bbc headers

[69trk]

I'm in need of some new headers and wondering which ones you guys are running on you're big block. I bought the tubular mounts with energy suspension polyurathane mounts and i think they were for small block. My headers were hitting the lower a-frame on one side and put a pretty good crease in them. So i'm replacing my mounts with solid ones that look to be about 1/2 to 1" longer which will help my new headers miss my a-frame. I'm not going to use the cheap hooker headers because one of the primary tubes hit my oil pan. I'm thinking about trying to find some with 2" primaries with a 3 1/2 collector. Do you guys think that these will be to big for my high reving 431 bb?

I don't know how well mine would fit a truck with the stock front end and mounts since I have mustang II and motor plates but I have hooker super comps from a malibu. I had a couple of the tubes slightly modified for extra clearance.


I wish you were closer I would let you try these

i have the cheap set of hookers and i just cut that tube that hit my oil pan and shortend it

[djracer]

I have never tried hedmans on a bb but they usually fit well.

I run 2" Hooker Super Comps with a Moroso kick out sump oilpan and have no issues with tubes touching.

i have hedmans and they do fit pretty good, but just wanting bigger primary tubes with larger collector and hedman doesn't make them to fit our trucks. I'm leaning on buying the hooker supercomps for a malibu like dj and regan are suggesting. Wish i could try your's dj. Anybody know how much shorter they are compared to the supercomps that are made for our trucks? I would like them to be up a little bit more, but if they are to much shorter then i would have to redo my exhaust. thanks for the help.

doug thorley tri-ys are good for SBC.... dont know about BBC

[smoknbarrels]

I have the "Tight Tubes" they are by headman I think and are a little expensive for the size of them I figure, but they fit awesome, with no clearance issues. and have heavy wall 2" primaries and a 3" collector. they are shorties, but I need them since I am bagged. but this way since I am running dual 3" exhaust i figure a 3" collector is fine.

and also since they are shorties, i can run my exhaust in the frame rails.

I have a set of Stans 2" try Y's for 73-87 BBC That fit perfect. I also used the 73' up motor mounts.

those stan headers look very nice, but where they merge into single pipes looks like they would be restrictive then they yet merge into a small collector. I guess they help with pulling exhaust out?

Called jet hot and they are having a 30% sale on their coated headers. Told me that they would be $545 and i wouldn't have to pay for shipping being that they have a facility here in oklahoma city. But as usual i'm a day late, they are sold out of the supercomps that fit our trucks and the chevelle headers. That would of been a savings over $200!!! dang it....

[69trk]

Just ordered my headers today. they are the supercomps for our trucks. i'll post pictures asap. i ordered them thru jet hot, couldn't get the 30% off though. after tax and everthing they were $840 ouch!!!! but tired of trying to find these damn things on sale. same price thru summit or jegs, but has better coatings.

[drag_72]

sorry to here the hair pulling news!!! man thats a pretty fast truck you got there... what kinda compression and stuff you runnin? is your truck lightend up any?

[69trk]

Just got off the phone with jet hot and they still haven't received my headers from hooker. They then said that they may not receive them until the 26th of may. So i called hooker myself and the lady that i talked to also said that they were still on back order. I ordered these damn things on the 14th of april. She also said that she will check with production and get back with me. So i thought that id go ahead and just cancel the hole thing so i called jet hot back. Then they told me that it would be 2weeks to get my money credited back to my account. So if i wait to get my money back that long i might get my headers by then... I'll never do business with these 2 companies again...

Im running the hooker super comp 2 tubes with 3 1/2 collectors coated headers on my 1972 blazer chassis and had to trim the hell out of booth frame rails on top. The plus side for me was I moved my engine back and down and with around 4 plus inches of drop and 26.5 tall tires I still have 10 inches to the ground from the collector. I have used chevelle headers in the past with some luck but after fitting these, im very happy. I will say putting a 598 talldeck with drag pan,bowtie prostock heads,tall valve covers and a victor intake into this stock front chassis was a little more than a 1 day job but the look is right on.My 4 inch cowl hood still gives me 2 plus inches over my air cleaner and my engine is 38 inches from pan to air cleaner lid.

Well i canceled my order with jet hot because of hooker not producing any headers. I received my money back and ordered a set through summit and received them today. This is what i should of done to begin with... Anyways, on the passengerside, one of the primary's hits my front crossmember. Should i grind the crossmember down or dimple the header? It doesn't need much at all. I already moved the motor back as far as i could without redrilling my motor mounts. I'll install the other side tomorrow. I tried to install it today, but ran out of patience. Looks like i'm going to have to remove the oil filter to allow me enough room to swing them in there. Once i have these things fitting, i'm going to take them to jet hot here in okc and have them coated. They said that they will give me a pretty good discount. Also, it looks like i'm going to have to replace my transmission crossmember with a tubular one.. Has anyone else had to do this? Also what one do you guys recommend?

[Outlaw72]

Hey man...sorry you had some bad luck here. Why are you needing to change your tranny mount?

If it were me....(and the OKC farmtruck did the same thing) I would just grind for clearance on the frame. That way you are not taking a hammer to your brand new headers. It's just me tho. Other people will do it their own way but dimpling the header I'm sure will be just fine also.

[69trk]

The supercomps don't hang as low as the hedmans that i had. Also, these headers are quite abit longer and come pretty close to the tranny crossmember. From the looks of it, i won't be able to run my exhaust below or above it because the exhaust tubing wont bend that short of an angle that quick..

[Outlaw72]

I hear ya.....wow.......I'm having the headache myself right now with brakes.....

[69trk]

Installed new supercomps yesterday. Had to buy a new transmission crossmember in order for exhaust with new cut outs to clear. Here's a few pictures....

Glad to see you finally got them in.

[69trk]

thanks drag truck, especially for your help on picking a crossmember.. I ended up finding one almost just like yours thru trans dapt. Summit racing has them.

You might consider reinforcing your crossmember.
