Main Engine Block with Oil Fitting

Description

Main Engine Block with Oil Fitting

1/25 Scale Asphalt Modified

A precision‑printed small‑block engine foundation featuring an integrated oil‑fitting boss, 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, with added detail for oil‑system plumbing commonly used in Asphalt Modified competition engines.

The block is 3D printed on Elegoo Mars 3 Pro–series resin printers using high‑resolution settings to capture the casting texture, deck surfaces, oil‑fitting geometry, and mounting faces. 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 Typical Geometry & Your Product Photo)

The Main Engine Block with Oil Fitting features realistic small‑block architecture and added oil‑system detail, including:

• Accurate Small‑Block Proportions Correct deck height, cylinder spacing, and block width that visually match full‑scale racing small‑block engines used in Modified competition.
• Defined Cylinder Bank Geometry Both banks feature clean, sharp edges with proper V‑angle representation. Cylinder openings are printed with crisp circular profiles and realistic depth.
• Integrated Oil Fitting Boss The added oil‑fitting detail is printed cleanly with proper scale thickness and a defined mounting pocket. This feature replicates the external oil‑system plumbing used on high‑performance race engines.
• Crisp Deck Surfaces Flat, well‑defined deck surfaces provide 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.

What You Receive

A clean, crisp, paint‑ready Main Engine Block with Oil Fitting that provides the perfect foundation for any 1/25 Asphalt Modified engine build requiring external oil‑system detail.
