And more, just keep in mind also that the ports are raised by 1/2" on these heads.
I've had 2 sets of 6901's, The ports are all square......... well, kind of...........
ouch!.. this is going to be some tight quarters. Almost reminds me of my big-block Torino with 2 1/8" super comp headers. I made special tools just for changing plugs on that car.
Thanks you very much for your time to post pic's here. It is much appreciated. I will be gone on our trip for the next week.. but I'll surely be thinking of ways to skin this kitty when we get back.
I will say this on a more positive note though. Those tubes do actually come off the flange quite a ways before they turn down.. so maybe I can go up towards the valve covers and then head back for the collector turn-down from there?
I also noticed that my headers have not one little ding in them anywhere, so maybe this won't be as bad as I'm expecting it to be. Dunno.. guessin' I'm just gonna have to mock it all up with my bare block and heads to see what's possible.
Thanks again for the time and good luck on the topend. Fingers crossed that it's just another gasket replacement.
be out of town for a bit.. but I will take pictures to try and figure out what the heck I even have here. Might be an off-shoot type brand too.. but at least they were not damaged or clearanced so they must have fit decent enough.
later guys.. thanks again for the input and help
Big Block Torino ? Try a 67 BB Stang !! That's the reason I cut these towers back first off when I bought the car and pulled the motor. I had Hookers in that Stang...............never again !! When I sold it, I had cut the Hookers off and installed a set of 428CJ manifolds. They didn't flow nearly what the Hookers did, but I ended the 6 hour ordeal of bolting/unbolting the headers. (and the leaks)
Been there, 69 Mach 1 428CJ. My first headers were a set of "JR's" that were total trash. They hit everything. One of the collectors was welded on cockeyed and pointed up to the floor board.
The second set were Hedmans that fit much better, but required the use of very shallow header bolts so as not to hit the towers. You had to lift the engine off of the mounts to remove the bolts.
sorry for the extremely late reply lol. started my 4th year electrical...bit overloaded at the moment..heres some pics though, i built #5 and # 6 tubes for the hedmans to clear, pics aint the best though..hope they help if not i can try and get better ones.
thanks so much for the pic's you guys have posted for me. very easy to see why shorty's are so popular in these cars.
A bit off-topic.. how long did it take you guys to notch your towers?
With work starting back up soon.. a bit worried if I can accomplish it over a single weekend.
Dunno why anyone would chose shortys in these cars. The install is a piece of cake, the right side falls out by itself when you unbolt it. The left only needs the motor lifted to get it in place. Notching is easy, doesn't take long with the engine out. Just cut the portion out, cut steel to fit in it's place and weld it. You will definitely thank yourself afterwards when bolting the headers in or dealing with plug changes.
Long tubes only for me and mine. I'll make them work.. or I'll just make them, period. Good to hear about the towers finishing time. Thanks for the heads up.
shock tower was an easy job...won't take you too long at all. only issue with mine was i ran out of gas and used flux core lol. hate that stuff.
Shock tower mod's. Really didn't want to stray too far off topic.. or for too long.. but this is my conundrum here.
For the long term project, I don't want to "notch" my towers in the traditional sense. I want to move them outwards and reduce the width and diameter as they wrap around the topside of the spring. Look at the old pro-stock stuff that had Boss 9's and cammer's stuffed in there. Basically just a mini version of the original tower as it gets shrunk, pushed out(springs end up more vertical), and shortened up a tad. This will allow my planned coil-over package to fit nice and tight within the new tower and maximize space around it for better custom headers down the road when I swap over to a more serious set of heads and engine combo. Plus, at that juncture my engine setback will gain me more tower clearance as well.
Unfortunately, nothing is really planned out, coil overs will set me back another full $G$ and the budget just won't be there yet as I try to toss it all together in such quick fashion. This week will be busy and I'm planning on mocking my block and heads into the empty bay to see what I've got to work with here. Rather chop these headers all to hell and throw them away.. than cut my towers in a manor that will require twice as much work to get them back towards the direction I wanted to go in the first place. I wonder how SPark is doing on his "pro-stock" Mav project. That's similar to what mine will be from a tower mod standpoint.
Thanks much for the input here guys.
What they did in the old days to those cars was adapt different towers out of another application into the car they were working on. If you need a set of headers to experiment with I'll sell you my old ones cheap ($25 + the ride ?)
hmmm.. I did not know that. I thought they simply used the same tower after they lopped off the fatter section width and melted it all back together.
And thanks much for the offer. Mine are here and not anything I'd worry about practicing on anyways. Once I get the stubbed flanges made for the new port design.. I'm about 40% of the way there anyways. lol
Hoping to move some things around the garage today so I can mock my stuff up and get some hard measurements to work with here.
Thanks again guys.
Seems like I read somewhere they used the old T-bird towers in those cars. I'm assuming those from the 64-66 ?
