods lifters and head bolts?

Woah! Thanks for the ideas! Are you a wizard or something!? Cool combo ideas! I do have a line on a 360 magnum for $600... Hmmm!

Dang, unfortunately it doesn't say in the paperwork I have... Just a general master parts list. +030 pistons +030 rings, etc... I did scope the block through the spark plugs awhile back and the piston are flat top... I'll have to investigate more there. Thanks for your input!

Hi, I'm at altitude in Denver... My current setup: 71 318la bored +.030, stock 318 heads, stock lifters, comp cam Thumper (20-600-4 279/296lift), 340 intake, 1/2" plenum w/ Holley 4150 600cfm carb. Hughes 3000stall conv., a904, 276gears. I have a set of X heads and Weiand stealth intake (port...

Yep sounds like the handle end dull thud...lol!

I'll check that to. I do have a missing exhaust manifold bolt... Thanks!
