: hooker super comp headers 1 3/4
sean jackson Jan 12th, 05, 12:04 PM :confused: hi I just order a new set of 1 3/4 super comp hooker headers and was told that my stock starter and milodon ( slight kickout ) and the flexplate may not work with these headers , does anybody have any input , 68 el camino with a 383 stroker , with a tci 400 . the milodon is a street strip oil pan and the tci flexplate is tci also
thunderstruck507 Jan 12th, 05, 12:08 PM why did you order them if it says they won't fit?
mfsr Jan 12th, 05, 2:21 PM That seems like an awefully large header unless it's a strip only car. I would have thought they would suggest a 1 5/8".

chevl71 Jan 12th, 05, 2:22 PM I have the Super Comps on my small block and a Summit side kickout oil pan. I had to clearance the one tube a little to fit the pan. I did have a stock starter but have replaced it with a mini.
bowtie455 Jan 12th, 05, 2:22 PM when i ordered my hooker 1 3/4's i got a mini-starter and a 350 non-external balanced flywheel.(fewer teeth).i bought a balance plate for the flywheel to work with the externally balanced crank on my 385 stroker.i too have a kick-out sump on my oil pan.i guess its all about clearance for those darn hooker headers.(gotta lov'em.) :D

In fact I'm getting ready to fire the 70 up, we finally got some sun graemlins/hurray.gif
Ditch that kickout if it's not too late!

70_FathomBlueMalibu Jan 12th, 05, 7:49 PM Is this for straight plug or angle plug heads?
I went thru this a bit when I put 1 3/4" Hooker SC's on my 355 with Canfield angle plug heads.
Hooker, Summit and Jeg's ALL told me that these headers would only work with a mini-starter and 153 tooth flywheel. Soooo, I went out and bought what they said I needed. When all was said and done, the new mini-starter and 153 tooth flywheel would NOT fit.
For the heck of it, I installed my stock starter and stock 168 tooth style flywheel and it all fit LIKE A GLOVE.
To this day I have no idea what Hooker, Summit and Jeg's were thinking.
BTW, I'm using a stock oil pan, so I can't help you out on that.
FYI, the Hooker instructions were correct in that I would have to sliiiightly tweak the column auto tranny linkage for clearance. I did so and had no problems (I've since gone to a B&M Pro Ratchet floor shifter). ALSO, the headers fit the car PERFECTLY and I DID NOT have to ding a single tube. The only other problem I had was that the ceramic coating sucked. It lasted about a year.
Anyway, kinda mixed reviews from me I guess, but I would definitely buy them again, only I would save myself some hassle about buying some of the things they recommended. Also, I would have bought them uncoated and sent them straight to Jet-Hot.
sean jackson Jan 13th, 05, 1:09 AM so far , so good, I pulled out the old mr.gasket 1 5/8 (which are for sale ) and after pulling down the starter and pulling the bolts on the engine mounts and removing the carb and hoisting the engine up , I was able to squeeze these pretty looking pipes into place , my man from arkansas , you were right on the money , I dont know what jegs or hooker or summit were talking about either , maybe its a money scam. anyhow I still havent set the engine back into the engine mounts but it looks like I'll have a 3/16 clearance between passenger pipe and the milodon pan . the only issue so far was that the heat shield from the starter was slightly touching the pipe , which can be beat into submission or notched back , I had heard all sorts of input for this year and was told everything from having to notch the crossmember , to buying a mini starter , to reducing the flywheel size , which is all stuff I just bought . the starter size though would be kinda cool , since the engine is a 12 to 1 compression and the stock starter does struggle a little smile.gif when firing up . when I get done this weekend I'll post the pics on my website , www.cardomain.com/ID/seanselky (http://www.cardomain.com/ID/seanselky) , thank you everyone for your help , I got way more responses from this forum than chevy talk!
red68chevL Jan 13th, 05, 2:33 AM Anybody that says they have to "clearance" or "ding" the header to get the starter to fit, should probably say "mash" or "flaten". I bought a set off of Ebay SBC Hooker Super comps, guy said he had to "clearance" the header for a drag car with a 168 tooth flywheel, when I got them the #8 pipe was mashed in half and the #2 pipe was oval as well. The amount of restriction he created by clearancing, might as well have been running manifolds.
I almost wonder if he was trying to fix the headers so he could put them in without lifting the motor.

Nice pix! After I saw your Milodon pan now I see why I needed to clearance for my Summit pan and you had room. My Super Comps needed a little submission at the pan because the Summit (and other brands) that form their kick-out with a small verticle rise at the bottom of the side angle whereas the Milodon slopes farther down and rolls under. The only other areas I had to clear were a few plugs since my heads are angle plugs.
How high are your collectors relative to your trans crossmember? Mine was a little too high and we had to make a tight bend to get under a smaller custom tubular crossmember.

If that's a picture of it at your website you could gain considerably more by maintaining the collector diameter at least to the crossover pipe. An x-pipe would be better than the long crossover tube.

sean jackson Jan 13th, 05, 2:15 PM well first i gotta start somewhere , I dont have money growing on trees and as for the size when your running a 12 to 1 compression wouldnt you want you engine to breathe better and yes i have looked into the x pipe and had asked a million question before I got them , but as the exhaust system sits now , of course i have to go to a 3" pipe , it still has 2 1/2 for the moment, and I epect to gain a little more performance and a better sounding engine , ... now for chevl 71 I didnt come close to hitting the crossmember I have 8 inches left before it comes close all that is hitting is the heat shield on the starter
68chevelle533 Jan 13th, 05, 7:35 PM I am running them in my 70. I have a stock starter and 168 tooth flywheel and it clears them both. The starter is very close to the header (maybe an 1/8" inch). I have a canton oil pan with no kickouts and the pass side has about an inch of clearance (driver side 3-4 inches). I did have a big issue with the crossmember clearance. I ended up taking a solid transmission mount and cutting and rewelding it to drop the rear of the transmission a full 1.5 inches. This helped, but I still had to cut the header collector and weld my 2.5 inch pipe at an angle to clear the trans crossmember.
sean jackson Jan 14th, 05, 2:33 PM what i was thinking of doing was to have a slight bow to the pipe and it should clear the crossmember with no problem , the car dosent sit that low , so I dont expect scrapin , not to mention I wont be going over speed bumps , but over all I'm pretty happy with how it all turned out !
sean jackson Apr 14th, 05, 11:35 AM they lied at jegs and summit , I had absolutely no problems with my 1 3/4 ceramic hooker super comp headers fitting my 383 stroker , the pan (milodon ) was close , but after wrapping it in heat wrap , it did the trick , I also wrapped the starter in a heat blanket, they were though a tight fit . after pulling the motor mount bolts and pushing the engine around with the help of a cherry picker I was able to squeeze em in ! www.cardomain.com/id/seanselky , good luck!
