Clifford Exhaust Mani Install

[Mthumphrey]

I bought a Clifford exhaust manifold (http://www.cliffordperformance.net/M...gory_Code=C250 ) for my 66 C10 (250 i6). Will it install correctly with my original intake? Or do I need to wait until I get a new intake?

Thanks guys!

You will need an aftermarket intake to run the headers.

You can use the stock intake manifold if you can find a way to water heat it...I believe Langdons Stovebolt.com makes a water heating plate for the 1 barrel intake manifold..if not..its for the offenhouser. What are you doing to the engine? Are you doing head work? And thing to the bottom end? I can give you a ton of info if I know what you want...the type of carb you use is fairly critical pending on what you do. Pm me or let me know.

Was hoping you'd chime in TJ. I know that there are mods required to use the stock manifolds, but wasn't 100% what all was involved.

Thanks guys! I am looking to upgrade the intake and exhaust manifold to get full dual exhaust. Looking to upgrade the horse a little bit, but I want it to sound good. I have the manifold and was hoping that I could install it now instead of waiting until I determine the exact set-up I want on the intake and carb.

These are pictures of the engine at the moment...

the only thing you will have to do is grind the little acorn fasteners that hold the intake and exhaust together. this is because the thickness of intake and exhaust are different thicknes or you can grind the manifold or exhaust down to match. i never had manifold heat on my 250 and it ran fine. edelbrock manifold and 390 holley carb. but i live in cali.

Ok...So...If you purchase a Clifford Intake as well...and install a 390 holley or jet down a 500 edelbrock and hei it'll perform a little better. Flowmaster 40 series mufflers sound great. Nice deep tone at idle..and loud angry tone at rpm. Here's a vid of mine, Its an ol worn out 292 with a 600 Edelbrock, CLifford intake and headers and flowmaster exhaust. Its internally stock. https://www.youtube.com/watch?v=YoiM0nIA_7c A good HEI would be a Pertronix Ignitor II or an original GM Hei which is available from Landon's Stovebolt.com. The 250 has many options for power...I'd do a little head work to...Bigger intake valves and lump port the head...you feel a good increase there.
