Hy guys,
So i plan to upgrade in future my stock 305 TBI .

-Edelbrock 68753 Headers
-Edelbrock exhaust
-Manifold Performer EGR (works with tbi i hope)

what u think about this combination, are this combionation realy adds arround 60hp?
im new so... never moddet an engnine ..

how many HP adds the manifold? heared about 17..

 

the better you can tune the computer, the more HP you will get from mods

 

my goal are add 60HP i dont want make some computer tuning so make upgrade to this mods no sense (under 50hp, for me) when u dont tune computer?

 

When I went from my stock headers to the edelbrock ones that I have now I saw a 22 HP increase. I don't think you can really get 60 hp more with a set of edelbrock headers?

 

ah ok im very pleased with 22 hp from the edelbrock headers.

i mean the edelbrock headers with an manifold, have to look wich, becaus i maybe want to install vortec heads, heared the GMPP are good? & edelbrock exhaust

but for the first stage of mod it, i just want headers, manifold, exhaust
..goal is 50-60hp ore more, of course

 

50-60 HP increase with TBI without computer tuning is a pipe dream.

As to the Vortec heads and intake manifold, look at the "Budget 350" sticky on the TBI forum. Even if you stay with 305, that's the info you need.
