no need for any more compression with that much cubic inches and twin gt42's...they will light off great especially with those good heads......I bet that bullet would actually spec out something even larger....20 psi on that motor and those turbos should make 1300+ hp......
I had the same basic turbos on my indy headed 408 small block and they lit of pretty good...

The goal is to have a street car that can run NHRA SuperComp with only a change of tires. 1300-1500hp is about what I am looking at. The car should be able to attain a low 8 sec run, but I really don't feel the need to run that fast. I am building the cage to 7.50 spec, but leaving out the funny car cage so I don't have quite the jungle gym to climb out of at the local diner. So it will be cert'ed for 8.50. It is a car that will be driven more than raced. but I spend a fair amount of time at the track. I am hoping for about 165-170mph in the 1/4 mile. I plan on using BOV's to control boost on the launch and act as the "throttle stop".

IMO, Good baseline Cam getting started. .642/.657 254* Intake / 248* Exhaust @ .050" Installed 110* 114 Lsa
The shorter exhaust duration gives higher pressure. You will need a tighter convertor. Target 140 psi on the Cranking Pressure with about a 66-68 intake closing ABDC.
Better to be a "has been" than a "never was".

Heres the cam i choice for a similar build 470cid 440-1 heads,single turbo going in a 62 valiant You may need a to think about that gearing turbos like to be held back some you may want to think about 2.94 or 3.23 Just my 2 cents Aaron

"I am hoping for about 165-170mph in the 1/4 mile. I plan on using BOV's to control boost on the launch and act as the "throttle stop"."
BOV's dont control boost nor will they act like a throttle stop. they are already open when you are off the throttle releasing access boosted air. Those would be wastgates. And if your looking to get involved as what you are talking i would invest in a good boost controller like AMS500 or 1000 or boost leash.
X2 on the gearing suggestion.

I have the ams500 with co2 in the valiant now and its money well spent..Also its the waste gate that controls boost the Bov is for releasing the boost when the motor goes into a vacuum state like when you let up on the throttle.. Also i control timing with msd6al 2 program able and a lock dizzy
