    US7, that's got to be some kind of record! My last post on this thread was 10 months ago!!!

    The S-10 sounds like a great project. I had an '85 that I bought new. My Ex-woman blew it up...ran it without oil or water or maybe without either.

    Well, I have come a long way since this post. I have been reading LS1Tech every day and have picked up maybe 10 books on the subject...engine building and blueprinting. I feel very comfortable with the options I have choosen. Option A is basically right out of the box. Options B and C are naturally apsirated, forged, solid-roller, dry-sump configurations:

    A) LS7 crate with a better cam and Tech3 EFI. (big bucks)
    B) LS2 402 with GM-PCM and EFILive. (less bucks)
    C) SBC 377(+) with MassFlo EFI. (least bucks)

    Option B is looking really good. If I want the displacement, I can opt for the new dry-sleeve LS2, which easily makes a 427ci engine. No worries about reliability because I won't be spraying, using a turbo or blower...I don't think!

    I see you are running a higher compression ratio than what I usually see for pump gas (we only have 91 out here). Are you planning on using race gas? Or, perhaps you have built in other knock mitigating features?

    Is the block you are using an original 400, or after-market? It's been a long time since I have looked at the specs, but I though the 350 journals were the smaller (more desireable) ones.

    My chassis will be here in about 3-4 weeks. I can hardly wait!!! Good luck with your build and please keep me posted. Don't wait 10 months to make another post! I hope my car will be on the road by then! I chose red. Attached is a nice photo of what my car will look like.

    I feel more like I do now than I did when I got here.

    I always run 110 Turbo Blue Race Fuel.
    That's a cool car in the picture, hopefully yours will turn out as Cool. The block is an original 400 out of a 4wd truck,
    and the crankshaft is a Scat it has 400 Main journals and a 3.5" stroke, which is .020 more than a stock 350's stroke.
    So it turns out to be 379 c.i.
    The new LS7 small block in the new vette is awsome titanium rods
    and I think 500 horsepower off the showroom floor.
    Lots of cash though, I can't do that, plus I feel alot better when
    I run down the track or start it up and I built it, top to bottom.
    That's what I really like.
    So what is the fastest you have been?
    or how much power have you ever experienced?
    Thanks...

    Okay, the higher octane makes sense. Luckily, the body of the car is complete from the factory. So it should come out looking identical to the photo. How well it runs will be up to the builder...me! I will use nothing but top-quality parts. I think it will be great when completed. There will be an on-line build journal when I get started...

    Good find. I hear those original 400 blocks are getting harder to get. You are doing the engine assy yourself? That's something I would really like to do. I can't make the time to learn that right now. The LS7 is more of a last resort. It would be nice, but expensive, and and there are lots of things to sort out if I go that route. The LS2 or SBC with EFI are both preferred.

    Fastest I have been? In a car...an Ultima to about 150. On a road course...about 110. I had the dubious pleasure of going to the US-GP this year. The cool part was that a friend of mine picked me up at Indy air port in his recently completed GTR! After checking into the hotel, he threw me the keys and I drove over to the Speedway. On a bike...about 170. I have had lots of bikes. What about you?

    I have only been to about 140 in a car never really rode any bikes, mainly because I love going fast and I'd probably get hurt or worse because some car pulls out in front of me at 150+,
    So I have always stayed away from them. About the engine build
    I do my own engines, only learning from my uncle for the past 10 years or so, I'm only 25.
    The 400 Block I got ahold of costed me $300, propably could of found one cheaper but My friend found it in Anderson, IN
    And we took his truck up there to pick it up. I live in Tell City, IN.
    Can't wait to see the start of your build, Thanks
