I have a 1984 Hurst Olds Cutlass, all original numbers matching car, I've ahd it since I was 14 and have only driven it once, witch was around 5 years ago, but have been trying to get it going again for the past month for some reason sitting for the past 5 years the engine no longer wants to turn over, it is locked tight. I've filled the cylinders with penertrating oil and allowed it to sit days at a a time inbetween trying to get it turn over, I've resorted to placing a breaker bar and socket on the harmonic balancer still with no progress. I'm to the point I'm about ready to snatch the original 307 h/o for something else. Which I haven't decided LT1 or LS1 have crossed my mine but really dont want to go that route any ideas on how to free this block? if I opted to go the LSx route how would I go about bolting it up to the 200r4 transmission?

Hmnn how good of condition is it in? For some reason those seem to have a lot more collector value then the same body 442. It will always be worth the most usually by a good margin on the market to keep it original. But if she has rust and needs paint stripes etc etc then it makes it more sensable to to just build what you want as opposed to restoreing it. Plus the 307 is just no fun and not worth the money to try to make it fun. IF its rough and you are not going to restore it but rather mod it then I like the idea of the LS motor. Forget the LT1 not that its a bad motor but when you are starting with a clean slate. I would consider restifying it. Meaning stock looking but not stock internally. In that case I would do a 400HP pump gas 403 as it is dimentionally identicle on the outside to the 307. Check out www.jsmachineoldsmobile.com/home.html
Give it to me!
What about an Olds 455? I do like the LS idea though. Just keep it lookin stock on the outside, with a fun motor on the inside.

spent a few hours today playing with it still with no luck of freeing it up...but did make note that my 200r4 does have a universal bellhousing, which was a plus....
first i'd pull the plugs, then the valve covers and loosen the rockers (this way you're not trying to move the lifters) then try and rotate the engine backwards. if that works try tightening up the rockers again and see if it'll move the lifters.
the LS series engine will bolt up but there are a couple of issues. one of the bolthole won't be used and, i forget the specifics, the torque converter snout is at a different depth. there is a fix for this but i can't remember it right now.
luckily the LS engines are getting to be dirt cheap from the junkyards, just make sure to get the ECU, wiring, MAF and other sensors, and air ducting.
