Dyno'ed My 360..it's a pig..what next?

I found this;
E3N is 270/280/112, and .050s of 215/225, and lifts of 440/465. This is another case of slow street ramps. The 270 makes a bit of a lope in the idle, but the 215 is just there to keep cylinder pressure up, hence the reason we hear no surge in the pipes.

#1) Here is what your combo might look like
Static compression ratio of 8.0:1.
Effective stroke is 2.81 inches.
Your dynamic compression ratio is 6.49:1 .
Your dynamic cranking pressure is 121.41 PSI.
V/P (Volume to Pressure Index) is 104...........................................104VP
The low cylinder pressure points to your low power output.
and the 104VP points to her being a pig

#2) Here is the same engine with a fast rate 215/112 cam, say with lobes of 39 degrees, making it a 254 advertised, and an ICA of 55*
Static compression ratio of 8.0:1.
Effective stroke is 2.99 inches.
Your dynamic compression ratio is 6.85:1 .
Your dynamic cranking pressure is 130.44 PSI.
V/P (Volume to Pressure Index) is 119............................................119VP
See that jump in VP of 14.4%? That's something you will really feel off the line, and the extra 9 psi will be felt everywhere..

#3) Here's an example of the earlier slow cam, but the compression optimized for it and pump gas
Static compression ratio of 10:1.
Effective stroke is 2.81 inches.
Your dynamic compression ratio is 8.06:1 .
Your dynamic cranking pressure is 161.44 PSI.Y
V/P (Volume to Pressure Index) is 139..............................................139VP
Notice the cylinder pressure now! That's a 40psi increase

#4) And finally the second cam, the fast-rate 254 AND optimized compression;both together
Static compression ratio of 9.5:1.
Effective stroke is 2.99 inches.
Your dynamic compression ratio is 8.10:1 .
Your dynamic cranking pressure is 162.48 PSI.
V/P (Volume to Pressure Index) is 149..............................................149VP
Check it out! now you are at 149/104= plus 43% stronger bottom end and midrange pressure over 160psi. Put a tune in that and roast the tires.Remember this is still "just " a 215 @.050 so your not gonna win money. But it would be a mountain of streeter-fun. And you will be able to drop some rear gear and hit the hiway, and pull some incredible mileage out of her.

#5) Of course the bug might bite, for more cam,lol, I mean if you're replacing pistons anyway, then you might like this;
Static compression ratio of 9.8:1.
Effective stroke is 2.86 inches.
Your dynamic compression ratio is 8.03:1 .
Your dynamic cranking pressure is 160.66 PSI.
V/P (Volume to Pressure Index) is 141.............................................141VP
This is with a 270*fast-rate, so about 230 at .050, about 2 sizes bigger than your current cam, so maybe 30 or more horsepower potentially. Notice the very small VP loss of 141/149= Less 5%, compared to the previous model, yet it is still 141/104 = plus 35% better than your current combo; same 270 advertised......

All of these above models were held to a pumpgas friendly maximum Dcr of about 8/1; so we are comparing apples to apples.

#6) If you went to aluminum heads you could pump up the Dcr to 9/1, and same combo as the last one could look like this;
Static compression ratio of 11:1.
Effective stroke is 2.86 inches.
Your dynamic compression ratio is 8.99:1 .
Your dynamic cranking pressure is 185.88 PSI.
V/P (Volume to Pressure Index) is 163............................................... 163VP
Hoooleee 163.... now there's a tire frier.........still with a 270 advertised......
I ran this on 87E10 at 10.9Scr.............................


Ok so what's the point?
The point is this; You can't just slap any old cam into one of these low compression engines and expect miracles.Many times the bottom-end goes away.

Do you need a VP of 163? Answer;no. But it sure is fun! This makes a real tire frier, from stopped to 65mph and beyond. You can put it in second and leave it there for hours.
How about 141? I ran that with my 292/108 and 11.3Scr. I thought it was weak.But most guys with 9.8 teeners running 268 cams are happy and they're running just 125VP. So I guess it's subjective. A stock 360-2bbl VPs around 120, and you might remember what that feels like.....lol. Hyup you read that right; 120. That's 15% better than your current combo with the 104VP. That's what slow-ramp cam can do in a low-C engine.
I'm currently running 153VP, and there's room to drop a lil, but only because of the rest of the combo.
So 140? I think that would be the lower limit for me. 140 blasts thru the gears pretty good with 4.10s in the back, but slows right down with 2.94s. 3.23s would be the lower limit for me, but I have a 3.09 stick, for a 9.89/1 starter-gear. With an auto, you can usually run one rear smaller and let the TC do it's magic. But since you already have 3.55s back there,in an 8.25;just leave them, it will just be funner.
So there's my analyses. More compression,a faster cam, and then the tune.Any carb but for you.....the 625 is fine.
