Inline help please!

I am having a 250, non intergrated head, I6 rebuilt and want to perk up the HP a little. Mostly looking for flat top pistons and possibly a small cam. The final plan is headers and a two barrell carb. I will also keep the three on the tree so this will be no real hot rod. Does anybody have part numbers for Pistons, Camshaft, Two Barrell Intake and headers? Also just as important is where to buy them.

You can use 307 pistons and there is more info at:

I built mine about 20 years ago from info that was in a hot rod book. It was quite the Frankenstein, using like 307 pistons the such..... This is the camshaft number 2291878, I forget the manufacture but I kept the sticker off the box..... just google it. My six popper runs great and has lot of torque and power, but still mild enough for just a daily driver. I ran a couple different 2 barrel carbs and just recently built the one barrel to put back on it.

Thanks for the quick info. Now it looks like I have a couple of more forums to get used to.

Sigshooter what exhause did you use? Also mosquitos are a blast to shoot.

http://www.inliners.org/tech/cams250.pdf is the link .. Take into account what gears you have and what you really what to use the engine for .....

There's all sorts of stuff you can do. HEI distributor helps out, I went with Pertronix for the stock look as well. 194 head is closed chamber so that ups the compression as well.
I put the Clifford 4 barrel with a 360 Holley Carb.
Clifford 3 into 1 headers into a Dynoflow X muffler, don't like the sound of it, I'm going to add two resonators.
I machined 1/4" off the back of a Nascar Harmonic small block balancer.
You can hear the sound of the six on the YouTube link.

I never got around to putting headers or 4bbl intake on. i ran stock ex and intake manifolds with a 2bbl adapter... single turbo muffler. Iam going back to a one bbl carb that I jetted up and keeping my stock exhaust manifold. going to try and regain the stock appearance

All good and correct info above.

For the first mild stage I agree with 307 pistons, HEI or Pertronix ignition, and a mild cam. another cam manufacturer to research in Schnieder Cams. I like their dual phase grinds.

the next stage would be bigger valves, install lumps in the intake ports, a small 4 bbl on an Offy intake, and headers or Langdons cast iron split exhaust.
