The 230 Headerfold project

[Jason Mills]

Chris,

Good information, thank you. I may be on my own regarding adjusting the timing/distributor.. but you gave me enough to start playing around.. and I will measure the head floor and see if I can some up with an intelligent numer, and report back.

The vent hole in the top of the head bottoms out at about 1.50 below the surface. the head is 1.80 thick.. so the materal at that spot is .30; I then checked other spots that I could look at. (the coolant transfer holes, spark plug, and inside the coolant outlet neck) all seem to be about the same.. I'm glad you suggested it Chris, as I was starting to get nervious about taking any more off with the grinder, yet I wanted to touch up a couple of the chambers around the intake valves..

Can I mount the 2BBL carter that I got from the salvage yard, on to this new intake manifold presently in construction, sideways?

That is, in sted of having the fuel inlet pointing forward, I would like to mount it so that it points to the side of the truck. will that cause problems with the float level, when going up or down hill? My reasoning is that that it might help distrubution by having the throttle bores running along the lenght of the intake manifold rather than sideways...

Floats are universally to the front, with jets to the rear. This keeps fuel flowing into the jets on hills and under acceleration.

Hmmm, I wonder if circle track racers mount their carbs with inlet to left?

If sideways, on a steep incline, the floats might not float. leading to more flooding?

Better to mount inlet forward.

Linkage was a PITA. I had to build a Z-bar to get the stock linkage to work on the wrong side of the carb. Then I remembered that on my '83 conversion I had welded a lever on the right end of the carb shaft, making hook-up to the stock PW linkage a breeze.

I just found a pair of BBDs that I have been sitting on since they were spares in '83. Lots to experiment with...

Thanks Chris,

I will have to figure out how to get the two venturis to feed into the intake manifold some how.. and point the carb forward. I might use your idea of working off the right hand of the carb, to get the linkage to fit.. but that is after finding a way to mount it with out ruining the airflow..

I made it out to the Dyno Shop in Santee this week. Talked to Mark about turning my BBD around backwards. Seems there's carbs with floats on the front, on the back, and on the sides. Holley 4bbls have one in front, and one in back, and on dual quad manifolds are mounted sideways. So I guess running the BBD bardwacks ought to work OK too.

That all said, I'll be turning my BBD around backwards, just to get better linkage approach. Plus building a better plenum on my headerfold project, rather than the adapter from BBD to 1bbl flange.

I also did some metal spinning this week- just an aluminum air filter housing for my air compressor. I'm going to try it for making velocity stack sort of blend from plenum to tubes. And maybe a steel sphere from the wrought iron fence supply as a plenum chamber too. Very spacey/organic?

I vote spacey....= )
Post a picture when you're completed!

I've finally put up an Imageevent site for my '53 FFPW, here's the link <http://imageevent.com/bigchriscase/exhaustheadersandintakemanifold>

You might also want to check my other albums from there, more mods done to the truck, including making it the only five window extended cab flat fender, the 5WFFPW.
