    I had the slant 6 replaced in my 65 dart a while back and the good running slant came from a buddy who got it from a buddy. Nobody knows what year of engine /car ect. All I know is it is a 225 slant6 with 1 barrel carb. Here is the stamped numbers on passengerside
    7 225 P 5 162E
    Casting numbers 0487 & 530-12 on the driversside

    I never bothered to figure how to determine the year. But, the 225 means it is a 225 cid engine. The "E" means cast crank. that is important, as the cast crank engines started in 1976. The block, crank, rods, and bearings are different then the early engines. Another thing, the newer engine has a larger crank/converter pocket then the 1965 engine and requires a crank adapter if using the 65 trans.

    I need to upgrade to a newr 904 tranny anyway and the engine came with the tranny and it's torque converter. It's weird that it's a mid 70s block since it has solid lifers and adjustable rockers

    Upgrading to a newer trans, will require a new shifter, speedo cable, and driveshaft.
    Slant six engines used solid lifters, and adjustable rockers, through 1980. Except I understand there were some hydraulic lifter engines in the late '70's for real world testing.

    Hydraulic lifters started for the 1980 model year.
    Before then, all of the slant sixes had solid lifters with adjustable rockers.
    Another easy way to tell a 170 or 198 from a 225 without looking at the numbers is to look where the water pump and head outlets are.
    The short deck (G engines) have a very short hose connecting them while a 225 (RG engine) has a longer hose to connect them. They are roughly an inch longer on the 225.

    No, 1980 was the last year for solid lifters and 1981 the first year for hydraulic lifters (except for an unusually large production test run of hydro-lifter Slant-6s during the 1978 model year).

    Not quite. The 170 is the LG (low G) block. The 198 and 225 both use the RG (raised G) block, so the 198 and 225 have the same longer bypass hose; only the 170 has the shorter one.

      Thanks for correcting my post, Dan.
      The 1980 thing was mixed up, I meant to say that the last year for solid cams was 1980 and in 1981 they went with hydraulic cams.
      And as for the 198 thing, I thought I was right because a few years back, I looked at a '72 Scamp that was for sale locally, and it was coded for a 198 and it had a rebuilt engine in it and had the short hose.
      Come to think of it, the guy was kind of a sheister and I'll bet he put a 170 in it and kept the original 198.
      (I didn't end up buying the car BTW)

      My 1980 Volare/ Canadian model had hydros.
      I bought a complete running 77 car for the Solid lifter engine core, and pumped it up just a bit..
      Turns out the 77 was a Super Six and I eventually used the trans and rear end too.In another car mind you.
