Are you going to go with 1.6 Roller Rockers as well? I don't know if you've done it already, but I would switch to a double roller as well...especially if the timing chain had anything to do with your bent valve.

nazar Posted September 28, 2006 Author Share Posted September 28, 2006 yea, 1.6 rockers, it will be closer to 600 lift im gettin dual roller chain as well valve bent because of a broken keeper i think...no damage though, just bent valve Quote Link to comment Share on other sites More sharing options...
80LS1T Posted September 28, 2006 Share Posted September 28, 2006 Do you have any head work done or aftermarket heads? I thought you said you had ported heads but I dont remember for sure? I am really looking forward to seeing the dyno results. I may end up with this cam also. How much was it for the cam and springs?

roller Posted September 29, 2006 Share Posted September 29, 2006 cam is way big. Quote Link to comment Share on other sites More sharing options...
nazar Posted September 30, 2006 Author Share Posted September 30, 2006 well the heads will be getting ported too, a local porter here who does wonders on v8 heads has done multiple lt1 heads and keeps giving me a better and better deal because he really wants to see a big head/cam 240z go , lol...he gave me a deal i couldnt refuse heads are getting ported, new ss valves, etc... I actually held off on the 847 cam to do something different and not as proven I am going with the new XFI based cam but a more custom grind from combination motorsports Its on a 111lsa, 233/239 duration and .569/.577 lift with 1.6 rockers I will be using beehive springs My heads that will flow mid 250s/180s hopefully will get me over 400whp , which is my goal I still need 30lb injectors. 400whp at 2550lb on slicks should HOPEFULLY get me low 11s if not the magical 10.99 on the motor which would be amazing Quote Link to comment Share on other sites More sharing options...
that240guy Posted September 30, 2006 Share Posted September 30, 2006 you are going to want more than 30 pound injectors if you are shooting for 400 whp. 36 or 42 would be best. 30 lb injectors will be over 100% duty cycle at 400 hp. 42 pound injector will be just less than 80% which is ideal.

nazar Posted September 30, 2006 Author Share Posted September 30, 2006 30lb injectors wont be enough? I am at 336whp now on stock 24lb injectors at about 86% or so i think, with my hp 255lph pump Quote Link to comment Share on other sites More sharing options...
80LS1T Posted October 2, 2006 Share Posted October 2, 2006 I would suggest 36lbs injectors also just because you dont want to have to upgrade again later if you want more power. The price difference wont be much either. I bought a set of slightly used 36lbs injectors off of Ebay for $200 and sold my stock injectors for like $75. You should be able to find a deal similar to that if you look for it. I think 30lbs will be enough for your goal but 36lbs would be better so you your duty cycles wont be so high.

nazar Posted October 2, 2006 Author Share Posted October 2, 2006 what do you guys think about my cam selection? Its on a 111lsa, 233/239 duration and .569/.577 lift with 1.6 rockers its based on one of the new xfi cams Quote Link to comment Share on other sites More sharing options...

Its on a 111lsa, 233/239 duration and .569/.577 lift with 1.6 rockers its based on one of the new xfi cams If your getting a custom grind, have you thought about going with a 4/7 swap. If I didn't get a deal on my heads/cam package I think I would have gone with one. Quote Link to comment Share on other sites More sharing options...
