230 inline six

I've only owned chevys with V8s until I recently purchased a 66 chevyvan. I justify the new toy by telling myself it will be useful to haul and store swap-meet goodies to and fro. This treasure is amazingly original with the orig. 230 ci.six. I'd like to give it a good punch since it has a tight bottom end. Does anyone have speed resources, and-or advice to mild cam,carb,intake,exhaust upgrades?

Try inliners.org..It is devoted to the inline as well there are several folks here that do the inlne deal..

On a van like that and the propsed use I would go for a torquey kind of cam and probably just leave the intake the way it is and give it a real good tuneup.. those 6cyl work very well that way..

You would probably get a lot more answers if one of the Mods moved this to the Engine forum.....this is the Tranny and Rearend forum.

Tom Langdon's Stovebolt Engine company http://www.stoveboltengineco.com/index1.htm
is another good source of parts as well as information. I just got a set of his cast iron split manifolds. I'll post pics in my journal when the exhaust system is finished.

I am moving this from the transmission forum to engine section.

Good luck with your project.

I'm a cylinder head guy in a race engine shop In the 70s-early 80's we built alot of 250 sixes for dirt oval late model racing. They changed to V8s in the 80s.
I used use bigger valves,removed the head bolt posts and fill the floors and raised the roof of the intake ports. That was all for higher RPMs.
For the street here are my thoughts in the order that I'd do them.
If your 230 short block is OK you can use it. Later if you want to stay with the six banger and want more torque find a 250 or 292 short block. freshen it up and put your good head and parts onto the fresh short block. 230s and 250s are the same size outside. 292 have a taller block.
Exhaust: header or split C.I. manifold "Y"ed into a 2 1/4" -2 1/2"turbo muffler and full length system.
Head: good valve job,stock size valves, round sharp edges off of the short turn radius of ports.
Cam: Stock 250/292 cam or small RV/torque type
Ignition: later model stock GM HEI.
Intake manifold: Stock is OK. Offenhauser is OK .Clifford is too big
Carb: Stock is OK or Small Rochester 2GC ( 1 7/16" throttle blades) 500 cfm Holley is too big.
Wow it's easy to spend other peoples money.
Have fun,Smokey

The only things you need to convert a 230 to a 250 is a crank and some pistons. Like Smokey said, it's a good move when it's time to open it up.

Great info Yekoms; I won't dispute anything I've heard here but I have one concern. Since the bore of the 230 is the same as the 250 and 292 wouldn't the comparison be similar to a sb302, 327 or 350? I already know the answer to this, my point is I'd like to run this van only on the street but want an even powerband from idle to say 5k. I have more fun with the punch of a short stroke, well tuned sb so I'm pretty sure the 230 without any flow restrictions and a well prepped head with 194/150 valves and maybe a 224/480 cam could gain the effect I'm after. Y'all have posted great links for aftermarket parts and I appreciate all opinions also.

That's a pretty big cam you're looking at. I don't believe you'll have any power below 2000 rpms. 6s benefit from higher lift for the street. What about Comp Cam's 260H? That has a power rating from 1000-5000 rpm. http://www.compperformancegroupstore...ry_Code=61-CAM
Crane offers a cam with a little more duration on the exhaust side but a higher lift.

street engine= build for torque.

mild cam, 2.25 exhaust, route some ducting to get cooler air to the carb, stuff like that. I'd also change diff and trans fluid/filter if you don't know when it was done last.

Yep, I know what you mean. I like 327s with Power Pack 1.84"/1.5" with Duntov cams better than 350's. They make a good snappy 300 hp in a street toy with stick shift. Automatics I like more stroke. My only concern with the 230 is the weight of a van. Gear it to accelerate maybe it's tounge will be hangin' out goin' down the hiway.
I haven't mess with them in a six but the 1.840" (305ci) would be a good valve size. 1.94"/1.5" would be the biggest that I would use for sure.
In the other post I said that a 500 Holley would be to big. I was talking about a 2bbl. 500cfm 2 bbl wouldn't be to good at part throttle. A little 4bbl just may be pretty good. By the rules we had to use 2bbls. So I'm not sure about the 4bbl. It sounds like you are on the right track. I can't believe that nobody has told you to put the good ole' boring 350ci/350 Turbo in it yet.
Have a good one,Smokey

You have a couple of choices for the intake. Some will say Clifford is better and others will say Offenhauser is better. Whatever you choose make sure you can plumb coolant lines to it. Without heat your intake will allow the gas to puddle at the bottom of the intake causing it to run rough and blow smoke. I'm going to run a Holley 390 cfm 4bbl on my 194. I've also heard good things about Edelbrock's 500 cfm AFB.

Just want to add that this 1st gen. van weighs in at a flyweight 3600lbs (relitively speaking), and I'm rowing the orig. 3 spd. man. with what feels like 3:55 rear cogs.
