I'm trying to determine if I even need the blower if I don't mini-tub and run big tires, otherwise it'll just be a tire eater. I've only had fast cars w/ all the modern TC to help put it down.

If I keep the LSA 1.9 blower (which is in my garage taunting me) I'm thinking again to save cash to go w/ the LS9 cam, as it will make more than I probably need. I want to do the engine build my self over the next few months and have Thomson tune it. Part of the fun for me is building it myself, well until I run into trouble. I have awesome luck... just spent 4 days doing ridetech front suspension and new brakes, was supposed to do rear suspension and brakes too. End result is front suspension sitting on tires (evidently the springs they sent are too soft) and no rear work done as I couldn't get c clips off axle due to sheared pinion pin retainer. 2 steps forward and 3 steps back.

Mine started off as frame off restoration in 2005 in a friends garage, but I am doing updates to it. Matt is just tweaking my original build, but it is looking great so far. The engine bay was my idea, but my car is long term build. I had to park it for years to generate more cash, but hopefully it will be finished soon. Mark Stielow builds a new one each time, but I do Mods to mine. This is my first car that I bought in 1983. Yes, mini-tubbed. No electronic traction control other than Detroit locker. If I had to do over, then I would have built an LS7 427 with LS9.

Originally it was supposed to be the Harrop TVS2300, but it is in the for sale section. You will want more power, so at the minimum it should be at LS418. I have same heads as Hellfire. Radiator was a custom built one, but I plan to have a spare built by C&R racing. Cooling has to be well planned, and you can't buy off the shelf unit.

I'm hoping to get this mostly done this summer and then enjoy it! I've managed that on a huge bike build (26 in front etc on a Street Glide) and haven't fiddled with my boat much, so once I get it good I can usually just enjoy my projects.

I went with a Griffin radiator with dual fans, seems to work well for most people. I'm not going to be able to go out and drive the wheels off on a track very often so my heating needs should be less. I agree after seeing the 7.0's w/ LS9 chargers at Sled Alley I was dreaming about one too haha.


I just bought the book "How to Build and Modify GM LS-Series Engines " to help with my build, anyone know of other good resources on putting this all together? I am trying to find an LSA specific assembly manual to get the torque, etc all right on the SC build, and figure out what else I need to buy to plumb it up.

I decided to give the BTR stage 3 a shot the same as you. What ecu are you going to run?

I'm figuring the GMPP LSA complete wiring kit, unless I can find a better looking aftermarket one that is just as complete for $1400ish, anyone have any ideas? Speartech is somehow $2600, even with injectors (which they don't identify) that's crazy.

Im running the holley HP EFI. The cable throttle body fits but I have not run the cable yet.
