Engine build help
Hey everyone a while back I ended up spinning a lifter in my stock ls3. So I’ve been researching and putting together a plan to build the next motor for the car. Below is what I have come up with and would like any and all input on this. Thanks in advance.
Thompson Motorsport outlaw 427 dart shplsnext short block Diamond pistons Dart center 8 counter weight crank Manley pro I beam rods 4.125 bore 4.0 stroke Dart windage tray stud kit ARP mains and head bolts Thompson Motorsport stage 3 turbo cam 240/246 .630/.630@.050 116.5+6 Frankenstein M311 heads with inconel exhaust valves AGP twins 62/62 ball bearing .82 AR Fuel is agp triple pumps 1600cc injector running on E85 This is a street car that may see the track from time to time so was thinking so the car isn’t lazy to have my static compression ratio about 10.2-1 thoughts? |

With E85, on't be afraid to bump it up to 10.5:1. That is what I had with my LSX427 and AGP 65/65s. It wasn't lazy.
