Early vs late 67 430 - how do you tell'em apart?
Dear Team Buick members :shield:,
A Buick 430 V-8 . . . and it's mine - all mine! :1st:
I have successfully purchased a 430 that came out of a 1967 Buick Electra 225. I started to research rebuild kits for this engine and EGGE Machine Company has two different versions of their rebuild kit: Early 67 and 67-68 http://www.egge.com/kits?make=BUICK&year=1967. Kantor Auto on the other hand has a single kit for the 67 http://www.kanter.com///productdetai...at=31&Prc=1660. So reassuring when different aftermarket manufacturers provide "consistent" information about Buick engines. :confused:
Has anyone heard of a difference between 430 engines built in 1967? If so, how would I identify an early versus late 430? I haven't had a chance to inspect the engine, but will do so tomorrow so I can read-off casting numbers and that sort of good stuff like that.
Thanks for all the help from the Team Buick gurus! :thumbsup:
Cheers, Edouard
P.S. Should I go back to the donor car and get the data off of the builder plates. Is that info I'll need to have in order to care for the engine?
Block casting number is listed as 68-69: 1381825
Dear Steve, Paul, and other Team Buick members, :shield:
I'm back from my first careful look at my baby! :bgrin: Do I have baby pictures you ask? . . . of course! http://gallery.me.com/elagache#100036.
Here is a picture of the casting number: http://gallery.me.com/elagache/10003...12960669410001
I read this as 1381825. Checking the handy-dandy Big Block casting numbers list from Team Buick: http://www.teambuick.com/forums/view.php?pg=casting_numbers_big_block, it reads as a 68-69 casting. So I suppose this must be a late 67 430.
I assume from Paul's comments that this engine must use the straight rockers. Is there likely to be anything else that would be different if this is the 68-69 casting?
Thanks to all for your help as this engine swap caper unfolds!
Cheers, Edouard
Dr. Frankenbuick to the rescue again!
Thank you Steve for your elaboration!
Always feel better when Dr. Frankenbuick is on the case! :thumbsup:

I found in some reading that the later shaft/rocker assembly was stronger. You may be able to reuse your shafts and/or rockers depending on wear and cam selection.
I now have the number of the head casting: 1382985. However, it seems that further work on engine will be on hold as other features of this conversion caper are worked out.

Hmm, I must confess I have no idea what this means. :clonk: So in desperation, I grab the TA-Performance catalog and . . . ahh, rear sump oil pans. So I assume I can indeed purchase something from TA-Performance's generous offerings and that will get me unstuck from this one - right?
I thought I might launch a new thread once the rebuild actually gets started, but for now - I'll try not to hog Team-Buick too much more!
Thanks for all the help and for this forum that makes it all possible! :finish:
