jumping a tooth for timing

[randyswelding]

i got the front cover off workin on the pump the 2 bolts on the motors side of the ksb came loose on me and lost the oring so i just got that fixed and now time for reassembly,would it be worth wild to jump a tooth in timing with the 6x16s im runnin, i need power at both low and higher rpms and which way do i rotate it clockwise i thought but i dont remember,thanks guys

as far as I know jumping a tooth is only for guys that are after max power. On a daily driven truck, especially one that gets worked I wouldn't jump a tooth, but that's just me.

if you jump a tooth you can retard the pump below stock mark and get close to your current timing for work then adavnce the pump past the stock mark and have lots of advance for fun. your pump should be to the head now so a tooth jumped and retarded should put you close to the same.

what way counter clockwise or clock wise thats what i need to know asap! or my dad will be askin me why are ya doin that and then i tell him i nneeed more power to try and get 400+hp goal with this motor

[dpuckett]

For 400hp, I'd leave it on the tooth it is.

Yeah I say for a 12k pound truck, leave it alone.

Pump shaft should be at 12 o'clock to keep the key from falling.

Ya I figured that out after I got the gear where it needed to be!man did that suck!!but I got it and it'll be done today after work finally,I figured I'd try a tooth and stock mark on the cover since the other motor will be ready to go in late august:) thanks guys for the info

Ok I like the tooth jump a lot more usable power and less smoke down low until 2k then all hell breaks loose,I kicked the rear around the front of the truck I did a donut with tryin and I wiegh in at 12k that's awsone

That's sweet right there, where's the video??

[randyswelding]

Sorry no video I lost #1s hole I'm gettin oil out of the manifold and already changed guide seals to see if thatd help and it didn't oooppsy now got to save for the other motor but the power was awsome though just on a 400k miles didn't help

I think the problem is your weight. If you hot rod a truck that is heavy as hell its gonna bust. Lots of timming and heavy engine load is not real cool. I have blown a few gassers due to lots O timing and hauling heavy.

[dpuckett]

I told you to leave it be......

There is a running take-out for sale in the classifieds for $750- Chicago area. 300K, but this time you have a better idea of what to do and not to do.

Well I got a motor in the machine shop for the truck that's why I wasn't too worried bout playin and I did it,so weight and timing is bad so I think a set of 435s and 1/8 bump on the stock tooth on the pump I should be good for hopefully 400hp that's what I'm wantin.I did learn my lesson with havin 6x16 sticks and havin a hole in the cooler boot and still hittin the dyno so there is a chance that I washed a cylinder
