502 in my 63 frame.. what kind of headers!?

[1942]

Hei, can someone give me a link to a set off headers that will fit in my 63 frame? dosent matter if the motor mounts has to be modified/changed....

I have tried 2 different headers now ( both 2" primary ) and both of the are to wide on the top of the frame...

I guees i i can use 67-72 or 73-87 BBC headers but i cant find any headers with ca 2 or 2-1/16" primary tube diameter and 3.5 Collector..


hers a picture!

Look like they will fit, but not on the other side.....

After the picture was taken i`ve also cutted and modify the firewall a little bit for better claerence...



Best regards from norway !

Why not just trim the top of the frame in 1/2" to allow clearance?

I used Headmen They fit realy well. Take a look at my build (farmers big block)
If you need it I can dig up the part number.

Hei Ståle

You will have to trim a little from the top flange of the frame, aproximately 3/4" to 1" (20-25mm) I typically use a '73-'87 frame as a reference for the frame trimming. I have also used the '73-'87 headers from Hedman, #69110. Although those have 1-3/4" primaries. In my opinion, those should flow well enough for a 502 unless it is quite radical.

I have heard that big block Chevelle headers will fit, but I don't know what modifications are necessary. Those will not work if you still have the bellhousing crossmember in place. The Chevelle headers are available in 2"+ primaries.

Okey, thanks for helping! i will order new headers sonn.

I have cutted a little bit in the frame...But in norway its il leagel to cutt in the frame. and if they know about some thing who is not leagel, they will take the licens plates ( ! ) if you will change somthing on the car you have to apply to the authorities

To my knowledge, there are not any big block headers that will fit without trimming the frame. If you make nice smooth flowing cuts and sand them nicely and paint, do you think they will know? Is it much trouble to apply to the authorities? Would it be helpful if I sent you some pictures?

I used A set of hooker headers for a 71 chevelle big block,Then do not hang way down like most truck headers ,but you will have to use a tubular drop cross member for the transmission or the collectors will be to close to the stock trans, cross member. All I had to do was lightly grind the frame around the #3 and cylinder area ,maybe a 1/8". They are long tube headers also. Fit very nice.!!!! Look at page four of my build link at the bottom of the post and you can see how they fit my stock 66 frame .

The Hooker 2455's are known to fit C10's

I used Sanderson C6 headers on my 454
