TBI cam duration

[CSH-HQ]

Whoaa, stop, look listen, think,
read the archives, your way behind in your homework, way behind.
Your about three days hard ride behind the info available.
NO A STOCK CHIP AIN'T CLOSE
The stock 305 injectors won't support 280 HP
Use a BBC TB and forget the Holley
Start reading, and leave your ego+ideas at the door.
Try Cross fire 747 programming 101 for openers
then tuning.doc, and tuning.txt  from the FTP

  BTW, I run mid 13's granny style with tbi

>Build a 355 short-block, late model, deck-mill heads to get almost 10:1 CR.
>Port stock 350 late model heads, have them re-done with 300 lb springs and
>pins in the rocker studs
>Put that cam I mentioned (213/219 duration, 112/108 LC) roller, and add
>headers & 3" pipe.  THEN, I though hook-up my stock 305 TBI ('88 L03), see
>how the motor runs (if it idles, if it runs).  If it seems to run OK, then
>add the Holley throttle body (for a 5.7 motor, 670 cfm) and see how that
>goes. By this point I can drive the car and see some high-rpm pulls.  If
>still not sattisfied (need to watch money buy this point not to go into
