Gen IV blocks can be wet or dry sleeved with good results, with dry sleeves being a tad more economical than the MID darton sleeves. The Darton dry sleeves are stronger than the factory LS7 sleeves which are prone to cracking if not careful. The MID sleeves are the strongest option for sleeved aluminum blocks. Talk to Steve at Race Engine Development for the best sleeve work. will that MID resleeved LS1 block be able to handle forced induction without failure or leaking coolant? thanks. |

Joseph you didnt answer my question? How much power in a small street cam? Friend of mine got the setup above WITH Stock Catback, stock Intake and stock TB the car drive really close to stock and pulls hard Made 560rwhp 505rwtq you can go with this setup with ported Intake and tb or the new FAST 102mm I;m sure 580rwhp shouldnt be a problem. |

btw, if i use a MID resleeved LS1 block will it be as strong as LS2/LS3/LS7 blocks? will that MID resleeved LS1 block be able to handle forced induction without failure or leaking coolant? thanks. |

Awesome power!!! What injectors are you using? What injector duty cycle did you see? |
Joseph, I was told once you port the stock throttlebody and intake the car is never the same. It causes surging and iratic idle. Is this true? |

i think it will be 4.185" bore X 4.125" stroke which will yield 454ci. Sorry, I had quoted the wrong thing earlier. This is what I meant to ask 4.250" stroke for:

i wish we could see a ported lsxr intake/tb combo on this |
so do you think strokin the ls7 to a 440 would help with drivablility issues with this cam? also, what results do you think you could see with the new fast combo and the 440 with this cam? on a side note, do you think you spray a 100 shot on top of this setup but with a 440? just getting some ideas... |
Aren't horse power and torque supposed to cross at 5252. If not then its not an accurate horsepower number. (Torque x Engine speed) / 5,252 = Horsepower |
