4.3L shorty style headers

[jimmydager]

Hey all,
I had a question for you reguarding headers. I have a 92 chevy silverado 4WD with a 4.3L v6 in it. I was looking to put on new headers and was wondering if they were worth all the hype. Do they really help out with horsepower and gas milage as much as they say they do? Has anyone installed these and how easy was it/ how much improvement did you see? WIll these just bolt up or will I need to do some adjustments to my exhause system? How easy are these to install for a handyman who is somewhat automotively inexperienced? WHat are the steps to installing these? will these even fit my engine? Here is a link to the ones that I am looking at. http://cgi.ebay.com/ebaymotors/ws/e...7968191666&rd=1
Thanks for all your help,

Ok... Well the headers you're looking at are for a V8. So, no they won't be an easy install.

I have a set of edlebrock direct fit shortys on my '94 5.7, and they were "easy" to install i guess, as long as you have a well equiped garage, with air tools. Your truck, being a 4.3 is pratically identical to a 5.7.

The important issue with "direct fit" headers is where your stock Y-pipe bolts up. My headers were almost identical to my manifolds, so no custom fit was needed.

On the one you posted (link didn't work for me, i cut and pasted the item #) http://cgi.ebay.com/ebaymotors/ws/eB...tem=7968191666 It has a weld on collector at the end.

Unless you're proficent with a welder, or plan on bringing it to a custom exhaust shop - not the way to go. Spend some time on www.edelbrock.com, research their header part numbers on google, and maybe you'll find it cheap. I bought mine at www.summitracing.com, along with a new y-pipe, to ensure a trouble free, rust free install. The performance is very noticable. Good Luck!
