Congrats on the article... I always see your sig listing the DRM mods but wasnt until reading the article that I missed a detail... like that you are still using stock valves on the heads! Is that what is usually considered Stage I when you retain the stock valves?
For DRM to make over 400rwhp with stock valves is quite impressive. Usually, people posting those kind of numbers go Stage II with bigger valves.
Also, since they are CNC'd, if anyone were to goto DRM for the same head work done, the CNC machine would basically make a copy of the ones that are on your heads eh? Do you have flow numbers from DRM on the heads?
I ask cause my wife has hinted giving me a green light on making a trip to Texas (can you say MTI?) for sometime next year but I'm keeping my options open. Lingenfelter's ASA-spec LS6 heads sound interesting and Dave Farmer says they also use stock valves.
Thanks everyone! Susan got a kick out of it when I showed it to her last night. Gee, that didn't sound right. Thanks especially to JC and the moderators for picking our Z06 to feature first. :cheers:
Don, I didn't write the flow numbers down for the heads, but I remember Doug telling me they were real happy with them. I think Doug could give you the details and that he could duplicate them. We did a stage 1 package for cost reasons and because I road race and a high peak hp number isn't as important as a flat torque curve and power building to redline. The car pulls hard and I think the trap speed I got of 120.95 could have been higher, but I shifted to 4th too early (about 6200 rpms) for some dumb reason. Next time, I would shift a redline and I think a 123 mph trap is possible running these stock valves.
Congratulations Susan and Ron!!! :cheers: Not only do they have a great looking car, but they are two of the nicest people I know. :yeadog: Ron has helped both my husband and me do various mods and work on our Vettes. They are so much fun to go cruising with, race with and do a few third gear pulls against. Our road trips with them are never boring. Our unofficial club, The Minnesota Renegades, uses Ron's motto, "Drive it like you stole it" on our shirts and he does! After riding with me around the race course in Joliet, one of the nicest things my husband ever said to me was, "JC, you drive like Ron Marks!" :lol:
