Need some guidance on building a 600+ horse Eagle for my Duster since my 410 LA engine is dead and gone. Starting with a complete 09 5.7 I traded small block parts for. Have TTI headers, MSD ignition, Manley 392 stroker kit, and various swap parts since it was already in another A-body. Going to send the heads off to a friend of mine in Idaho to have them opened up as much as possible, new springs and whatever else needs done. Need to buy a single plane carb intake and choose a cam to get me where I want to be.
I wanted to try to make it to 600 on pump gas, but may not be possible according to others I’ve talked to. Going with the carb setup so I can swap gas and methanol carbs for occasional street driving and racing on alcohol. It’s going to be 90% drag strip use, so pulling timing to cruise the street is no big deal especially at my 5000’+ altitude. I don’t know how forgiving the modern Hemi heads are for detonation.
I do need some direction on building this. The pistons I have are advertised at 12.5:1 with the 65cc chambers and .040” gasket. I’m not married to those pistons as they came with the used stroker crank and rods. There’s lots of cams out there, but doesn’t seem to be a lot off the shelf that’ll be aggressive enough. I did see Summit has some big ones available if they are decent quality. I’ll be using a 727, roughly 4500 stall and 4.10s.
My goal is run right around the 10.0-10.1 ET at sea level with a 3000# car. Don’t want to break into the 9s and deal with putting a cage in the car that needs certification every couple years. The best I ran with the 410 was 10.68 in those conditions.
