| Heads and Cam are in! Problems |
Subject: Heads and Cam are in! Problems by Anonymous on 2006/2/5 16:12:53 Im using a custo grind cam and full cnc ported heads. 93 stock bottom with 3.73 and 2400stall. New 30 svo inj, 52 tb, vented opti, and new LT4 timming chain. Started out with 275 hp and 300TQ The new dyno results are 327 hp and 322 TQ. The graph shows a hp peak at 5600 then all of a sudden both hp and TQ go straiht line down. Something is happening here. Car runs way rich at WOT in the beginning, bogs a little before it pulls and cleans out. Theres tunning issues here obviously. Im short at least 20 hp and TQ . Talking with installer says it felt like a rev limiter. My tunner said rev limiter set at 6400 and thinks it could be a valve train issue. The installer said new pushrods where needed so he changed them. Is it possible he should of left my 7200 Manley pushrods in there? What do you guys think about all this. The cam should make a little more power then tipical hot cam but it has a nice lope idle with a 110 LSA. |
