well i just got done installing the holley pro-jection tbi intake, boy let me tell you i felt like mcguiver. all sorts of mods have to be made.So here we ge : the holley has bigger runners, 2" bores for upgrading tbi's(meybe the edlebro does too not sure right now)
, and better hood clearance.Now the deciding factor is ease of installation. the edlebrock from what i can tell is pretty close to a stock swap on a camaro, where as the holley looks easy but its not buy a long shot,you got to relocate the heater core line( not so bad), then the fun starts, the stock accel cable bracket is no good got to order seprate, you need a tbi spacer and you will still need to cut the fuel lines, you will also have to reroute some vacume lines too"brake booster and cruise diafram" is what i did.
you will also need a different egr to if you wantto use it loooks like an older style,BUT OTHER THAN THAT IT FITS. so what it comes to is how hard you want it to work and what you plan on doin whith your car. the holley is better to try and build something possibly powerful: or if you are just looking for somethig better than stock the edlebrock is the better choice.
i lost some of the off idle torq but gained some higher end hp so i am happy with it but am verry pissed at how hard it was

 

how was the midrange any change any other mods you have?

 

i got 65 lbs injectors and caprice cop chip..it seems a lot better

 

ahhhh TPI

 

????

 

No i only got a I.V. bag they call tbi trying to feed my 305. Some day i will do the tbi to tpi swap someday.

 

In my eyes it doesn't seem like a logical swap, money-wise, on an engine that is making any kind of decent power. TPI has some big restrictions as well as TBI.

 

i was gonna go for an aftermarket one since im planning on building up a 350 for it as soon as i get a few more miles from my tbi.

 

got to cutstom make cable brakets i cant find them anywhere

 

You might be able to find them on holley's or edelbrock's website.

 

holley doesnt sell them anymore, and lokar only sells new cables with brakets, and you really need the 2" bore tbi too its seems a little weah at the low end
