Never had a problem with rear main seal leaks until new 512ci stroker build. Everything went per "text book" during break-in except minor but anoying oil leaks. Cometics valve cover gaskets solved half the problem but two tries at rear seal area didn't help. Finally decided to bite the bullet...

Looking for set of BB headers for my run-in stand. The 512ci stroker is nearing completion but I have no vehicle in mind yet so trying to avoid buying a new set that would not be usable in future. I've welded all my life so capable of salvaging smashed or broken tubes. Would prefer a decent set...

Trying to top off my 440source -512ci (507") stroker with a TM-7 intake. Saw a few on $leez-bay but thought I'd check here first. Prefer uncut but heads have been shaved so expect I'll have to do some work to make things right. Not ready to consider another brand/style yet, as I'm happy w/ TM-6...

Short block is done. Heads are done, well I thought so. Cleaned, maged, ported, gasket matched, polished, hard exhaust seats, milled to cleanup, paint, & freeze plugs. While lapping valves I found small dot in #2 intake seat so back to machinist (I do most my work). Each time we touched it, it...

Ordered my 440-512-5075 kit today. Need to make decision on heads. Early 70's 3462346 casting (right in pic) will need new guides installed or Late 78' 4006452 casting (left in pic) will need hardened exhaust seats installed. Both have 81.5cc chambers & will be ported using DC P4120437 plastic...

A friend advised that a 65' D300 was @ PAP & had a BB automatic. Yep, 383ci w/727 lever shift despite push buttons on dash. Case #J2894014101535 isn't in my master list but falls around 68-69' so suspected it was swapped out. Took a chance & pulled it anyway. OK so drive shaft turned both ways...

What is the significance of additional ball (arrow) in reaction shaft housing? Shaft on right w/ 2 ball plugs (arrow) is from 74' BB motor home, left w/ 3 ball plugs is from 81' D100 lockup. Part numbers on housing are the same.

Finally finished assembly of 80's Speed-O-motive 451 low deck stroker. A few changes along the way but happy with results so far. Still looking for just the right vehicle & being very particular. Thought mid-70's D100 but thinking Dakota w/full fab chassis. Not very street-able but fun regardless.

Trying to order another bolt-in replacement sprag but the two top suppliers have discontinued them. Have always used the TCI sprag with good results after Direct Connection faded away. What other options are out there?

Could not find a air cleaner to fit my Holley 4500 dominator that looked good so I purchased Mopar Performance #DCC-5249807 from Summit, cut the center out of base to 7 5/16", flipped it over and am very happy with results. Will replace element with 4" high to increase flow. What do you think?

I've built my share of small mopars and started to check my "B" blocks I hoarded for years to finally get working on my first stroker. I have 2 early 70's that both mic @ 4.320+/- which is the bore for the 440 "RB", these should be 4.340 minimum. The markings are: casting- #3614230-6 dc-...

I have a A727 removed from a mid 70's truck with the following markings on the DS pan rail "PK 4058384-7326 3034". The case body has rough cast marking "188-1" on both sides of the bellhousing (mold markings?). I have found reference to a A727-RG but it included the comment that "an adapter is...

Looking for experience and advice on bypass hoses. I have purchased a Champion 3core (thank you challengergary) for my 65 V 200 w/69' 340, X heads, .508/292dur purple stick. I have a Ebrock Performer w/ Holley 4165 and timing at 18 static/32 total. Plugs look perfect. This is a true 10.5cr...

Anyone have a pic of the rear brake assembly with drum off showing spring placement and adjusters. Mine has been McGivered and doesn't look correct. It appears someone has replaced at least one spring from a "grab bag" of spare parts. I am waiting for a Maxi kit but can't figure out what had...

Just finished up assembly of original 69' 340ci +.040 10.5:1 and running on run-in rack. X-heads, Edelbrock Performer w/650cfm spread bore and 292/.508 hyd cam. Sounds great and runs for 10min then boils over and pukes about a gallon of water out. Heat cycled twice and re-torqued heads...
