Guest Anonymous Posted August 6, 2002 Share Posted August 6, 2002 My boyfriend just built a 406 SBC for his '76 280z, wonder what you guys make of his combo? its 11.5:1 compression, hyperutectic flat tops, regular 400 rods , but with arp bolts, balanced with fluiddampener street dampener, motown 220 heads 2.05/1.625 valves with pocket porting, comp Xe 268 mechanical roller/ 236/242 @ .050, .567/.574 lift, preformer rpm airgap, 750 speed demon, and S&S 1 3/4 headers, comp promag rockers, and MSD digital 6. kinda curious if combo sounds tough enough to go high 10s? any feedback would be appreciated.

Guest Anonymous Posted August 6, 2002 Share Posted August 6, 2002 Hey where ya at in texas?? Im in the central tex area about 40 minutes south of austin. Sounds like yall got some setup. franklin Quote Link to comment Share on other sites More sharing options...
labrat Posted August 6, 2002 Share Posted August 6, 2002 DAMN! I ran that combo in DD2K, and it looks like about 500HP@5500 rpm and 535TQ@4000 rpm. If you can hook that beast (you didn't say exactly what car it's in, a Z?), it should get you at least close... Also, I second that, where are you in texas? I'm in north austin myself. I'd love to get a look at that thing running. my $.02 Bill Quote Link to comment Share on other sites More sharing options...

JoeinCA Posted August 6, 2002 Share Posted August 6, 2002 actually i think she said a 76' 280Z.... That engine combo should make for a wild car.. I think that getting into the high 10's with that car depends alot on your gearing. 500 hp in an approx. 2900lb car, should be pretty close to 10 sec 1/4 mile... right?

Guest Anonymous Posted August 7, 2002 Share Posted August 7, 2002 Absolutely, but you might want to get friendly with the driveline shop and have a few extra halfshafts on hand, you'll need them if you hook it up and break out the hi-test gas with that bruiser, I think at 11.5-1 it'll need it.

pparaska Posted August 8, 2002 Share Posted August 8, 2002 Sweet motor! BTW, I have the solid flat tappet version of that cam (PN 12-677-4) in my little 327 (9.7:1 compression) and it's just on the edge of what I'd call streetable - any more and it would be too much. I'd think it'd seem a bit more docile in a 383, and with that much compression even more so. I think you could easily go for a bigger cam if this is a drag-mostly car.

labrat Posted August 8, 2002 Share Posted August 8, 2002 Last I heard, the ricers hang out at fuddruckers up here. Well, they're not all ricers, I guess. Couple of camaros and stangs in there. If you want to hook up with some street races, check www.texasracingscene.com. they have a forum for Austin racing. Sometimes they hit zilker park, and sometimes they hang at northcross mall. depends on the night, but they get together several nights a week.
