1972 Javelin SST engine swap ?'s

My pops has a 304 with in edelbrock intake, ede 600 carb,hooker headers,etc.  I put different bearings and a little bigger comp cam in it a few years ago.  The heads were redone (the shop didn't put harden seats in) ever since it has been using oil.   

He doesn't really care how fast it is. He had a 360 in his 74 amx and it was plenty for him.

Thanks for the info.

To answer your questions, which to me look like you are trying to "re-use" the intake, carb, headers, cam from your 304 on the 360, exact fit, no problems...you don't care about the heads inside....keep the 360 intact.  A 78 will direct fit your 72 Javelin, the trans will work too....but all 360's from 1972 up in passenger cars did come with a 727 Trans.....maybe do one thing at a time, if out of a 78 Jeep, then you will need a Flex plate to bolt the torqueflight in and you need to remove the "sleeve" in the bore of the crankshaft, that is there on Jeep's with Turbo 400's behind the engine, it will come right out....if you don't remove it the torque converter snout will not engage the crankshaft.  If you just bolt the 360 up to your existing 998 trans, the driveshaft is fine, if you upgrade the trans to 360, make sure you get the transmission yoke, 727 is larger.  Then just get your original driveshaft shortened and balanced with new yoke and u-joints.....you are back in business.  Speedometer cable and kick down/feed back linkage will all direct swap.

(known issues with 360's) If I do purchase it I plan on just checking the bearings (replacing if needed)<span style="white-space:pre">     </span> swapping cams and installing a new timing chain.  I believe the 304 has a petronix electronic ignition upgrade hopefully reuse it. replace water pump  the transmission shifts ok but reading not so great reviews on the 998  Ive got a spare tf2 shift kit for a 727/904 will it work in the 998? maybe hold out for a motor and trans assembly then I would only have to deal with the driveshaft.  how much better is the 401 over the 360? thanks for all the help

If you are still inquiring about the 727. The differences between 401 and 360, is that the 401 727 has better performance parts already included. I think a bolt in sprag Is the only big option to boost it's hp rating above 600 hp. But I would recommend a good rebuild when installing the sprag.

As for blocks, they are both dependable and capable with mods. If you can find a 401 at a good price jump on it. But for the money a 360 with some mods can be easier found and more money friendly, and give you almost the same power as a stock 401.
