    changing gear ratios

    If it's not possible could you make an allison stay together with a 3rd gear start, stock ratios, if you had the HP to do it? Stock third is 1.41. Maybe a high stall with a manual lock-up? When I used to pull often, 3rd and even 4th gear starts were very common, but in low transfer...

    changing gear ratios

    What would it take to change gear ratios in a 5 speed Allison? Make 3rd 1.81, 4th 1.20 and 5th .071 that way I could do a 3rd gear start and the allison would only need to shift two times. This would be for a drag truck.

    What system are you using to change the firing order? I did not see a parameter in EFI to change the firing order.

    LB7: LB7 alter fire cam injector wiring

    I have the wiring digram for the truck, looks like re-pinning the FICM would be the best route to go.

    LB7: LB7 alter fire cam injector wiring

    So I got my self an alter fire cam coming and was wondering how the injector harness is being modified, remember this is for a LB7. According to the new firing order 1-5-6-3-4-2-7-8 vs stock 1-2-7-8-4-5-6-3 it looks like I need to switch (2,5) (7,6) and (8,3), thanks.

    Bronze valve guides

    Well after more research, I see some use them and some don't. Are the bronze guides only for larger valves?

    Bronze valve guides

    Are bronze valve guides necessary and are there any cons to using bronze? I have set of bare stock LB7 heads I am getting ready for my build. I don't plan to port just new valves, retainers, keepers, guides, and better springs along with necessary machine work. This will be for a drag truck...
