110 and under LSA/ICL/ECL
Who is running low LSA/ICL/ECL anything 110 and under.
Post up motor specs and dyno if youve got it.
Any drivability issues?
Also interested in anyone running a DCR higher that 8.8 on pump.

5.3L shortblock
214/212 .600/.571'' 108/108
#862 heads
- 2.00'' intake valves
- mild valve job
- .030'' mill
- .043'' gasket
10.3 SCR, 8:5 DCR
-3* overlap @ .050''
35* IVC @ .050''
Impressions:
Cranked up right after initial cam install. Only problem now is while the motor is hot, coming to a stop, it may try to die. I haven't researched yet to figure out what needs to be adjusted.
Dyno Results:
Soon to come. I want to do it today, but...

Ive noticed you like more duration on the intake, why?

I'm only idling at 770-rpm. Nothing 'too' low. I'd like to fix it without raising the rpm.
-Flattens out the torque curve with an intake restricted motor. If you need examples, let me know.

Ill take any graphs you got cmcguigan2000@yahoo.com thanks
On the idle I had mine around 750 in gear and had similar problems after chasing my tail with all the idle air tables(there are alot and they all play together) I just bumped the idle to 850 to be done with it. Ive messed with all of em including getting the iac counts around 30 yada yada yada.....blah blah blah after months of tweaking I ended back at square one bumped the air table a little and raised the idle.

Im just wondering if biasing the intake is restricting the higher HP numbers.
I'm sure you remember where I mentioned running a cell count with HP Tuners during a 1/4 mile pass to see where you spend the most amount of time. For me, I spent the most time during a 1/4 mile pass @ 4400.
