Introducing the Inertia 5.7/400 CID for $4495

Inertia is offering an introductory special on the Inertia 5.7 based 400 CI engine for a base price of $4495 with block exchange.

That includes premium CP pistons that laser etched in superior strength 2618 alloy with the inertia 400 logo, Forged crank, forged H beam rods with ARP bolts, premium rings 1.2/1.2/3.0 mm gas nitrided top and napier second rings for minimal friction, maximum strength and heat resistance yet excellent oil control in a lightweight rotating assembly for outstanding throttle response. the 400 can be ordered in about any compression ratio desired.

This isn't the budget stroker package that others are selling for similar prices. that are built with the cheapest forged components available. This engine is built with superior components and superior attention to detail that you don't get from the kit motors.

 

That`s a GREAT price!!!!! How much Horse Stu?

 

Jason/USCG Charger's 5.7 based 383 Inertia stroker is putting out 450 RWHP after his tune so this one should be in the ballpark, maybe a little bit higher.

 

depending on cam, heads and other associated components I'd say anywhere from 400 to over 500 RWHP

 

wait your going to make over 500rwhp from a 400? when the 426 guys are barley doing it? I am not saying you cant stu you know your shit 10000000X times more than I will ever know but I dont see 500HP to the wheels

 

The cubes don't make much difference between 400 and 426 it's all in the heads, cam, intake and associated parts. There is really not 10 HP difference between a 400 and a 426 if everything else is equal.

The point is if you build one with 13.5 CR, gas port the pistons, run a big cam with big valve heads, port the intake and run a dual TB and tune it right and everything around it is up to the task your going to go decently past 500 RWHP. If you set it up with stock 5.7 heads and intake and a comp 268 cam you'd be pressed to get 400 RWHP. There is power in a short block from things like light rings, piston design, friction reduction, light rotating assemblies, knife edged cranks, reduced windage,,,,, but the short block is primarily there to hold up to what the other parts are going to throw at it and last and do it as efficiently as possible. The benefits from reducing parasitic power losses and increased efficiency better geometry,,, from a superior short block are there but relatively small compared to other items.
