barefoot bob Posted August 14, 2007 Share Posted August 14, 2007 I think i found my next motor ls1 steel block forged crank titanium rods 9:1 pistons 409 cubic inches small blower delphi electronics intercooler all accesories larg intake, aluminum heads 630 hp 650 ft pnds tourqe free dyno after install they tell me the steel block will be stronger for dependability and he saise it will be a very dependable motor Quote Link to comment Share on other sites More sharing options...
dunefreak Posted August 14, 2007 Share Posted August 14, 2007 I doubt the steel block makes much of a difference for reliability, but otherwise it sounds good Bob. Are you getting a decent deal on it? Quote Link to comment Share on other sites More sharing options...
sanddunesaddict Posted August 14, 2007 Share Posted August 14, 2007 Actually a iron block will be more reliable and make more horsepower but at much higher numbers than stated. At a certain point you get cylinder wall deflection and causes the rings not to fully seal. I have heard of it at real high horsepower levels in small and big blocks. Thats why back in the day they used to fill the blocks with cement for top fuel before they had Billet blocks Quote Link to comment Share on other sites More sharing options...

barefoot bob Posted August 14, 2007 Author Share Posted August 14, 2007 (edited) im getting an excellent deal customer built the motor and couldnt pay for it. higher nickle content in steel slows cylinder wall deflection earlier 60s motors didnt always have a high nickle content so big boost gains saused heavy cyl deflection quicker the power gains in this motor dont match the power of my blown 383 but it does slightly exceed the hp gains of my old 454 small block 600 hp 575 tourqe which was almost a perfect balance for the cars weight , gearing, and tires so matching it down to those spects should make it quite enjoyable. where my 383 with the big blower is completly over powering the car plus the over heating and no reliability why is it steel i dont know i like aluminum but my springs are rated for a heavier iron motor 100 pounds approx. overall i am being told repeatedly that the ls1 is more dependable than the small block by lots of people and there are several customers that are runing small blower ls1s season after season with no trouble. im hoping for that concept i need dependability my car works flawlessly other than the motor woes so i threw this question out there to see if there is any negative feedback about ls1s vs small blocks or anything i should ask or look for before i purchase. everything ive seen and heard tells me ls1 is dependable and the hp range seems good to me.b and see if anybody has anything to say about the steel ls1 to the aluminum ls1 supposedly this motor is not a stroker , he says aluminum the max is 402 ci steel 409 ci any rebuttle ?? EDIT: correction the motor has a 4" stroke crank its basicly an ls1 turned into a small bore 427 but he says its as far as you can go on that block. 409 cubes Edited August 14, 2007 by barefoot bob Quote Link to comment Share on other sites More sharing options...
Dusty Rhodes Posted August 14, 2007 Share Posted August 14, 2007 I am a dumb a$$ so don't be too harsh, but doesn't iron block mean heavier engine, needing more HP to compensate for the extra weight, meaning it negates the horse power gain?

trqjnky Posted August 14, 2007 Share Posted August 14, 2007 yea, those motors are great. only problem with them is you can only go to about 1100 hp with em while boosting. anything over that and you lift the heads. or you can have a few more head studs machined in, which no one has tried yet. here is a video of a turbo kit my friend builds that is a bolt on to those motors...Its installed on a guys truck that i used to run around with back in the midwest. its all stock block with valve springs, injectors, and a tune. Oh yea, its a daily driven truck that has been taken out and drivin in the snow.... perfectly driveable on the street... see bob, you ont have to lose your hp. this is a much more reliable way to make it....

Thats what Ill be using thats what i ended up buying the 415 inch escalade block its aluminum alrigfht the motor is awsom. the escalade block also also is .2 liters bigger than the ls6 in stock form runs cool in the heat the 610 hp version has less tourqe ask them about the middle package you get more tourqe thats the version i bought :mc_smiley: 600 hp 575 trq Edited October 1, 2007 by barefoot bob Quote Link to comment Share on other sites More sharing options...
