250 inline 6.. headers, cam, intake, 4 brl?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Jbesotes · 02-26-2010, 02:23 AM

I have a stock 250 in my c-10 short bed chevy.
I have headers and a four barrel intake from clifford racing.
I am looking into getting a 264 Hydro Clifford Cam (comes with lifters, pushrods, springs and retanor clips), as well as needing to get a Webber 38 Carbuerator to go allong with the package.

I am looking to gain a little power but still keep a nice ride to where i dont have to work on the motor every weekend. I want to be able to start it up and drive it without having all of the problems that I am having with my single barrel carbuerator that is on the stock intake right now.

If anyone has any sugestions I am all ears.

Also If you know of any other companies other than clifford racing 6=8, where 6 cylinder parts can be purchased?

Thank You

That will be a nice setup and will work well for you. For a little cheaper carb, an Edelbrock 500cfm would work very well right out of the box. Also, the Offy intake might work a bit better over the Clifford.

www.stoveboltengineco.com is run by Tom Langdon and is a great company for 6 cyl parts. There's also a supplier in AZ, but he mostly deals with the earlier gen 6 cyl's.

Have some head work done. Bigger valves and mill the head.

Before doing any mods I would first do a compression check and make sure the engine is worthy of the upgrades.Like low'n slow said the heads need help on these 6 cyl.They flow like molasses.
I would suggest the first upgrade be an HEI.By far one of the best mods to do to any truck of this era.

I'll second this one for sure. Totally acts like a different setup completely to me... I'm not into setting the gap/dwell at prescribed intervals (and I'm not exactly good at it to begin with) - it's one of those things that if you just dont have the time/good know how, the HEI does away with for you.
Having done the engine recently, I might not be telling you anything but for anyone else reading..... welll... and, I haven't posted in like 6 months I don't think!

+2. It's the first thing I do with a new truck.

Good info here guys!

Jbesotes · 02-26-2010, 10:17 PM

Thanks for the info everyone, I did rebuild this motor about 5 years ago taking it down to the block and having it boiled and new pistons along with everything new from the crank to the velves, so it is still a new motor, and only has about maybe 20,000 miles on it.

I am going to look into that Edelbrock 500cfm.

Most any cam grinder makes cams for the GM I-6. Crane, Crower, Erson, Isky, and Schneider are a few that come to mind. Doug's, Hedman and Hooker make headers. All you gotta do is look around...

How will you set up the Carb linkage? I just install the Clifford Man with Edle Carb and now I am trying to figure out what to do about the Throttle Linkage. Lokar Cable?

I used a '71-'72 throttle cable set-up. I hacked it together quickly, so it ain't pretty, but it worked. What do they say? "There's nothing so permanent as a temporary solution".

Thanks, I know where there is a 71 at my local Junkyard, I dont see the Kick Down Cable, is yours Manual?

Yeah: 5-speed.

I used the whole '71 gas pedal assembly.
