Heavily built, C5R 427ci 7 liter will be up for sale.
was just refreshed by Doug Rippie himself in the fall of 07'. Has ~5500 miles on it now. 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.
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
side note, i have a nitrous kit on the car but i have only sprayed a 100 shot seven times thru motor. A/f ratio was dead on at 11.6:1 so it was still rich and safe. not even a full bottle thru this thing.
At this point, i will NOT part out to make it a short block. It will go out only as a long block. If it does not sell, no worries, i am keeping for a future GTM built.
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. My for car sale ad has a dyno sheet on it showing the power curve. Again, DRM can send this out to buyer on a crate/pallet.
Thanks for viewing.
