We have a new motor that we are working on that is based off of the 5.7 block. The motor is bored and stroked to 413ci for the maximum in hp/tq for your 5.7. The motor is being designed for NA applications and maintains a cylinder wall thickness identical to our 6.1 stroker combinations.
NA Compression Ratios
10:1 using 03-08 heads (Ideal truck motor)
10.5:1-11:1 using 6.1 heads (Ideal 93 octane NA motor)
11.3:1-12.3:1 using eagle heads (Ideal for 93 octane NA motor)
Boosted Compression Ratios
8.8:1 using 03-08 heads (12-15psi capable)
9.75:1 using 6.1 heads (10-12psi capable)
10.3:1 using eagle heads (up to 10psi capable)
For different compression ratios, we can order a custom piston to suit your needs. This motor is really at home as an NA engine.
413ci Longblock: $7000 (No Core Charge) Only 1 at this price
Comes standard with Manley crank, rods, and pistons. Iron rings, clevite bearings, camshaft, timing chain, lifters, forged pushrods, eagle mean street heads, cometic head gaskets, and factory main/head bolts.
In an 09-10 5.7 vehicle, power output is estimated to be 450rwhp/475rwtq due to camshaft and rpm limitations.
In any non-VVT platform, we are shooting for 500rwhp/500rwtq.
These estimates are based on a ported 6.1 intake, 90mm tb, longtube headers, free-flowing exhaust, and a custom tune.
Available options include the following.
Tool Steel wrist pins: Boosted/N2O
ARP Main/Head Studs: Boosted/N2O
Pro-Series I-Beam Rods: Boosted/N2O
Coated Pistons: Boosted/N2O
Steel Rings: Boosted/N2O
Gapless Rings: Boosted and NA applications
Ported 6.1 Intake
Longtube Headers
90mm or 100mm Throttle Body
