Not quite right....it talks about the intake opening as the EXHAUST stroke moves twds BDC

Thx for all the information gentlemen. I have piston squirters so thats a plus.

Is there any other reason Pribe may be inferior?

LMFAO

Well it does mention most of the things you did! LOL!

But what I was really trying to extablish is if a retarded ICL would cause reversion....it sounds like 'not likely'

Yep...understand that...and my exhaust is rubbish! LOL!

You beat me too it! I googled and found a goid Hot Rod article explaining it.

Thanks for your trouble...I inderstand the issue now...and the fixes.

Surplus on Ebay - $390 US

Would this be an issue for a 500 hp motor with the SRT piston squirters?

Ive heard no good things said about Probe e forged slugs - but no one can tell me WHY they are inferior?

Any thermal dynamics or other research data out there to explain their bad rep?

Can someone provide a rudimentary explanation of what is meant by 'intake reversion'

- I understand it to be when the AF charge doesnt pressurise the cylinder properly....but I could be wrong....

What are likely causes?

No dist - computer controlled....think LS.

RE TIMING control - I think thats it mate. I'll need to verify it when the car comes back from the workshop...but sounds like the answer. I only just started using that feature so that would make sense!!

I am using an MSD 6013 ecu - lap top programmable - in a 6.1 Zhemi retro mod application. Carb inducted. The program allows for both base rpm timing curve and MAP timing to be added on a PSIa calibration. Problem - Even with MAP deactivated, and initial timing set at 16 deg, the 'real time' read out...

Cheers and thks for the input. Ill start some experimenting on the plenum side with some flaring of the holes using some old phenolic spacers I have.

Currently Im running a couple of four hole spacers on a dual quad application. Just wondering if there's any benefit in radiusing the edges of the four holes, to reduce the current right-angle between the top of the dpacer and the sidewall of the holes? The match btwn the venturis and the spacer hol...

I was told the reason why the Gen 3 HEMI has a 114 lsa is because the motor is EFI...and EFI compensates for the negatives of a wide LSA - Does that sound reasonable?

Could I assume that 'narrowing the power band' is the same as lowering the peak hp rpm?
