Performance Package
 

I am looking for some advice.

LT1 to LT4 perfermance package from edelbrock.

I know i could get it ported and polished for cheaper maybe.. But i am just really wondering about what type of performance gain I could expect from this package.

maybe 30hp

30 is probably a little undershot, but i do believe what he meant is you would be blowing your money.

if you're just looking for a little more fun, i'd look into lloyd elliott's LE1 package. www.elliottsportworks.com

Edelbrock is overpriced for what you get. The LT1-LT4 conversion is overpriced for what you get. That's 2x overpriced for what you get ;)

Alright, so the math may not work out exactly like that, but you get my point. Check out the LE packages as Wham suggested, you'll get a lot more bang for your buck that way. Other places to check out include Advanced Inductions and Dragon Race Engineering.
