The experts at Hooker BlackHeart have taken away the guesswork of where to position your engine swap and we've followed up on our popular GM G-Body LS line with a new version that allows you to choose LS or LT engines by utilizing 4th Gen F-Body clamshell engine mounts.  To complete the engine mounting be sure to follow these steps:\n\n1). Choose the proper clamshell for your engine:\nGen III\/IV (LS) - 71221018HKR\nGen V (LT) - 71221019HKR\n\n2). Add the thru bolt kit:\nGM LS\/LT\/Gen III Hemi - 71223015HKR\n\n3). Choose the polyurethane insert in the color you prefer:\nBlack - 71221016HKR\nRed  -  71221017HKR\n\n\nFor the transmission, this kit is designed to be used with the same G-Body transmission crossmember already in production (12644HKR-1) for a trouble-free installation and optimized driveline angles.  This system is compatible with almost any popular GM transmission, even modern 6-speed, 8-speed, and 10-speed applications. An adapter kit may be necessary for applications that were NOT equipped with a 200-4R transmission from the factory - Part # 12647HKR.\n\n12644HKR-1 - Transmission Crossmember (no additional adapter needed for TH400\/200R4\/T-56\/Magnum)\n12655HKR - 4L60\/65\/70\/75 Transmission Adapter - use with 12644HKR-1\n12656HKR - 4L80\/85 Transmission Adapter - use with 12644HKR-1\nBHS5181 - 10L80\/10L90 Car Transmission Adapter - must be used with both BHS5182 and 12644HKR-1\nBHS5182 - 6L80\/90, 8L45\/80\/90, 10L80\/90 Transmission Adapter - use with 12644HKR-1\nBHS5183 - Tremec TKX 5-Speed Transmission Adapter - use with 12644HKR-1\n\n*For installing a 10-speed GM car transmission, both BHS5181 and BHS5182 will be used together to achieve the proper spacing and alignment.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eWhen coupled with the Hooker BlackHeart transmission crossmembers 12644HKR-1, these mounting brackets locate the engine in the same nominal position (fore-aft, height, offset, etc.) as the original engine\u003c\/li\u003e\n\u003cli\u003eEasily switch between LS and LT engines through a simple change of the necessary 4th Gen F-body clamshell engine mounts: 71221018HKR for LS and 71221019HKR for LT.
