Ram Jet 454 For Sale - Updated 2/1/2010 We've been prototyping our 24x and 58x systems for the Gen VI BBC engines with this 1999 7.4L engine. When our prototyping is finished (March 2010), this engine will be available for sale. The Ram Jet 502 engine, while more powerful, does not include a desirable engine controller, does not offer coil per cylinder ignition, does not offer electronic transmission support, does not offer electronic (drive-by-wire) throttle, and is not tunable with popular tuning software (like EFILive or HP Tuners). Electronically, our 7.4L Ram Jet engine is state-of-the-art and offers much more than any GM crate engine. VIDEO: http://www.eficonnection.com/RamJet454/58xRamJet454.wmv What's the value? In comparison, GM sells the Ram Jet intake manifold, injectors, distributor, harness, and electronics under part number 12499249 for about $4,000 (street price).

Our old shopping site doesn't integrate well into this new design, but not to worry, all of the items you have previously been able to purchase through our website are still available using the navigation on the left of this page. You will be redirected to our old website to shop. For the best experience, this website is best viewed with Internet Explorer with JavaScript enabled. We receive many phone calls and email asking for clarification and more information about our 24x system and upcoming 58x system. This website has been updated to provide more information about these systems and content to address the most frequently asked questions. Don't miss the "Quote Your System" link on the left of this page to get an idea of the conversion costs and options for your SBC, BBC, or LT1. We thank you for your continued support, business, and patience while we transition to our new website.
