    How to destroy a 440

    Well that's not comforting. Wonder if there is an issue with Stealth heads and the intake seat press fit? They use A356, which is the preferred material.

    How to destroy a 440

    The punched rocker wasn't the failed valve. My thought was seeing evidence of the rocker hitting the edge of the retainer (multiple places) and that is what started the chain reaction. Owner admitted she took it to 6000 RPM a couple of times, and with that stock valve train subjected to dual...

    Pinging 505 help

    Over the years I have mostly run Autolites. Champion on occasion and Nippondenso too. Even tried the Bosch platinum when they came out in the late 80s. Never had good luck with NGK even on my dirt bikes. Maybe it was me not knowing much back then but ND always worked in the bikes.

    They have that logo on the runner and the chambers look the same.

    How to destroy a 440

    Thanks for that info on Eddy heads. I didn't know. RPM or iron and it may depend on her budget. After paying big bucks for the car fixing this engine is peanuts.

    Pinging 505 help

    Are you running an extended tip plug? If so you need to run a recessed tip. If the plugs are long reach try Autolite R3935. The main reason is the short ground electrode will dissipate heat much faster than that long electrode found on long reach plugs. In my case, running an iron head BB...

    How to destroy a 440

    You definitely want to seat the rings and that can only be done with several repeated WOT blasts. But you don't hit redline that soon.

    How to destroy a 440

    Yep this will be built to withstand her lead foot. I use 3/8" push rods and iron adjustable rockers (or similar) on every performance build that requires more than stock valve spring pressures. Springs and weak parts do crazy things at high RPMs and I like all the rigidity I can get. Weak...

    Sunroof coupe. Nice. Mine was a leaf green 72T sunroof coupe. 2.4 MFI. I'm also a member of the R Gruppe and was friends with Cris Huergas (RIP)

    :p Yep sure did! I just thought it may have been a little rude asking for her to pose for pics.

    How to destroy a 440

    HA! Thanks a bunch! Yep, I built my 72 911T and it managed to stay together. That was a fun build. I didn't pull the engine out of this car or ever saw it in person. Here is the car 1970 Dodge Charger

    Either factory iron or Eddy performers.

    How to destroy a 440

    I only met her when the engine arrived. And she was wearing a skin tight mini dress and a white leather jacket with MoPar and Charger logos. Me thinks this is a tactic to get the price down.

    How to destroy a 440

    I have no idea who built this. The car was purchased from a dealer in TX for a whole lotta cash.

    How to destroy a 440

    I have not considered a warranty but will back up my work somehow and anything I offer will be conditional. Not offering a 5/50 but should do something. Most shops do nothing that I'm aware of. Time to get advice from some machine shops. I'll be installing it so will verify the cooling...

    How to destroy a 440

    I agree. The rocker is the first thing I saw with the valve stem gone and spring sitting loose. Looking at other rockers they are hitting the edges of the retainer. After I pulled the head off the intake seat was gone. Well, not gone completely. Just got spread throughout the engine.

    How to destroy a 440

    Yes, Eddy dual plane intake and one plane telegraphed all the shrapnel into 4 cylinders. Quite effectively I might add.

    How to destroy a 440

    Sleeve is the plan for the block. Heads are scrap. Maybe go with iron or Eddy, which do not seem to have seat failures that I know of. I'm a bit leery on Source heads from what others have reported over the years. Many say they are fine so really can't say.

    How to destroy a 440

    Can't know for sure if it was over heated before she got it but according to her there was no indication of it. Yes, running too hot can cause the seats to fall out. But still, a properly made head should hold up to normal heat cycles and the occasional over heating. I don't know how old or...
