Thanks for the info, the intake will have to stay, for hood clearance.raceczar wrote:The stock intake is J-U-N-K.
The 509 cam is prolly the best street cam they had. That 528 was on 122 LSA IIRC. I would skip that thing.
At 383 inches it will need to idle at about 12-1300 MINIMUM...1500 will prolly be better.
If you can deal with the idle set there, disconnect the tach.
So, IMHO, ditch the intake and carb. A 750 DP and a single plane intake would be better. A 3.90 gear is about as tall as I would go. With a 2.66 1st gear you may get away with 3.73's. 4.10 would be bitchin'.
Tune from there.
Im not sure what you mean by "that 528" ?
Since I made the tweaks that I did, it does idle great @ 850, I just dont think it should need 32* advance to do it and still only pull 5" vacuum....something is fubar, I will spend sometime next week checking things out more thorough.
I would like to see a DP with 4 corner idle as well, it may get that before this is over.
As far as gearing.....it is what is is at this point.
