Breeze77z Posted March 13, 2004 Share Posted March 13, 2004 I've been tossing around the idea of putting one in my '77 280. I've been researching, and i have a little experience from my Dakota R/T daily driver, however, I can't find an indisputable source concerning the stock compression ratio. My 250hp/345lb-ft R/T apparently only needs a bigger cam (PN-4876348), headers, and an M1 intake to match the Magnum 380hp/410lb-ft crate motor, IF...the CR is in fact 9:1. Also, I'm not sure about what tranny to use. I don't like autos, but the NV3500 5-speed they put behind the 318 and new 4.7L isn't strong enough to support the 360's torque (or so says krcperformance.com), which I can believe seeing as how dodge does not offer it behind the 360. And i'm confused by the description for part number: 5249842 at http://www.mopartsracing.com/parts/trans.html (4th down below flywheel pic). the part is a properly balanced flywheel for the magnum 360, but says it is for carb use only, why does that matter? thanks for any info. Patrick ps, sorry is this is a duplicate post, i tried once and it disappeared. Quote Link to comment Share on other sites More sharing options...
Greg55_99 Posted March 13, 2004 Share Posted March 13, 2004 Well, since there's no form of purity on this board, you could try the Toyota Supra Turbo R154 5-speed. I've never done it, but, it's possible to do! The Aussies use a custom bellhousing to pull it off, but, here in the States, the 94-00 Dakota 3.9L V6 bell does the same thing. It's uses a hydraulic clutch. I'm talking about the Supra Turbo box only. The non-turbo box is not the same. http://www.classicconversions.co.uk/r154.htm http://www.novak-adapt.com/knowledge/ax15.htm http://www.moparmarket.com/stories/supra.htm http://www.moparmarket.com/tech/archive18.htm http://www.autospeed.com/cms/article.html?...gestions&A=0260 Greg Quote Link to comment Share on other sites More sharing options...
Guest blown408 Posted April 13, 2004 Share Posted April 13, 2004 The 5.9 mopar is either 8.9:1 0r 9:1 depending on who you talk to or read. I'm thinking of putting the original 5.9l that came out of my r/t into my 82 280ZX. Can't find anyone who's done this yet, but i'd want a manual too. Was thinking about a t56 from kinsler.

zxgts-4 Posted April 14, 2004 Share Posted April 14, 2004 Hi Patrick Another option for manual trans is the Tremec TKO offerred in a kit by http://www.keislerauto.com. Neil Quote Link to comment Share on other sites More sharing options...
