burnnotice1000 588 Posted April 28, 2022 Yes it's the same sump,I'm stokedSent from my SM-A125F using TapatalkDoing a lot of research on the 429 cj/scj and they are a very rare engine these days ,as prices for these original factory parts are crazy even in the USA,heads are near non existence to buy I guess that's why so many just build a 460 with spruced up 460 heads so I had another look at my 73 heads and turns out they are the last of the decent ones to play with at 91 cc chamber anything after these are 97cc and if you can find early castings they have even smaller 70 odd cc size these are starting to look good my new valves should lob up next week.Sent from my SM-A125F using Tapatalk 2 1 gerg, Outback Jack and deankxf reacted to this Share this post Link to post Share on other sites
CHESTNUTXE 7,332 Posted April 28, 2022 also i read last night that my sump needs a police/cobra jet oil pump and pick up,as a std one has the wrong angle to fit,there is about 10 million different pumps and pick ups for the big block ,sumps as well. 3 gerg, Outback Jack and burnnotice1000 reacted to this Share this post Link to post Share on other sites

Is it still ok?I would do the valve guides, if they're sloppy they'll flog the seats out and also cause oil consumption. For the little extra, it's worth doing right.Sent from my CPH2197 using Tapatalk 1 burnnotice1000 reacted to this Share this post Link to post Share on other sites

I'm using std clevo spring and retainer as I thought the 460 uses the same ? For std factory set upSent from my SM-A125F using Tapatalk Share this post Link to post Share on other sites

bear351c 10,273 Posted April 30, 2022 There should be a little gap, on single groove valves. The multi groove don't have the gap so the valve can rotate. 3 Outback Jack, gerg and burnnotice1000 reacted to this Share this post Link to post Share on other sites

CHESTNUTXE 7,332 Posted May 4, 2022 there is also good news on the heads,olm8 is machining them and cutting the seats to seal better,he did just 1 seat while i was there and the difference was incredible from what they were. 3 1 deankxf, burnnotice1000, Outback Jack and 1 other reacted to this Share this post Link to post Share on other sites

CHESTNUTXE 7,332 Posted May 4, 2022 you mean the valve stem or seats ? as it was they are untouched from new he reckons and still ok to use there is very little if any wobble from side to side,but the seats just needed a spruce up,being a 1973 or 74 engine its possible this is a unleaded engine ,i think they started using or introduced it in 1971 ?. 2 burnnotice1000 and Outback Jack reacted to this Share this post Link to post Share on other sites

I was lucky when I got mine done up, someone had done inserts before.
