Bad day on the dyno...

Ty I hear you... I always told everyone
that the valves would float so I had a rev limiter

We also worked a lot faster and did not have to make
a million upgrades or make it pretty because running them
was more important.... kinda miss the old days
Loaded that car up many a times at midnight so I could
racing in the morning after working on it endlessly

I'm not?!

I remember when I build the engine for Hunk 'o Metal, and I bought nice components for that thing. Don't remember spending nearly this level, but that was 14 years ago. D'oh!

Back when air shocks, Keystone Klassics and those yellow Lakewood slapper bars were all you really needed? LMAO

This thread is making me think I should seriously consider an Accusump system when I plan my 383 build. I might take it on a road course one day. I'd rather not destroy my newly built engine since it's not a simple junk yard motor.

Glad you're making positive headway, Bryan. Good luck.

I was told many years back that my 69 Z/28 DZ motor
had a swinging pickup on the oil pump.. it never starved
for oil pressure although I did spin a bearing in it but I
think that was from changing the piston in the parking lot
at college after a keeper fell off my newly done heads
I am sure metal got in the engine from the parking lot hone

But I have never heard again about a swinging pickup.. does
anyone know if they actually had them and why not now??

Nope, the swinging pickup is a myth. The 302 oil pans did have a lot of baffling to contain the oil at the pickup more consistently.
I feel that with a properly designed pan sump, followed by proper baffling, there's really no need to have the pickup move in the pan.

The lotus can pull 2g's and with the stock pan that's a disaster. I installed a moroso road race pan and it's nicely baffled. I still take comfort knowing the accusump is there if and or when the pressure falls.

May of been a myth that the 302's had a swinging oil pump p/u. But they do or did make them

Yes sir, I should have been more specific. Swinging oil pump pickups are not a myth, they do exist, created primarily, but not specifically for some Mopar applications. I was referring to the DZ 302 Chevy engine. I've heard through the years many talk about this engine using a swinging pickup from the factory, and it's simply not true.
Someone recently designed a swinging pickup for the V-10 Viper engine, but I've not heard if it worked better than those designed decades ago for early hemi engines and 440's, which had a reputation of sticking in the wrong position. These were sought after for drag racing, and would swing front to back, for accel/decel oil control. Perhaps other types were tried in road race style engine applications? Not sure about that...

Thanks Scott for clearing up the Dz info
Back when I was 17 someone said something
and I figured it was correct. Nowadays I am questioning
some of those statements
