Alright so just just got my 408 stroker block in from Faust performance pushing 610hp gonna and twin 74mm should make about 1500hp what I was told want to know what fuel pump oil pump and I fuel injectors to run for this build

If you are asking these questions, how do you know it makes 610 hp now? Certainly the engine builder got you set up with the right oil pump for the combination......right???

I have a feeling that 1500 hp from a 4 bolt ls deal is not what you think. What did you have in mind for fuel type?

I would be more interested to know what cam it has in it, and what static and dynamic compression ratios are. This will affect how you go about adding nearly 150% output power to an existing engine. Twin 74s on a 408 could make north of 1500hp. The question is will it happily do it and for how long. I have a little 365" that I am putting twin 69s on and plan to make 1500hp. I just built it for that tho. I will never know what it would make n/a

He did dyno on motor and I didn't ask him yet and about pump or any of that
And E85

Are you running E85 or? Holley just came out with an ultra dominator dual fuel pump. There's a couple different versions but it's pretty new and e85 capable. I called Holley and talked to them and also my tuner, Mike Norris, highly recommended it over many others. I'm running E85 so I needed the extra flow capacity for the switch. I believe E85 burns about 30% more fuel. As for injectors I just purchased Injector Dynamics ID1300s. You could email them directly to see what you would need. Probably 1500s or 2000s depending on your fuel choice. But they're customer service is awesome. Emailed me back almost right after I emailed them. Anyways, hope this helps a little.

Dude built, and you are anticipating that he is going to keep the oil pump.

The Holley Dominator pumps suck ****.

Really? Please elaborate. I'm all about new info and don't want to give bad advice. I have not ran the Holley pump yet. I actually bought an Aeromotive and everyone told me they get way too hot and Aeromotive themselves told me to run a fuel cooler with a fan on the return line. So I returned it. Holley had the best reviews from the different shops that I trust. This pump was just released May 6 so it's a brand new style as well.

I have never had any luck with the Holley pumps either. And just so you know. Anything made by Holley is China crap. I have used Aeromotive pumps for years with zero problems. Lots of people use Magna Fuel. I have not. But they are rated as one of the best.

What oil pump and injectors did the builder use? Did he take the pump back out?
Tell us more about the build.

Yeah, I think we are all trying to figure out the "oil pump" question.

I assume op means high volume vs high pressure. Or possibly if dry sump is required? In my case, I went with a melling high volume and ported it. Dry sump is better but $$$

Agreed

OP, your best bet is a belt drive fuel pump if your trying to crack the 1500 rwhp barrier on e85. Is the main goal here to go to dyno meets and it be a dyno queen, if so you may not have too steep of a learning curve (parts breakage along the way). If you are trying to build a drag car for 1/4 mile racing at 1500 rwhp.......you're not gonna have too much fun. It takes a pretty serious 4 bolt ls to do that reliably.
