anyone out there running hooker super comp long tube headers with straight spark plugs? i am have a problem with the #7 plug. anyone have any answers or comments that will help?

 

What kind of heads are you running? If have a plug that they make a shorty for that should fix your problem. I believe that there was a guy i talked to that had the straight plug AFR's and he had to actually shorten his own spark plug. I believe his name is Phil87IROC on thirdgen.org if you want to do a search.

i am running the edelbrock performer heads.

 

just curious on how the fitment was on your car with those long tubes?
i have a 91 z28 with a blown 383 and these little custom shorties just won't cut it, i need a set of long tubes probably from hooker. what if any problems did you encounter?

 

I would like to know this as well, I am planning a 383 swap using the Hooker SC and a mufflex Y-pipe, any one using this combo?

 

installing the long tubes wasnt that bad. the only clearence problem you may have on the drivers side is a little corner on the control arm bracket. the passenger side is a little harder. the # 8 slip tube was hitting my control arm bracket, had to do some grinding there, then the #2 tube wouldnt clear the K-member. and the brake line may be a close fit to this tube also. i installed a mini-starter so that wasnt that bad at all.

 

Details about Hooker long tubes would be great for me too!

We just painted my '84 Navy Blue Metallic today.
I plan to do a Vortec head 383 this winter, I seem to have everything planned and figured out except the exhaust.

I really like the idea of a y-pipe and a single muffler in the back. I guess I just want something different.

 

I had no fit problems whatsoever with the longtubes. Well, I had to bend a brake line out of the way, but I dont really even see that as a problem. It seems that most people have the problems that flint502 had though. I have new rubber engine mounts, but dont think that that is the difference. I even ran the stock starter for a while. It was extreemly close, but worked. Now I have a LT1 starter which fits with pleny of room to spare. At worst you will have to do a little cutting/grinding. I ran duals so I really cant tell you as far as the y pipe though.

I saw this post and thought that I would chime in. I am running the hooker super comps. I think they are the 2210's. Anyway I had major problems with them. I have AFR 195 competition heads with straight plugs, BAD MOVE!!!! Hooker said that the super comps. clear all straight plug heads, DON'T LISTEN TO THEM!!! I went through three different sets of the same part number, they all fit different and worse each time. I tried the Accel shortie header plugs and they still hit on the electrode, still a good 1/4 inch from being seated to the head. Motor mounts don't make any difference on whether they will bolt up to the engine mechanically, if the motor is in the car though the motor mounts can make a differnce when it comes to frame clearance. I ended up cutting the number seven tube completely off and fabricating my own tube, the way it should have been done in the first place. I have seen some different types of angle plug heads have similar problems also, not quite hitting but close enough to fry the spark plug boot in a short order. I did have some clearance problems with the k-member very minimal but nothing that some massaging with the grinder and hammer wouldn't fix though. Best advice that I could give you is to do a lot of research on the heads that you plan on buying, talk to the manufacturer of the heads and the same goes with the manufacturer of the headers. The companies building the heads usually have a very good idea of whose headers will fit there heads, but your best bet is right here, talking to people who have used the various head and header combos out there and getting their feedback; no sales pitches just straight honest real world experience with the different products on the market today. Good luck and I hope that this info helps with your future build-ups. Happy 5.0 hunting!!!

 

Thanks for the info COOPS89IROC!! I was considering Super Comps but damn...not now. That does seem odd, because I have (or have helped) put Hooker headers on everything from a 65 Chevelle to a 292 6-cylinder truck and they all fit great.

I guess the exhaust really will be my worst headache on this otherwise straightforward project. My exhaust man can figure out something for pipes I'm sure.

 

Here is a link to a thread that should tell you anything you would ever want to know about these headers. http://www.thirdgen.org/techbb2/show...hreadid=148210 There is stuff on there from people with almost any type of head setup. I have ported LG4 heads on my motor right now and everything cleared fine. I have a set of sportsman II's that I am in the process of porting. They are angle plug and hopefully they fit as well as with my lg4 heads. From what I have read straight plug heads have the worst clearance issues. Here is a link that is on the page of Phil87Iroc's car. He has straght plug AFR's I believe. The link also has a pic of his home made shorty plug and socket.

95NateZ28, don't rule the hooker super comps. out completely. Don't get me wrong, I have used Hooker headers many times with great results, but this time I just had a heck of a time with the headers. The third gen doesn't make it very easy when it comes to using long-tubes, ground clearance and fit I think are the two biggest problems with long-tubes and our cars. You could order the same exact part number that I did and they will fit the first time or you could send them back three times like I did to end up fabricating them yourself anyway. I love the headers now that they are in the car, getting them in was a nightmare that I never would want to go through again. Good luck, header selecting is tedious to say the least with all of the different brands out there and EVERYBODY sells the BEST ONE for your car. Like I said do your research, which you have a good head start on and you will be pleased in the end.

 

thanks for all the replys on this subject. its great to get info from people that have gone threw this.

my 91 puts out over 700 hp with AFR 210cc race ready heads-angle plug, so finding long tube headers is pethetic compared to the new ls1 motors. 1 7/8 inch would be prime for this motor but good luck finding aftermarket headers this size for our cars.

i wonder if i can use hookers 1 7/8 inch long tube for the big block conversion and use some type of header flange adapter to fit it to my heads, just curious.

any opinions?

 

If you want larger than 1 3/4 hedman makes some. They are called hedman hustlers(I think that they may spell it a bit different). They come in 1 7/8 and 2" with 3.5" collectors I believe. I think that they are close to 600 bucks uncoated. They are expensive but do exist. If you are making that kind of power I would look into them.

I have Hooker LT's and AFR 195's with straight plugs. Hooker says that their headers fit most angle plug heads. They say there may be a problem with straight. I dimpled my number 7 primary a little bit and with a spark plug boot it will be fine. I had zero problems with any parts of the frame or control arms. But I do have new poly motor mounts. I think new motor mounts makes the difference.
