C5R 427ci 7 Liter
C5R 427ci 7 Liter
Was refreshed by Doug Rippie Motorsports in the fall of 07'. Has ~5500 miles on it now 11.8:1 cr. As with any other built large cube motor, it eats oil. i'd say 1 qt every 1k miles. road racing and drag racing, it eats a lil more. After any race event, i always change oil. i use Redline full 10w30 synthetic. The motor made 520rwhp thru unlocked converter and closed cutouts. Cutouts open typically gave me 21rwhp and 12rwtq gain. So its a pretty potent motor. The motor will be a drop in for any C5 corvette. For a C6, it will require some adapter harnesses that run about $300. Can be a drop in fit in any f-body (TA, Firebird, Camaro) I also have available at an extra cost: 90mm FAST intake 90mm Nick Williams Throttle Body Vararam Intake System Kooks 1 7/8" LT headers Kooks 3" x-pipe with mid section DRM oil cooler kit Here are the specs that i know: LS6 243 heads bored out as far as they can be. flow 330cfm @ .614 -Ferrea severe duty 1 piece ss valves -isky 6205 double valve springs -titanium retainers -bronze valve guides comp cam lift: .630 duration: 244 lsa: 112 Lunati forged steel 4.00 crank ALL ARP hardware (rods/head bolts) ATI super dampner, pinned Lunati billet steel rods 6.125" Wiseco 11.25:1 forged aluminum pistions 4.125" diameter childs&albert plasma moly rings clevite bearings Leak down data also available I am asking $11K for this setup. It has cost around 30K to built. This motor was built as a strong N/A setup. The power is always there, on tap and ready to roll. DRM can send this out to buyer on a crate/pallet. Thanks for viewing. will get pics up asap |
