Flat tappet to solid roller...

Finally! :)
I did just over 100 miles today, took a LOOOOONG way to work and back in average traffic and some back roads and I am VERY happy with the result of this swap.
First off the car had higher oil pressure for first few miles when hot. It came back to 25psi (when in gear and standing still at 900 rpm) I had before after some driving. It idles really well at 900rpm and starts better when cold. I don't need to keep my foot in it when starting cold, only think I need to do is to press the gas pedal once before I turn the key and it runs at 700 rpm cold without any issues.
Second thing is low end torque and gas pedal response, the difference is more than I expected. On my way back home I accelerated once from stop light to like 4500/5000 rpm at 3/4 throttle and it was more than the car had to offer floored and revved up to 6500 with previous cam... Its in a different league and sounds very serous and throaty on higher rpm.
Third thing I noticed is that it runs colder by about 20 degrees for some reason. Normally in very slow traffic it would overheat, but now it reached 200 degrees max. When driving it was holding 180 degrees vs 200 before the swap. I must check what thermostat I have. I triple checked the timing and it is as it used to be at 18 degrees initial and 36 total so exactly what I had with previous cam. I need to figure out why it is suddenly better. Any ideas? Carb was not touched yet and it seems that with bigger cam it is probably a bit on the lean side now right?

After coming back home I set the valve lash at .0022" hot as cam card says. I am writing this with a nice glass of beer :) Finally it feels like job done!

My Duster became seriously fast street car after this swap. I have 29/12.5/15 MT Sportsman Pro out back and at 45mph when I hit the throttle in 3rd gear it spins the tires.

Thanks again to everybody that helped out with parts choices and for pushrods rescue :)
That was very cool!

Cheers guys!


Excellent.

I do hope you wanted to type .022 valve lash hot and not .0022. If not you'll,have an issue.
