dieing up hill?

ok i jus got my truck on the road i have a rebuild worked motor with a weber 38 outlaw with a carter fuel pump and a 8 gallon fuell cell .headers and some other odds nd end my truck run and drive fine on the road with no problem but when i got up long and steep hills it dies and i have to rev the shit out of it and slam it down to second gear does any one have any ideas
thanks derek

I'm not following you.. I think you will have to describe more about your engine and tuning...

Describe more of what you mean by dying... Other then that, I can only assume its because after gonig up the hill for so long you have too much load in too high of a gear and you need to downshift like normal...

ok here are the details its a 2.0 with weber38,portnpolished heads with match port intake nd header 3 inch exhaust irradium plugs bigger wires full rebuild and when i go up hils that are long it jus b ogges down and i have to down shif nd bring my revs way up and ill go to put it in 3rd nd it will jus die i have 15inch rims with low proz

...3 inch exhaust?! Whoa... I'm no expert, but I don't think its suppose to be that big!

Its obvious your losing power. How would you explain it dying? Die, as in you are in a gear, the rpms are low like 1k and it dies? Or is it at like 2-3K when it dies?

I'm thinking it may have something to do with your weber... Take it out on the highway and get into the rpm ranges above 3k and tell me what happens... If you suffer any power loss in that rpm range you need to tune your weber more...

Other then that, I think it could be your 3 inch exhaust or you just dunno how to shift! LOL!

I myself would'nt know what else there could be!

I don't think a weber 38 has any business being on a 2.0

It's mostlikely flooding out. You have to rev it so it'll burn the extra gas.

but remeber......

ok well i found out today that it is my sparkplugs there a fewmonths old but been threw hell and there iradium soo im gonna replace the plugs with some ngk plugs thanks for all the help

Hmm... see, I figure it was'nt something liek that. you said it was when flat... so ya...

I spent $10 a plug and got the Platinum FUSIONS! They are the hottest plugs you can get, and they are awesome!

my truck kept dying up hills and it was the fuel filter.
