I'd leave it an LB7. To me, 3.8 and 4.1 aren't that bad. I was thinking like 7 was bad?? Also, why are you talking about pulling the heads? You can do injectors on an LB7 in a day.;)

You could pull all the injectors and have them sent out and tested while you have the tips extrude honed.

3.8 and 4.1 are enough to make it smoke white at Idle, and I dont like driving it around looking like a P.O.S. ;) I just figured If I was going to pull it apart I might aswell do Studs and get the heads checked out since it has 200k on it. Other then the white smoke it runs and drives good.

I was just saying doing injectors and pulling the heads and doing studs are two totally different jobs. Just do the injectors and pull the heads when the truck says its time.:D

Yeah,, maybe :D I have had about 50 different plans already in the last 3 days, I guess I will decide when I start stripping it down. Currently My 05 is not finished, my Built motor is not finished, My Super Duty is Broke :eek: And my Reg Cab needs Injectors :banghead:

Nice looking truck!!!:thumb:

If you plan on building it for a specific class like Jerry said say SS in NHRDA then you can't have a 4 link or back halfed truck, you must have the battery(s) forward of the firewall and the fuel tank in the stock position. If you back half and 4 link it then you are into Prostreet and the price of racing goes up in a hurry if you want to be competitive. Plus the engine is on the ragged edge and get expensive in a hurry. We scattered two motors, three big turbos, three trannies and 3 tc's last year and that gets expensive in a hurry.

I'd keep it in the Superstreet class and until you get it built, try the 11.90 index class, that will be a fun class and lots of trucks to race. That's another problem with Prostreet, usually not many of them at a race and lots of waiting around and no one to race half the time.

I'm racing my truck both in SS and the 11.90 class this year. Looking forward to it and looking forward to watching the progress of your truck. Good Luck.:thumb:

I don't think SS is any cheaper to build a truck to run in than Prostreet. This is just considering to win SS you need to be able to run low 10's and hold together to be competitive in my area. Hell there were trucks running 9's in SS at the last event in Div 6 snd not one Pro street ran a 9!! Maybe other divisions aren't quite as fast though.

11.90 sounds like the best bet and the most fun IMO. Unless you got lots of money to burn!!

personally i would change it to a lly. having two trucks with the same engine would make it really easy to swap parts between the two if needed.

The key here is hold together, lots of races are won by much slower trucks because they hold together. I agree however that you need a 10 sec truck to have a realistic chance in SS. There is not many 9 sec trucks in SS. Maybe 3 or 4 in the whole of North America last year, who knows this year.:thumb:

Jason leave it LB7 . we all know the LB7's are the fastest out there :stirthepot2: lmao

About the only thing left that you can call an LB7 on those trucks is the crank and the block. And the reason they are the quickest is they were the cheapest to build at the time due to their higher availability and cheaper price and that's it. The injector hold downs suck, as does changing injectors. If you can build anyone of them build an LBZ, can get more RPM out if them, but as stated if you already have an LLY use one of those.:thumb:

Probably going to leave it a LB7 for simplicity reasons (AKA I hate wiring) ;) On a positive not the LLY left the Garage today under it's own power :woott: Super Duty is next then the LB7 will go under the knife ;)
