Subject: Re: Engine swap on the C1 by wesmigletz on 2008/11/14 22:27:30 Bogus, we'll see. I have a finely calibrated SOTP meter. If I can make it to the track on the 22nd, we'll have definitive proof one way or the other. I'm in the 12s already, using the original #s matching (threw that out there for the NCRS types)block and heads. My heads were competition ported by Mike Stark at CFM performance, and I doubt much more could be gained from an OE Camel Hump head. I doubt the Darts will be that big of an improvement. I see the HR cam is the variable. It has less duration, but more lift. Both cams are on a 112* LS. That said, I don't expect to pick-up more than a couple of tenths. JSUP, I'm not a Dart hater. Given the 11 CC variance from spec, I would have to think that is a tooling issue. I suspect the heads are larger than 180 CC by design. Since the heads are CNC machined, the heads would not have that kind of variance as a result of machining. I didn't throw Dart down the stairs. I reported my situation with them. Simply put, the "part didn't match the print". It's not my job to do Dart's QC, and I have no interest in sending the heads back. They're finally going on my engine. As an aside, I'm friggin sick and tired of those making money off the automotive hobby not delivering what they claimed, thus my "you get what you pay for rant." Quite frankly, I do not believe that to be the case the majority of the time. It only applies when dealing with an honest person or entity. I'm a big fan of small, efficient, ports. The quality and volume of flow matter. This engine won't be dyno'd, but it will be taken to the track. My car is fairly well sorted, and the proof will be in the MPH on my slip. The heads/cam will deliver or they won't. It's not a direct A-B test, but I know exactly how the low-rent parts performed, and that will serve as a comparative basis. WRT, the ring issue, if the rings do not seal that would cause issues regardless of the head on top, be they new rings mis-matched to a cylinder's finish, or worn rings. |
