    Waste of a good short block ?

    Just pulled the 340 from a 73 Roadrunner I bought (I know it's a B body, but there's more advice here) ..... anyway, I knew the 73 motor was a wheezer but, lo and behold, I got a '70 block (and hoping internals) , but rest of the assembly (727, heads, exhaust man., intake man., all 73 correct)...

    Move this pig ! 340 B body ....

    I still have my 70 340 Swinger - but couldn't pass a deal on a 73 Roadrunner - all original 340 car, bone stock except for an Edelbrock 750. Being heavier - and "neutered" in 73 - it's a dog compared to the Dart. I would do a 440 swap, but it's a 95,000 mile original so .... what can I do to get...

    90 degree adapter question

    So I'm eliminating the adapter - from what I understand I will be removing the threaded filter retainer (circled in "sublime" below:) and this will thread through plate and into block - correct ? I gave it a shot this weekend (!" socket) and couldn't budge it, but wasn't "serious" at the...

    90 degree adapter leak

    This is the second time I'll be re-seating it on the 340 - not sure what gives. right now it leaks right at startup (cold) then it'll back off when engines warmed up - not pretty on my ceramic headers. Any tips/tricks for this time around and/or is there a shorty style filter that'll get in...

    motor mounts question

    So my old 67 had the biscuit style mounts (as I assume they all did) My guess is these did a better job of isolating vibration (rubber) verses the 73 style mounts I have in my car now, which as you know, are solid. Are there any mounts that provide good/better vibration isolation ? With the...

    70 340 air cleaner question

    Was there only one style air cleaner for the 70 340 Swinger ? This'd be the one right ? Found a decent one for 250.00.

    Intake manifold "guide" pins

    Regarding the valley on my 340 - there's two small pins pressed into the front valley and one in rear with corresponding holes in the cork gaskets - I need to pull these out to get proper alignment with the Air Gap - plan on silicone only on front/rear. I'm assuming this is fine ?

    rocker assembly question

    68 340 motor - x heads : the five spacers with bolts between rockers is it the two wide ones on either end with the three narrow in the middle OR two narrow spacers on either end and one narrow in the middle. Wouldn't be asking if I could find a decent pic - I think whoever rebuilt this last had...

    340 oil pan gasket question

    Rebuild gasket kit cam with oil pan gaskets (rubber ends) that do not have the 6 little "nibs" that go through the holes in the oil pan ends. Can I use the smooth type with silicone or do I need to order one with the nibs ? Last kit I bought had both styles. Also - any tricks to keeping the cork...

    Will I go to Hell if ...

    I paint my 340 block black ? It'd sure look right with all the other black and green on my Swinger. Nuthin's original or numbers matching - I just don't want to be put in "time out" by the Mopar judges :bootysha::bootysha: Thinking black block, black Mopar valve covers and air cleaner, chrome...

    Piston height question

    I'm installing TRW L2316 in my 340, )the picture attached is not mine , but shows the same piston installed above deck) mine are .030 above - I'm going to check valve clearance this weekend. Is there a chance I won't need to shave these ? I had the old forged domed 340 pistons in there prior -...

    Fuel return line question :

    Mines long gone (73 car) - Do I have to run one and if so where to (cannister's long gone, too) What about a filler neck from an earlier Dart that was vented ? Rather not spend the money if there's alternatives. Thanks.

    Ring gap question ....

    .030 over 340 - file fit moly rings - TRW forged 10.5:1 flat tops - may add 100hp nitrous shot - thinking .020 top ring/ .024 second from what I can find (.005 per in ) ?

    Piston height question w/x-heads

    Pistons are L2316 TRW flat tops - installed they're about .035 above deck. I noticed in the Edelbrock build-up in Mopar Muscle with these pistons, they shaved .035 with the Edelbrock heads - I'm assuming giving them around 0 deck height. Anyway, the pistons I'm pulling out are ancient TRW domed...

    How difficult to file fit rings ?

    Was given a set of Mopar moly file fit rings - I'm either going to use them (.030 over) or maybe see what I can sell them for and buy a regular set. How tough is it (and time consuming) to do this yourself with the right tool of course and are they worth it for a street vehicle ?

    Currently a .030 over 340 w/mild porting on X heads, XE274 cam, TTI exhaust, Airgap and 770 Holley, auto w/3000 stall , 3.91 gear. For the money spent, will I bolt on and go "wow"?

    In my Swinger :.030 over, Air-Gap intake, Street Avenger 770, mild ported X heads and may go Eddys, TTI headers, 3000 stall, 3:91 gears and manual brakes.
