will my D1sc work with this set up? Hey guys... As we speak I am having a 427 superdeck I built at ERL, and after buying all the supporting mods my budget is limited. I have a D1sc on my stock bottom ls1 trans am right now, would it be worth putting the D1 on the 427 and running it with that till I can save for a F1? Anyone think I can make descent power with the D1 if I come close to maxing it out? My setup is pushing 553 RWHP right now. Can I at least surpass that with the smaller blower? Or should I not install new motor till I can afford a new F1? Would eventually like to hit 750-850 whp... then push it more later with proper blower.

Any guesses of what max boost would be from the D1 with good flowing heads and exhaust? I'm looking at the LSX-LS9 heads with a good CNC port job with 1-7/8 or 2" step headers.

Yes, I would upgrade to a better bracket as well. Belt slippage becomes a bitch when you swap to a smaller pulley and try to make some big power with that blower.
Hard to guess max boost. Max boost is irrelevant anyways since, as stated earlier, a nice free flowing motor with big cubes would make less boost than a smaller less efficient setup but the overall power output would likely be greater.

get the aster bracket and water pump needed from bob at brutespeed.
Then you could get the cbm 8.xx crank pulley , run a 3.4 and max the d1 out .
Aster is the best and newest bracket for the fbodies .

Well, there's a video out there of Steve Morris running a D1SC on a 540 big block chevy and made north of 1000 dyno hp. So figure in drivetrain loss, and you're looking at 800 or more rwhp. Lot's of guys are making north of 800 with a D1SC. You're going to make more torque than a smaller cube motor, so that's a plus.

Great post as I am starting my research and will be in the same situation.
Why do some members choose to go with a smaller displacement engine, I see many in the 390 to 404 range. Is this because they are turbo guys and the engine displacement and turbo sizing goes hand in hand?
Since I don't plan on going turbo wouldn't I want to get as much displacement as possible? Right now I am looking at ERL or Mast with displacements in the 427 to 440 range.
In my case my goal is to have as much performance as possible but not have to worry about durability. So my thinking is go with as much displacement as possible and since my D1SC doesn't change I will be running less boost due to the larger displacement but yet still have a very big increase in hp due to the displacement increase. And since the engine will have max boost less than what a 347 would have given same pullies I wont have to do anything like Meth to keep the engine together.
In a nut shell what would be the case to get a 390, 404, 414 over the larger 427 and 440 offerings?

I have read that too and it seems common that most applications are not greater than 4" stroke so makes sense. The most 440 is a 4" stroke so I would be OK if I went the mast route and 440. I like ERL ALOT so still thinking about there offerings as well.
Tough decision and a lot of research is still needed.
