i was thinking of doing the conversion and was just wondering what kind of power does that make?

 

Do a search. This has been beaten to death hundreds of times.

Or, the quick answer.

LT4 conversion + supporting modifications = 340-360whp, mid-low 12s.
AI or LE heads/cam package + supporting modifications = 400+whp, deep 12s, high 11s.

 

ok sorry i should looked it up but thanks for the info

 

Not enough to justify the cost.

RamAir95TA nailed it on the head.

 

yea dont ask that question on here LOL you will hear nothing but bad things

 

ok so the lt4 isnt what its cracked up to be well least for the money. and another quick question were do you go to buy this le kit or look at them?

 

haha the LT4 conversion is a joke Dont waste your money put it into a better
setup

ok so the car would have to be retuned for the added air right?

 

Yes a tune is necessary for the car to run/perform right.

 

yes it will need a full hands on tune! A mail order tune is good enough to get ya to the tuner, but thats it.

 

If your going all out with GM parts, the LT4 does have more potential, with that said 99% of people will never use LT1 stuff to its full potential either. So its not really worth it to go LT4 for most.

 

ok so with the le1 kit from elliot sport works with the best emissions friendly cam what would be nessary for it to run to its full potienshal like stall converter and rear gears and well like said befor a tune. but would a diffrent intake be a must and could it be ran with out a tune for a little. or would i need at least a programer

 

Send your computer out for a mailorder tune and then when you get the money have it dyno tuned locally. I would sent it to PCMforless, Bryan specializes in LT1's and has done many many LE setups so the mailorder will be pretty damn on. I ran his mailorder tune in my car for over a year until I had it tuned with zero negative effects, the a/f was dead on. I recently had him dyno tune the car and he was able to make the car drive a little nicer and picked up some good hp and tq throughout by changing the timing.

 

ok what other supporting mods would have to be done like injectors fuel pumps ect?

 

-SVO 30# Injectors would be sufficient. I'm using them with a more aggressive package than what your looking at and they aren't near maxing out yet.
-Racetronix 255 Fuel Pump Kit
-Intake Manifold Ported by Lloyd Elliot
-52MM or 58MM Throttle Body
-Rockers, Pushrods, Gaskets, Timing Chain etc.

 

ok sounds alittle expensive so i dought i get that done till im out of high school but im deffently interested in making that setup

 

it ends up over 3k easy
