i was thinking of adding headers to my exhaust i already have flows with no cat and i want my car louder and faster and basically i just want my 305 faster and want to no the best horsepower gain for the buck. i would really like to now if headers is a good upgrade thanks.

 

hell yes! Back in the days of the 305, I installed a set of edelbrock TES headers and ypipe. I dropped a solid 2 tenths and sometimes three. I also noticed a massive increase in torque and could shift at a higher rpm. Don't go for the cheep stuff like flowtech, buy quality headers like SLP (probibly the best) or Edelbrock. It also made the car much louder and deeper.

If you are gonna go with headers then expect to pay some $$$ for a good setup. I just bought an SLP package brand new for about $500. My next move is to get them coated which will cost about another $150. You can probably get a better deal or find ways to save money, but after hearing the opinions of people on this board, the money I spent will be WELL worth it.

Man if my camaro were a rice-rocket all those mods would give me what...easily 50-60 hp!!!

 

I have a 91' RS that I put some summit headers on. (or, HAD them put on, rather) I noticed a DEcrease in torque, if anything. More noise from the engine area, too. If I had known then what I know now... I would have spent the "mod money" on something else.
I don't think headers are so effective on these (305 TBI)cars, like they are on other V8's. I would've spent the money on a gear or shift kit...
I'm not knocking headers.. I just didn't get any noticable power gains. Nothing I've done to this stupid car has increased power. Uh oh.. this is turning into a TBI post...hehee..

Everything I know I learned by messing it up at least once.

 

Don't buy Edlebrock headers, just look around this forum, many people have posted problems and weld restricions with them.

The best bang per beck headers have to be Headmen or Hooker headers. However from what I've been reading Headmens have some problems fiting T5 cars. Nothing bad about Hookers from what I hear.

 

i havent seen any posts slammin edelbrock headers, where can i find them? ive had mine for 3 months and have seen no problems with them.

Some 305s came with really sorry heads and wimpy cams. Such engines aren't worth the expense since the heads present the greatest restriction, not the exhaust manifolds. See what kind of cam is in your motor. The 305s with automatics often had lame cams in them.

There's no sense in making a lot of noise and not have the HP to back it up!

 

Zant69,jrr: i understand what you are saying, i installed hooker headers and cat-back now my car is **SLOWER** then before. now after i get a better engine it should be fine.

my car is running 17.7x in the 1/4'

ive had my Edlebrock TES headers for almost 2 years now and ive never had a problem with them. they sound and flow great.
