dont forget those 5/16 Philips head fine thread bolts Mack used originally to hold the old style shell to the headlight panels either.....

been some years since i tore a 237 head apart, do they share the same seals and tophat oil shields??

I agree.nothin is original anymore and who knows what some one did. Google search for 673 or711 valve seals shows different results to.guess I'm looking for a part number for those oil shield s and the thick square cut seal that goes inside them.seems to me years ago mack sold the whole kit in like a blister pack with the tophat shields and seals?

There must have been a year these came out?63 711 I'm doing heads on has the tophat collarette s to hold a thick probably 1/2 or 3/8 seal.a bunch are broke...1965 711 I took apart for parts has totally different intake valve spring retainers, with a liner and a common o ring around top of valves?

Anyone have a part number for the tophats that hold the seals? Took.one motor is apart that had no seals......the other had seals in these tophat things but about half are broke. Of course no one you talk to at mack has a clue...

late 61, early 62 was about the cut off for 'stock' colored frames. after that they were black stock. thats not to say you still couldnt order them colored but to simplify things Mack went with black frames, bumper and fuel tanks

sounds like your better off finding a truck already built. the motor is an easy change as long as you stick with a 237, 250, 285 anything e6. Matt Pfahl is the one to talk to or Kevin All. they have built many and know what fits. the front axle gets tricky as the U bolts in a B model are a weird spacing. i know some IH and Freightliner axles will fit

on this taboo topic again. workin on a 711, new heads and top end. anyone have a part number for the valve seals on the intakes? one i pulled apart for the heads had NO intake seals, other motor with a good bottom end has 5 out of 6 seals and the last had an O ring someone put on. didnt Mack use to sell a kit with the metal shrouds and washers with the seals with them????

please dont paint frame in rustooeum, you wont be happy. it will be chalk in less than 6 months. acrylic enamel is not much more expensive or nasan epoxy black...

wont draw enough air facing forward to make a difference honestly.

Matt Pfahl... wheres your expert input??

looks like an R column was swapped in with an MB steering wheel and a 237 with real jakes. what a Hoss

Been a while but didn't they make 18 studs then 18 studs with the bigger corner studs then finally the 20 stud fire ring one? I know my end707 doesn't have grooves cut in head but has the 237 fire ring gaskets on it. Can't remember but I think the liner was cut??

i know none of the Gurus are on here anymore. my end707 has the 20 stud, 237 head gaskets and fire rings. another 711 im working on has the 18 stud heads with the big corner bolts. when they went to the big corner bolts, did simply ream the hole out in the gasket for the bigger bolts or did Mack actually make a bigger gasket??? and is the 3029-8213C - head gasket - EN707/END(T)673/END711 with 18 studs the newer version with the corner bolts bigger or the older version ?? btw Mack is in love with that part number. they want $258.77 a piece for head gaskets

looks like she was restored back in the good old Tidewater Mack days.. thats the fuel tank Bob use to sell as a replacement
