Headers
Im looking for headers for my 1985 chevy c10 lowered 5.5" in the front with a 1985 350 bored 40 over with 96-up stock vortec heads. I need a set of headers that will fit between the block and frame and also i can not have the header sit below the frame due to the truck being so low and also i have a cpp transmission crossmember i have installed and i wanna avoid hitting that so im going to have the exhaust go up and over that crossmember, could you give me some suggestions and part numbers to go with for my application? Pics too!!
Thanks!! |

Re: Headers
If I recall (SB) 350 most long tube header the driver side is lower( drop lower then other side).
Not sure 1990 up long tube header now days. But you may need to make your own to custom long tube header. Or use shorty headers. Or buy set headers you like, cut them change to your needs.

Re: Headers
Quote:
When I researched this last year, the only person I spoke with who knew about the port height relative to the bolt holes, as well as the spark plug position was Sanderson dealer Century Performance Center in Reno, NV. He gave me a couple P/Ns that would work, but I can't find my notes. Another note on port height relative to header bolt holes: Exhaust gasses are most active at the top of the port. Just like a car going around a turn, the gasses don't want to change direction when they hit the turn, so they are forced to the outside of the turn -- the top of the port. So, the last thing you want to do is cover up even a tiny part of the port with a head gasket or header flange. I ended up using 96-2000 cast iron manifolds, and even had to grind them open at the top around .100". But since I plan to add headers someday, please let me know if you find some that fit. I'm learning that Doug's makes a high quality product, so I would probably call them too. Here you can see that OEM style gaskets cover up the top of a Vortec port.  These are FelPro gaskets for a 96-up 5.7L engine, but I don't have the P/N.

Re: Headers
Just noticed my Vortec heads' port shape is different than yours, and the bolt holes are a little lower than yours relative to port height. Are yours 064 castings?

Re: Headers
OBX 92 Camaro long tube headers. They stay above the frame and clear everything in the engine bay.

Re: Headers
The long tubes are a d port, they're on my truck with dart heads.
Square port angle plug. Fit and clearance is great.

Re: Headers
So i found uncoated Clippsters for $200
http://www.summitracing.com/parts/pt...del/c10-pickup these might work but i would really like headers that exit level with the frame instead of at a downward angle. like longtubes that are 4 inches shorter to go above the crossmember http://www.jegs.com/i/Hedman/500/68460/10002/-1 these might be the ticket Last edited by TrailerTrash; 03-27-2016 at 11:18 AM. |
