Posted from page 3 post #46:

All measurements at 0.05 Tappet Lift

Small Lobe - OEM Spec
Intake Duration - 165.7
Exhaust Duration - 182
Intake Lift - .2097
Exhaust life - .2303

Small Lobe - Delta Spec
Intake Duration - 184.5
Exhaust Duration - 161.5
Intake Lift - .2589
Exhaust life - .2101

Big Lobe - OEM Spec
Intake Duration - 202.2
Exhaust Duration - 182.7

Exhaust life - .2305

Big Lobe - Delta Spec
Intake Duration - 206

This is a stage 1 set-up with emphasis on torque. There are way more specs I can upload but I think these are the major ones people care about.

That's why I replied that no one wants a virus.... It's more like a 70 year old bottle of scotch you found in the basement lol

I meant to imply that the trend is spreading like a virus!!! It's good though, we need to inject some life into our platform.

Have been talking to a few people and they have said that installing a camshaft will drop compression - is there any truth to this?

What hp gains are we looking at with the stage1+ cam as in a before and after results?

Would there be similar gains if you just used astock camshaft and adjustable cam gear and advanced the timing by 10*

and lastly have Delta cams put there prices up from $100 - $600 ?

Thanks in advance for your help
