does the 250 bolt in the same as a 230? i was thinking of switchin out my 230 with a 250 for more hp. but if the 250 doesnt bolt right in, i may just go to Clifford and sup. up my 230. does anyone have any suggestions or recommendations?

Hey Surfcat, You shouldn't have a problem. My
'65 came with a 230 and it has a 250 in it now. My old '64 had a '76 camero 6 banger in it[crap by the way, stay away from integral heads!], and it came with a 194. Some even came with a 4 banger, but I couln't tell ya about that. In fact, any one ever seen an early with one?

thanks Dan,
anyone eles? should i keep the 230 or get a 250? and,.. has anyone done this swap before?

Swapping in a 250 is easy. The 230, 250, and 194 are essentially the same engine as far as installation is concerned. If you haven't already done it, swap in an HEI distributor while you're at it. Getting rid of the breaker points ignition is nice. Things to think about are: stay away from the 250's with the integral heads. As already mentioned, they suck. Also, you may have to upgrade your radiator. At the very least, have your original radiator flushed and pressure tested by a reputable radiator shop. If you go with a souped-up 250, you may want to get a new radiator core with more rows. Aside from that, You can pretty much drop it right in.

I dropped in a 250 out of a `72 pick-up.
Also left on the p/u bell housing as it has an 11 inch clutch.
As far as the swap, everything (except carb) changed over.

If you really want to improve your I6 put in a 292! Some people are getting mad power out of em. Check out this site: www.inliners.org (http://www.inliners.org) a great site for the inline buff.

For what it's worth I had a 65 with the four banger (153) in high school. Also I was told the 292 is taller in the heads and would require a swap of the doghouse to the later model size.....

TurboVan (`65) had the 153-four in it when I bought it. I drove it that way for about a year. Terrible mileage, and if I revved it too high, the lifters would click something awful for a while. Also, top speed was 85MPH in third... or second... it didn't matter!

How can you tell if your 250 has integral heads or not?

03-01-2002, 09:50 PM
The head and manifold are all one piece.
We're talkin' LOW PERF.

Not to mention when those heads or manifolds crack a replacement is BIG bucks if you can find one.

thanks alot everyone, very helpful! what about cost wise? would it be less expensive to say, go to Clifford Performance and get what i need for my 230 or try and find a 230 thats been rebuilt?

You should check your local NAPA store for complete engine kits & they are reasonable.
Also check online at like PAW (Performance Automotive Warehouse), Summitt, & Jegs to name a few.

thanks greyfoxmc,
do any of these guys have websites?
being a mechanical no-brainer what would i ask for, just a 250 strait 6? do i get the 250 and then go to like, say, Clifford performance and get the extras there, or do they sell 250's all suped up? what about modified intake manifold, exhaust manifold or header, camshaft, connecting rod ratio, carburetor size and design, etc., etc., ??? all that stuff is like Japanese to me. Help!!!

Hey SC ....
Here`s the links...

Last year I bought a complete motor rebuild kit from NAPA for my `70 olds 455. It was $ 460.00 which I found resonable after some searching.

Good luck.... Mike

thanks again greyfoxmc!
i'll check 'em out.

ok,.. so i think i'm gonna get myself a 250. now the question is: should i get a new clutch pack as well? the clutch seem to be fine except for the fact that lately it has been starting to whine a lil' bit when i take off in 1st gear. is that a sign of wear on the clutch? and if i do get a new clutch pack, does anyone have any suggestions as to what kind i should get?
Thanks Bunch,

03-19-2002, 08:31 PM
Whining in first only? Sounds like you need more lube in the trans. Noise when the clutch is depressed is a throwout bearing. As far as clutch recommendations go, the ReMan units are fine behind a stock motor.

re-manufactured unit .... cheaper than newly manufactured.

ok, makes sense. (duh)

Well, I just solved my problem. I have had my 66 van for 10 years and have been back and forth.....keep the six or go to the trouble of installing a 350. I have been reading the good and the bad. I like my six, but nothing beats the sound of a Chevy V8. I just piched up a 1966 Chevy short bed step-side. It has an beautiful running 250 and three speed. I have a feeling that may changs. Oh and I will also have a spare 250 for the Van. Jack TWO66er`s
