    408 oil pressure issues

    I steer clear of Fram filters. I try using Purolator most of the time as I have comfortably put like 100,000 miles on their filters in the last 6 years across my drivers. Thanks for making sure to add that point to the list, as I want to be sure I am not leaving anything out. As stated, warmed...

    408 oil pressure issues

    So it still drops back down when hot. Quite possibly one of the most notable observations is that when a filter is fresh, I can easily get 60+ psi. After a few minutes, I will drop pressure and 40-45psi is about the max I'll have from then on. This is an F body with 2.45 gears so 5000rpm even is...

    408 oil pressure issues

    Have a mechanical guage, had the issues with 10w40 and have had the issues with 10w30. Reassembled it with nylon bushings on both ends of the oil filter adapter fitting and will soon test drive it to see if I still am having the same issues once hot.

    408 oil pressure issues

    Background- '72 360 based 408 with newer oil pump/pickup, 360 car pan and dipstick, '98 magnum heads with a hydraulic roller. Hot oil pressure gets low. It's been a few years since it got together and it hasn't seen many miles but it looks like I may have painted the oil filter mounting plate...

    Converting LA 360 to roller cam

    I'm using the old cover and I don't think I'm going to the new one anytime soon. I run an RV2 on my M1 to be special- if I switch I'll probably go to the '79-up style Sanden since I can. I have a Saginaw power pump as-is. I have a stock '96 318 Ram computer. I may end switching to a stock '98...

    Converting LA 360 to roller cam

    Just curious- was thinking this looks like the cam I want to run: https://www.summitracing.com/parts/lun-20200715 2000 stall 904 NLU, 2.45 gears, M1 MPI, stock Mag heads, manifolds now but plan to go back to headers. Plan to build a 42RE for it and probably swap to 4.10s. Was thinking Morel...

    340 crank questions

    340 cast crank were used in 318s. Pistons are heavier which's why the 340 had to be balanced externally with the same crank. IIRC my '84 302-head 318 truck's crank and '73 340 had the same cast #. That is the best way to sell a 340, with a car wrapped around it. And 'course the 360 stroker...

    1974 E44 engine sales code? 230hp 318?

    Very, that's the normal 2bbl code.

    Has anyone decoded their 340 serial number?

    The 318/360 light blue. That looks like it was stripped of its paint and painted red.

    Magnum swap EFI wiring

    Vans ccd those years? Know they did 318/727 vans with OBD-II. Of course all OBD-IIs can be flashed, just some will easier to use with your old guages not like the others will be horrendously hard.

    Has anyone decoded their 340 serial number?

    Junes usually are, I have a June '71 1972 model 340 with external balance and 915 heads, my June '72 340 had 587s on it. 340s were relatively low prodution, and '73 I think it was they started exporting them- but an older block being used on a newer motor doesn't seem out of the realm of...

    Yes and yes.

    Basic Magnum question: Safe maximum RPM on stock internals?

    Niners were like 3,900ish. The heavy late cars with all the options would hit almost 3,600.

    Whats the deal with 340s?

    Is that much worse than less power? Technically they're pedestal mount stock, many switch to ball/stud for cheap roller rockers. The teeners aren't awful, but they're substanically slower to speed and up. That same motor was used like that up to 1980. They also had a 2bbl version of the 360HD...

    318 simple bolt on setup for more horsepower

    Mine was like 23, lost a couple from the 318. That sounds more like it. I've always wondered why you don't hear much of people getting better fuel mileage with a 2wd than a 4wd that's a decent bit higher.
