While the 1970 Chevelle SS 454 LS6 does get the limelight, the Camaro wasn&#8217;t forgotten by Chevrolet. From the high-revving 302 Z\/28 and big-block 396 SS of the late \u201960s to the solid-lifter LT-1 small-blocks of the early \u201970s, every generation delivered its own balance of power and personality. Understanding the original Camaro engine codes, casting numbers, and horsepower ratings is an important detail for collectors, restorers, and enthusiasts looking to verify authenticity or plan a period-correct build. Even for those who aren&#8217;t planning a period correct build, it&#8217;s always neat to see what was under the hood when your Camaro left the assembly line.\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-db685fc elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"db685fc\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-b92a2e2\" data-id=\"b92a2e2\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-3a24902 elementor-widget elementor-widget-heading\" data-id=\"3a24902\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">How To ID a V8 Camaro Engine<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f2b8c6a elementor-widget elementor-widget-image\" data-id=\"f2b8c6a\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"620\" height=\"413\" src=\"https:\/\/www.ss396.com\/cars\/wp-content\/uploads\/2025\/10\/1967_chevrolet_camaro-ss_Pics-81.jpg\" class=\"attachment-large size-large wp-image-83217\" alt=\"\" srcset=\"https:\/\/www.ss396.com\/cars\/wp-content\/uploads\/2025\/10\/1967_chevrolet_camaro-ss_Pics-81.jpg 620w, https:\/\/www.ss396.com\/cars\/wp-content\/uploads\/2025\/10\/1967_chevrolet_camaro-ss_Pics-81-300x200.jpg 300w\" sizes=\"(max-width: 620px) 100vw, 620px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-e369abe elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"e369abe\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-8e2bd05\" data-id=\"8e2bd05\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-32f5674 elementor-widget elementor-widget-text-editor\" data-id=\"32f5674\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><strong>Engine pad stamp (a.k.a. suffix code):<\/strong> On the engine-blocks, look at the machined pad at the front, passenger side deck.<\/p><p><strong>Block casting number and date:<\/strong> Rear driver side of blocks near the bellhousing flange; Casting dates must pre-date the assembly stamp and vehicle build and are generally found on the passenger side.<\/p><p><strong>Where to decode:<\/strong> For 1967\u201369, the Camaro Research Group (CRG) lists all suffix codes, block castings, head castings, and production totals.
