I want to build a 750 horse LB7, that's streetable and reliable. Thoughts, comments and suggestions would be appreciated.
 
Put a cummins in it.LOL sorry drunk posting but more fuel, more air, and tunning will do it.

Built engine, built Trans, injectors, dual/modded cp3 and turbo(s). Lots of little details but that's the basic list if you want any kind of longevity out of it.
 
Extract massive amounts of money from your checkbook, continue this process until you exceed your budget. Then extract another 10K, after that keep telling yourself it was well worth it. Then sometime between your truck being in the shop and your tranny being rebuilt for the 5th time you decide maybe a 750hp dailydriver wasnt such a good idea, Happy hunting.

Well heres a question that could play a role in how long the truck lives. Does the op want a daily driver capable of 750hp, or do they want 750hp to drive daily.

Run some more conservative tuning on a daily basis, then run your hottest tune at the drags/pulls and truck will probably last alot longer than being run daily at 750hp. But as stated, 750hp is built motor and built tranny (with billet input and output) territory.

If you had a good no issues truck to start with and turned every last wrench yourself, ide like to believe it could be done for under $15k but thats a hip shot (Maybe a naive and conservative one) based on short block parts window shopping ive been doing for the last year and thinking about the money ive already spent on whats on my truck.
 
Thanks guys, but could you guys be more specific. Parts and places to get them or good places to start with etc. Thanks

Hahaha don't mind this guy his in depression over because he tried to LOL
 
just buy a complete engine from SoCal or Adrenaline Performance, gonna be in 20-50K range depending on how complete you want it

This is competitiondiesel.com, not builditforyou.com. If you can't do the legwork and search and learn what you need, I'd suggest paying a shop to build it for you.
 
Buying a complete engine from someone else that doesn't supply a warranty is like pissing in the wind! Sometimes your going to get wet! 750 Hp isn't hard to make when you do it right but to think it is going to be reliable at those power levels just isn't going to happen without a lot of involvement from you knowing what your doing. I can only recommend that you stop and learn before you jump in or you will end up like hundreds of others have. For a daily driver that's going to be used as a truck 450 RwHp is a very good stopping point for many reasons.
 
If you want 750 hp just throw a set of Carillo rods in the bottom end and have your stock pistons (if they look to be in good shape) delipped and coated (no real info on whether this helps or not but its cheap). you're already at about 3500 bucks. Headstuds are needed also. you can use the stock main bolts but main studs would be smart. some 60% over injectors and dual stock lbz pumps would be enough fuel. Throw a single s472 on top and that will be enough air. Assuming you do all the wrenching yourself, you're looking at about 10k depending on if you can find some deals on the dual fuelers and injectors.
 
520 HP DD= 6-7K over stock (trans lift pump EFI front end parts etc etc)
625/650 HP DD= 11K over stock (new turbo injectors FPR etc etc)
750 HP DD= 28K+ over stock (build the engine)
Just VERY rough numbers but you get the idea
there are a lot of build threads out there (esp on other websites) that take you through what other guys did

Good start, don't forget a trans about 4-5k. If your wanting to pull in a class and be somewhat competitive (depending on your area!) Your best bet would be a 2.6 charger and dial it back for the street. Or if you go with twins a set of tow twins would be fine. But if you do end up building the motor i'd put a set of 100% overs in there incase you bump up a charger size or twins etc. to make more power later on. I'd include more but you haven't given much info. on what your plans are with the truck...
 
If you do it in stages it wont be so hard to swallow. I did a little at a time and also bought used parts for half the price of new. As long as you can sit and wait on parts and take your time you can save a lot of money.
