I am looking for maximum torque for my 305. I have been told that 1 5/8 primaries are the best to go with. Can anyone give me their own insight?

Thanx everyone,
Matt

 

yeah the smaller headers usually keep the torque strong and in the low range, so i have heard. alot of people are happy with hooker shorty headers.

 

I should probably go with mid-tubes for better power, shouldn't I?
Wold these be good mid-tubes? http://www.jegs.com/cgi-bin/ncommerc...17&prmenbr=361 I have heard they are great, but I am just looking for more opinions.

 

For anything less than a really wild 350, 1-5/8" headers are the way to go. You definitely don't need to go any bigger than that with a 305 until you're running a supercharger & good heads (and probably not even then!).

I've got a 350, went with 1-3/4" headers, & now wish that I'd stayed a bit smaller, at least until I bump the engine up to 383, maybe 396 cubes...

Good luck.

 

heddman headers are great for the money. it would be good to buy some high temp paint to cover them w/ before u put them on...the black paint will burn off the in the first few minutes of use,then look like ***.

 

Is it possible to go *smaller* than 1 5/8? For torque reasons? Should I sand the headers, then paint with hi-temp paint? Or just go over the factory black paint?

 

Just wanted to let you know that I have just installed the FlowTech headers on my car (shorty). The reason that I went with them is because they also had the "Y" pipe to go with it. I am pleased with them and am sure that you will also. They are also coated so I don't have to worry about the rust and turning colors.

 

How much did the headers cost, and from where? I am on a budget, so that is the biggest concern. I am thinking it will be cheaper and easier to just have an exhaust shop build me a y-pipe, so I am going to go that route.

 

You can go to flowtech.com and get all the info that you need. Plus I have a five year warranty with them. I priced the "Y" pipe to have it made and was a lot better off buying it.

 

Flowtech headers are cheap, it's about $180 for headers and y-pipe, but you get what you pay for. The headers are 1-1/2" primaries, not good for torque for a 305. I'd stick with some 1-5/8", like everyone else suggested.

 

Where did you get your 1 3/4 from?

 

I would recommend the Edelbrock TES headers....they aren't quite shorties, but aren't quite mid-length, and most are 1 5/8. They also come with a MUCH MUCH better than factory y-pipe.

How much do they TES's go for? And the y-pipe?

 

dont have to sand them,just scuff them up a little bit.

Sweet Jesus.. I am not paying $300 for a pair of headers, lol. The reason I am getting these http://www.jegs.com/cgi-bin/ncommerc...17&prmenbr=361 is because they are so darned cheap, and I have heard LOADS of good things about them. And nothing bad, for that matter.
