Engine Block

Description

Engine Block

1/25 Scale Asphalt Modified

A precision‑printed small‑block engine foundation designed for builders who want accurate core engine geometry, crisp casting detail, and a paint‑ready finish straight out of the package. This block replicates the proportions and structure of a full‑scale racing small‑block, making it the perfect starting point for any Asphalt Modified engine build.

The block is 3D printed on Elegoo Mars 3 Pro–series resin printers using high‑resolution settings to capture the casting texture, deck surfaces, and mounting geometry. Supports are generated in CHITUBOX Software to ensure stability during printing while keeping cleanup minimal.

Every part is cleaned with degreaser and 91% isopropyl alcohol, fully cured, and delivered ready for primer and paint.

Detailed Description (Based on the Photo)

The Engine Block features realistic small‑block geometry and casting detail, including:

• Accurate Small‑Block Proportions The photo shows correct deck height, cylinder spacing, and block width, matching the architecture of real racing small‑block engines used in Modified competition.
• Defined Cylinder Bank Geometry Both banks feature clean, sharp edges with proper V‑angle representation. The cylinder openings are printed with crisp circular profiles and realistic depth.
• Crisp Deck Surfaces The deck surfaces are flat and well‑defined, providing a clean mounting interface for Hurd Hobbies cylinder heads, intake manifolds, and accessory components.
• Realistic Casting Texture Subtle casting‑style contouring across the outer surfaces mimics the look of aluminum or iron performance blocks. Smooth enough for paint — textured enough for realism.
• Front & Rear Mounting Geometry The front face includes accessory‑mount contours, while the rear face aligns visually with bell housings and transmission assemblies.
• Clean Resin Finish No warping, ripples, or distortion — the block prints smooth and uniform, ideal for metallic paints, washes, and weathering.

This engine block integrates seamlessly with Hurd Hobbies cylinder heads, manifolds, carburetors, pulleys, ignition components, and full driveline kits.

Key Features

• Ready to Paint: Fully cleaned, cured, and prepped for primer.
• Professional Resin Workflow: Degreased and rinsed with 91% IPA for a residue‑free finish.
• High‑Detail Printing: Produced on Elegoo Mars 3 Pro (and Mars‑series equivalents) for crisp edges and smooth transitions.
• Optimized Support Strategy: CHITUBOX‑generated supports minimize sanding and preserve fine structural details.
• True‑to‑Scale Geometry: Designed specifically for 1/25 Asphalt Modified builds — SMART Tour, Whelen Modified, and similar chassis styles.
