A properly manufactured and maintained\n          block can last for the service life of the engine. Overheating, poor\n          lubrication, corrosion, detonation, contamination and incorrect\n          assembly shorten its life.\n        <\/p>\n      <\/details>\n\n      <details>\n        <summary>\n          How expensive is it to fix an engine block?\n          <b>+<\/b>\n        <\/summary>\n\n        <p>\n          Cost depends on damage, engine design and required operations. Honing\n          or resurfacing costs less than installing liners, repairing cracks,\n          rebuilding the rotating assembly or replacing the engine. Inspection\n          is required before a reliable quotation.\n        <\/p>\n      <\/details>\n\n      <details>\n        <summary>\n          What is the strongest material for an engine block?\n          <b>+<\/b>\n        <\/summary>\n\n        <p>\n          There is no single best material. CGI and ductile iron provide high\n          strength and stiffness; gray iron offers wear resistance and damping;\n          reinforced aluminum provides a better strength-to-weight ratio.\n          Selection depends on pressure, temperature, weight, bore design and\n          cost.\n        <\/p>\n      <\/details>\n    <\/div>\n  <\/div>\n<\/section>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c5e5627 elementor-widget elementor-widget-html\" data-id=\"c5e5627\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"html.default\">\n\t\t\t\t\t<!-- Custom Engine Block Final CTA | Standalone Elementor HTML block -->\n<style>\n  #web-engine-cta-01,\n  #web-engine-cta-01 * {\n    box-sizing: border-box;\n  }\n\n  #web-engine-cta-01 {\n    --webcta-primary: #2d2f91;\n    --webcta-primary-deep: #24266f;\n    --webcta-accent: #55b9cf;\n    --webcta-ink: #243b46;\n    --webcta-muted: #5f7783;\n    --webcta-line: #c9e2ee;\n    width: 100%;\n    padding: 64px 0;\n    border-top: 1px solid var(--webcta-line);\n    background: linear-gradient(120deg, #eaf6fc 0%, #f5fbfe 62%, #fff 100%);\n    color: var(--webcta-ink);\n    font-family: Arial, Helvetica, sans-serif;\n  }\n\n  #web-engine-cta-01 .webcta-container {\n    display: grid;\n    grid-template-columns: minmax(0, 1fr) auto;\n    align-items: center;\n    gap: 70px;\n    width: min(1180px, calc(100% - 40px));\n    margin: 0 auto;\n  }\n\n  #web-engine-cta-01 .webcta-copy {\n    max-width: 780px;\n  }\n\n  #web-engine-cta-01 .webcta-eyebrow {\n    margin: 0;\n    color: var(--webcta-primary);\n    font-size: 14px;\n    font-weight: 800;\n    line-height: 1.35;\n    letter-spacing: .12em;\n    text-transform: uppercase;\n  }\n\n  #web-engine-cta-01 h2 {\n    margin: 12px 0 0;\n    color: var(--webcta-ink);\n    font-size: clamp(29px, 3.2vw, 35px);\n    font-weight: 800;\n    line-height: 1.18;\n    letter-spacing: -.025em;\n  }\n\n  #web-engine-cta-01 .webcta-description {\n    margin: 15px 0 0;\n    color: var(--webcta-muted);\n    font-size: 16px;\n    line-height: 1.72;\n  }\n\n  #web-engine-cta-01 .webcta-button,\n  #web-engine-cta-01 .webcta-button:link,\n  #web-engine-cta-01 .webcta-button:visited {\n    display: inline-flex;\n    min-height: 48px;\n    flex-shrink: 0;\n    align-items: center;\n    justify-content: center;\n    border: 1px solid var(--webcta-primary) !important;\n    border-radius: 9px;\n    padding: 13px 20px;\n    background: var(--webcta-primary) !important;\n    color: #fff !important;\n    font-size: 15px;\n    font-weight: 800;\n    line-height: 1.3;\n    text-align: center;\n    text-decoration: none !important;\n    box-shadow: 0 10px 24px rgba(45, 47, 145, .16);\n    transition: background-color .18s ease, border-color .18s ease, transform .18s ease;\n  }\n\n  #web-engine-cta-01 .webcta-button:hover,\n  #web-engine-cta-01 .webcta-button:focus,\n  #web-engine-cta-01 .webcta-button:focus-visible,\n  #web-engine-cta-01 .webcta-button:active {\n    border-color: var(--webcta-primary-deep) !important;\n    outline: none;\n    background: var(--webcta-primary-deep) !important;\n    color: #fff !important;\n    text-decoration: none !important;\n    transform: translateY(-1px);\n  }\n\n  #web-engine-cta-01 .webcta-button:focus-visible {\n    box-shadow: 0 0 0 4px rgba(85, 185, 207, .25);\n  }\n\n  @media (max-width: 760px) {\n    #web-engine-cta-01 {\n      padding: 52px 0;\n    }\n\n    #web-engine-cta-01 .webcta-container {\n      grid-template-columns: 1fr;\n      gap: 27px;\n      width: min(100% - 28px, 1180px);\n    }\n\n    #web-engine-cta-01 h2 {\n      font-size: 28px;\n    }\n\n    #web-engine-cta-01 .webcta-description {\n      font-size: 15px;\n    }\n\n    #web-engine-cta-01 .webcta-button {\n      width: 100%;\n      min-height: 50px;\n    }\n  }\n\n  @media (max-width: 430px) {\n    #web-engine-cta-01 .webcta-eyebrow {\n      font-size: 12px;\n    }\n\n    #web-engine-cta-01 h2 {\n      font-size: 26px;\n    }\n  }\n\n  @media (prefers-reduced-motion: reduce) {\n    #web-engine-cta-01 .webcta-button {\n      transition: none;\n    }\n  }\n<\/style>\n\n<section id=\"web-engine-cta-01\" aria-labelledby=\"webcta-title\">\n  <div class=\"webcta-container\">\n    <div class=\"webcta-copy\">\n      <p class=\"webcta-eyebrow\">Engineering Review &amp; Quote<\/p>\n\n      <h2 id=\"webcta-title\">Start Your Custom Engine Block Project<\/h2>\n\n      <p class=\"webcta-description\">\n        Send your drawing or model with the blank condition, material, quantity,\n        bore requirements, tolerances and inspection specifications.
