I thought I would ask the Mopar experts out there for their thoughts with my situation. Some background: I brought a 440 six pack engine to a builder to freshen it up with a more modern approach. The engine ran great except I had some bad gas clogging the filter and carbs. A freeze out plug...

I’ve installed Trickflow 240 heads with Harland Sharp 1.6 roller rockers. I think the rockers are just touching my valve covers because there’s a some tapping noise. I’ve been told these rockers shouldn’t make noise so I suspect the rockers might be touching the rockers. Does anyone have any...

I have a 440 six pack build in a 70 Charger with the 240 Trickflow heads and would prefer to keep the HP manifolds. I ran into some issues and would like to know if anyone has some experience with the install of these heads on 440s. I tried to install champion plugs and ran into interference...

I have these valve covers. Some should belong together as a set but I am not sure which. The dirty one I think was from a 68 440 engine. The other covers have openings for grommets or oil filler? What side do they belong on? What say you? Thank you in advance.

I have a set of Hurst Shifter Ram Rods I located in my tool box that my brother used to own. I'm looking for some clarification of the application. I know he used to work on his 1968 Coronet 440 and was setting it up to race. There are a few pictures I found on the internet but some of them...

I have had some trouble finding a decent throw out bearing (looking for a BCA NB1625 or National bearing replacement- no China crap) for my 18 spline 4 speed. After searching the internet I see that there is a possibility that the Ford Bronco used the same bearing 1.625 bore? I see a bearing...

I just installed a set of freeze out plugs, installed the engine during a recent refresh and one freeze out plug is leaking. Maybe I didn't smack in as far as I should? I will try pushing it in further tomorrow. If I have to remove it and replace, does anyone use a particular sealant with the...

I am installing a 4 speed trans soon and wanted to look into using a pilot bearings VS pilot bushing. I've had the last pilot bushing come out for some reason (don't know how long it took) and I wanted to look into using the bearing instead. Anyone have opinions/experiences with them? Is one...

I had some adjustable pushrods made for my 383. I used a setup like this with my 440 and was very happy with it. Stock stamped rockers. Once I get zero lash what preload would you recommend? One rotation? 1-1/2 rotations? Thank you in advance.

I have a 1970 383 with closed chamber heads and was wondering if anyone had spark plug suggestions. Standard Holley 4 bbl and magnum cam. Closed chamber iron heads should bring it up a half point? Thank you

I’m getting ready to assemble an engine soon. Does anyone sell the tubular stock manifold nuts in stainless for a 440? If not I’m going to make them on a lathe. The original ones rust. Thanks

I just had a valve job by an engine builder on BB cast heads. I asked him about grinding the valve stems even and he said he didn't because he could find a spec for it. I paid a lot to have these heads done. Don't engine shops finish Mopar heads by grinding them even height when finishing the...

Can anyone suggest a set of roller rockers that fit under the covers for a 383? A set of push rods to suggest with the rockers? I'm just using a stock magnum cam. I don't want to use the stock stamped ones...... Thank you

I have a 383 out for repainting and fresh heads. I could use some feedback from those who have had success with engine paints. I haven't had much luck with the VHT spray. Even with a fresh block washed and degreased engine block. Eventually it bubbles and flakes. I met someone recently that...

I am in the process of some engine changes/tune-up. As I was cleaning the gasket material off the intake gasket surface I looked inside and noticed that there is an oily sticky residue coating the intake runners. It looks like an oily tarnish. Almost wet but sticky. Not dark. Light brown. It...

I want to replace the bearings, seals, and possibly the synchros while I have my motor out. I have heard that there are some poor quality parts out there for doing this. Any recommendations for a vendor source?

I am replacing a cam and head setup on my 440 - 6 pack using 240 Trickflows heads. Four speed, 3.54 gears, #4000 car. I have heard that hydraulic roller lifter cams have advantages like durability, better oil selection without zinc, broad torque curves etc. but after viewing reviews of products...

I am planning a build sheet to include a "Hot Street" Hughes cam SEH2832BL-10 in a 440-6 pack engine with 10.25 to 1 pistons with the closed chamber 240 Trickflow heads. I am currently able to use my power brakes with 11 vacuum using the existing purple shaft .284/.484 cam. The Johnson...
