I'm thinking about building a 408 for my duster. My question is are there anyone run low 11 on the motor and 9s on the spary? If so would you post your specs or what can I build to make this happen? Gear and converter as well.
Ok if I wanted a real simple 10 second street car and couldn’t port my heads this is what I would do with a 408
408 (10.5-10.8 comp)
Set of out of the box ProMaxx heads that have been checked out as I check everything out
Call Jim at Racer Brown and order one of his .520 lift solid cams
Port matched and plenum radiused Victor340 intake
MSD distributor
750-850 Holly carb
904 or 727 Transmission
4.10 gears
And as much convertor as you are willing to go with (yes high stalls are streetable) with a good cooler.
BP93 pump gas or equivalent
If that doesn’t get you in the low 11’s or 10’s with a 408 in a 3200 pound or lighter car something is wrong
