I need a little guidance. I have not built this motor myself i only have a list whats in it. I tested my valvesprings with moroso valvespring tester. I got about 210-220lbs from each spring, does it sound good? I'll attach this list about whats in the motor in this post. Can anyone specify something about this camshaft, i didnt find anything about it on internet. Or is this cam any good for this combo? Car has run 10.5's on 1/4 mile with gasoline. Now fuel is switched to e85 and my pb was 10.9s on e85 with old fuel delivery setup. Now fuel pump, lines and regulator upgraded bigger and havent run since.

Thanks!

I see “.640 lift Engle roller cam”

The springs have worked satisfactorily so far, and they tested good.
Just leave them in until you feel like they’re due for replacement.
If that’s now, then you need some more physical data.
-installed height
-open force at .640 lift
-diameters(ID/OD)

Then you can sift thru some catalogs to find a suitable replacement.

The Red Flag I see in the engine build list is the stock rods.
I’d keep the upper RPM limit fairly conservative with those in the motor.
