FIRST OFF...

WELCOME!!!!!!

What headers are you using? I just posted a message in the Performance Section on Thorley Headers... I actually have set of headers laying around now... email me. I have p/s but am not sure what difference a fast ratio box means?

67 Camaro | 350 | 650 Speed Demon | Dual plane GMPP intake | MSD ignition | Secret Cam (I don't know what it IS!) | 2.02/1.60 Camel Humps ported | Thorley Tri-Y's | 8.5 10 bolt 3.73 | M22

The headers I had on the car are hookers which were made for camaro. the steering box is out of a 87 Z28 14.1 ratio. the frontend has all the g-machine goodies so it should handle well. the headers hit the #5 tube because this box is at least 1/4" wider to accomidate the larger gear. I read an article on the net "course correction" they built a 69 with the same box and mention hedman shortys. I would like to hear from someone first hand B4 I buy another set.

Some shorties fit fine but others exit right where the Z-bar goes so watch them too.

How far to the right do big-block motor mount brackets move the engine?

My BB Hedman 68190's fit fine on my now BB P/S, floor shift stick car.

It shocked me that the pass. side went in from the top.. And that the drivers side clear everything fine..

I do have NOS, BB frame and new poly mounts tho, which I figure help.. I got excited and peined the front tube on the pass. side to clear the rear upper A-arm shim bolt and A-arm flange when after I got them in, they probably should not have been touched..

I will say they are close to both floorboards tho..

Supprised me for good cheap headers!!

i only know about the small block stuff- if you have a big block, disregard this.


header fitment depends on what mounts the header prototype car had on it. a 302 and a 350 had mounts that put the engine in one spot- to the right and further back towards the firewall- where a 307 and 327 had the engine in another spot- forward and to the left.
if you have 327 mounts, and the header company used a 302 or 350 powered car to design the headers (which is very possible), then you might have clearance issues around the steering box if you have a 327 or 307 powered car. if they used a 327 car , the headers tend to be more universal.
my Nova is a factory 307 car, and still has the 307 mount setup. cheap dynomax headers clear everything great with no less than 1/4" of clearance at the tightest point at the stearing box. but the Hedmans i put on when the Dynomax headers got bent needed a 1/4" ding to clear.
so, in conclusion, either ding the header and live with it, or buy a set of shiny Jet Hot coated Dynomax headers from Jeg's for $220 or so- or uncoated for $115 or so.

you don't plan sincerity.
you have to make it up on the spot.

wanna hear about 20 years ago when i was too smart to know any better?

I purchased the BB Hedman 68196 ceramic coated units for my '67 RS 396 BB, but they don't fit worth a damn. They sit to low about 3 inches lower than the floor boards and about 3 inches above ground. They did clear the steering box by about .5 inches but hit the upper rear of the A frame on the passenger side and now I have a nice crease on that side.

Hi,

i have just pulled my engine out of a 69 rs/ss and figured this was a good as time as any to replace my steering box with a close ratio one. i did not know until reading this thread that you could use one out of an late model camaro. is there any fabrication or other things i should know. i have comp headers also.

Yes, you will need a new OR good P/S pitman arm b/c the manual box pitman arm won't fit the P/S box..

if you get a box out of a newer car, you will also need a certain rag joint- late 70's/early 80's truck, i think- and either get power steeering fluid lines made with the proper metric ends on the box side, or adapters to use your stock PS lines.

you don't plan sincerity.

What does OR stand for? This car already has power steering and a brand new pitman arm. Can I use that arm or do I need one specifically for that year? Where can I find the adapters?
By the way I got my new 383 today. My first transplant.

duh! (or) The upper case letters and 7 hours in a truck to pick up my engine hopefully buys me an excuse not to look completely foolish.

This is just one of the reasons I like the Doug Thorley 375Y headers. Had them on the old 350 motor and still using them on the 385 fastburn crate motor...with power steering, etc. Nothing hits or rubs and plenty of ground clearance.
