it happens, that crank saw 7000 and a four-speed for over 5 decades. RIP.Even with another 318 crank won't it still need to get balanced?
If he finds another forged 318 crank he can likely get by without it.
I do the 360 in the truck is complete, i got it to run for a few seconds by pouring gas down the carb. I did replace the fuel pump on it because the one on there wasnt sucking any gas out the can I hooked up too it. When I removed the fuel pump i stuck my hand in to feel the timing chain and it has alot of slack. I was only going to use the 318 because I knew it ran in my car and everything looks fairly new. I also dont have space for a engine right now so which ever one I dont use I planned on selling real cheap or trading for something I can use rather then it sit outside and go too waste. Still not sure which direction too go really wasnt planning on taking it apart.
Sounds like you'll have to look into the 360 as well, replace a timing set and maybe oil pump while youre looking inside. Cracks are funny.. in that they grow at different rates.. and sometimes they arent the end of it at all.. and if you never saw it.. you may have never known and possibly never reaped the consequences. Hard to know.
Yeah I sure do, I just know once I open it up im gonna more then likely see something I dont like and its just gonna snow ball. Or if I just replace the chain and it end up having another issue down the road not sure how long this engine has been sitting. I do believe its the original engine has a factory four barrel intake and a 727 with the 9.25 rear with a sure grip. I think im just gonna pull it and try and sell or trade for what im needing. At least with the 318 once I take care of the crankshaft situation I think it'll be alright ran fine in the car and sounded pretty good. Not sure the specs on the cam but its not a big one. This truck is just gonna be a cruiser id like it too be a daily. I have a 73 d100 that has a 360 and thats the one I plan on trying to make power out of.
I might i do plan on trying to get it running again and at least idle. The way im looking at it is, do I take a chance on this 360 I know nothing about or do I use this 318 that I had running before and looks pretty fresh inside? Keep in mind I can care less about how much power this truck is going too make and at least with it being a 318 id less likely wanna do anything else too it. It really just comes down too which one i think would be the cheapest too go with. Id hate too get the 360 going and it have some type of valve or ring issue. And im kicking myself in the *** because I got rid of the 318 that was in better shape or let it set outside and it start too have issues as well. I have alot too think about, but I definitely dont plan on keeping that crank in it so as long as I can figure that out id proceed with the swap.
Yeah I might just do that i have all that stuff. I also believe my chances of trading or selling which ever one I dont use will definitely be greater if its the 360 then the 318. Alot of people are gonna say exactly what you are saying."No way in hell i'd run that 318 over a 360" i personally dont care because im not trying too make any power out of it. I can understand if I was then of course id be choosing the 360. I just want which ever one is in better shape and would more then likely have to not come out again or have excessive labor done too it. Im not set on the 318 either but I do believe its in better shape then the 360 thats the only reason im leaning towards it. Im gonna look into this crankshaft repair or replacement and go from there.
Thats how I found the crack, changing the pan and pickup.
The edelbrock rpm on my other 360 will be going on it.
Drill a small stop hole at end of crack after mag shows where end really is. Then clean & maybe silver solder to wick crack totally full. Heat must be right! And a large chunk of steel like that may make hard to do(or undoable)or need to be oven heated.
