Well I can tell you what I would use as a temporary cam with your low compression.
I would go with .550 lift max and no more than 230-235 @.050 and it seems to me that if stay in the 112-114 separation you have a chance for some more power.
85 ss 302 the reason im saying 112-114 is it seems that all the cams that call for higher compression tend to be 110 separation and less.
If you look at some of the AFM cams you will see what I mean, lower comp 112, higher comp 108-110. I think some more lift will help regardless of compression.
I will add this, borrowed from another stangneter.
The tighter LSA of 110 degrees:
- Increases cylinder pressure, cranking pressure, dynamic pressure, which can increase octane requirements.
- Increases valve overlap.
- Narrows the power band, and put torque at a more midrange RPM.
- Increases speed of engine revving.
- Initially gives quicker throttle response.
- Reduces idle quality and creates less vacuum.
- Decreases piston to valve clearance.
- Reacts better for carbureted engines.*
The wider LSA of 114 degrees:
- Decreases cylinder pressure, cranking pressure, dynamic pressure, which will decrease octane requirements.
- Decreases valve overlap.
- Widens the power band, and put torque at a higher RPM being more peaky.
- Decreases speed of engine revving.
- Initially gives slower throttle response.
- Increases idle quality and create more vacuum.
- Increases piston to valve clearance.
- Reacts better for fuel injected engines.*
