zmanabba Posted May 16, 2011 Share Posted May 16, 2011 Who have you tried? I have an auto but I always look to see if 4 speed will also work in case I win the lottery. Seems to me Heddman works try part number 68196 to start. Summit or Jegs are both good suppliers. I use both. David Quote Link to comment Share on other sites More sharing options...
Dans '70 Z20 Posted May 16, 2011 Share Posted May 16, 2011 Not sure if you are looking for full length or 3/4 or block hugger. I believe Monteman71 used a set of Patriot 3/4 length headers on his 71-402 4spd. They fit great. Go to: www.monteman.com and look for tabs on bottom of homepage for 71-4spd project pics. Good pic of headers: http://www.monteman.com/New%20Project%2020037.html I believe "The Original" Dougs headers http://www.pertronix.com/prod/ex/dougs/default.aspx#PassengerCarHeaders and Sanderson (BB3 block hugger or C7 full length) may fit.....call 'em. http://www.sandersonheaders.com/Chevrolet-Chevelle/ ....or you could try Doug Thorley Headers: http://dougthorleyheaders.com/ A lot of people use Hooker headers with auto's but not sure of a stick shift. Hopefully others will chime in. Dan Quote Link to comment Share on other sites More sharing options...
7tonemonte Posted May 16, 2011 Share Posted May 16, 2011 RichG has a 454 4 speed,I know he had headers on it,not sure how much mods if any were needed, maybe he will see the thread and chime in on this Quote Link to comment Share on other sites More sharing options...

MCfan Posted May 16, 2011 Share Posted May 16, 2011 John, I'm planning to replace the long tube headers on my '70 402 4-speed soon. I can't identify the brand of the set that came with the car but they are circa 1974 and have been "relieved" in several areas. I've recently been advised by other club members that both Doug's and Hooker long-tube headers listed for a manual transmission will fit fine, but I don't yet have personal experience. Welcome to the club! Hope you will join up soon and share some photos of your '70 with us. Quote Link to comment Share on other sites More sharing options...
RichG Posted May 16, 2011 Share Posted May 16, 2011 I have BlackJack AK5000's on mine. Don't remember if BlackJack is a sub brand of one of the bigger guys or if it was it's own brand. I put them on in about 1983 or so. The AK is for Aluminum Kote. They fit perfectly. Don't interfere with clutch linkage or the brake valve on the frame.

Mikstudie Posted May 16, 2011 Share Posted May 16, 2011 I ran a set of Blackjacks for years,I slightly had to ping one tube on the drivers side to clear the clutch linkage Quote Link to comment Share on other sites More sharing options...
jml416 Posted May 17, 2011 Author Share Posted May 17, 2011 thanks for the help, i'll check into those Quote Link to comment Share on other sites More sharing options...
jml416 Posted May 22, 2011 Author Share Posted May 22, 2011 looks like the heddmen 68196 say will will fit a manual trans so i think i'll give them a try Quote Link to comment Share on other sites More sharing options...
Andreas Posted May 23, 2011 Share Posted May 23, 2011 Dynomax #86110 did the trick for my 5 speed. Needed to be dimpled to fit the control arm mounts, though... Quote Link to comment Share on other sites More sharing options...
James G. Posted June 3, 2011 Share Posted June 3, 2011 I have a Borg-Warner Super T-10 4-speed in my 1972 Monte Carlo with the original 454 in it. I am running Hooker Ceramic Coated Competition Headers in my car, 2" primary tube and 3.5" collector diameter. I am also running 3.5" exhaust all the way back, with the H pipe for tuning. It's a tight squeeze on the driver's side by the clutch linkage, but it does fit. The part number is 2455-1HKR and orderable right through Summit. Here is a link for you: http://www.summitracing.com/parts/HOK-2455-1HKR/ I hope this helps! -James Quote Link to comment Share on other sites More sharing options...
bigtankjones Posted June 6, 2011 Share Posted June 6, 2011 My Hooker headers,the same dia. as James but not coated, come really close to the break proportioning valve mounted on the frame. But it doesn't cause any break issues. Quote Link to comment Share on other sites More sharing options...
