It should have similar potential to Dusty's combination.
So I am thinking maybe 5.2-5-3 in the 1/8 and 7.9 - 8.2 in the 1/4.
I am not sure if LL want s to play that hard but the combination will have that ability.
To be honest the turbo is ready for that chassis to be in the 4.8/7.4 range but the heads will be a restriction long before the turbo can make that power.
Just an update . I started on the headers yesterday. This is the drivers side. The pass is going to be a duplicate. They are mild steel 1 3/4. The crossover is going to be 3 inch dia.
I have also ordered a PTC converter and powerglide thru Dusty.
John, I doubt that Ill run Orlando. I have been reassigned at work so the time to finish the car is not gonna be there. I have redirected my anger at these headers. I dont think I would have made them so fast otherwise. So far i have about 20 hrs in them. I have tigged about 40% of tubes and flanges.
