went and picked up the rad and pressure over flow tank today .

then motor/trans combo was ready at local ABF terminal .

next to the last parts order showed up today . just waiting on a clutch linkage piviot pin swivel .

hope to start tearing in to the stuff Thursday . going to reseal / clean the tranny first since he goes in first cause I don't have a med/heavy duty style tranny jack .

then it will be clean / reseal the engine and get ready for drop in .

dam used motor is junk . . . . . tore in to it to clean and re gasket / seal it and the carb throttle shaft was frozen ( 1st oh sh!t ) then trail of water down intake runner ( 2nd oh sh!t ) and pull plugs and #1 solid rust ( 3rd oh sh!t ) and bore scope down plug hole has shown SOLID RUST and NO FU*KING GOOD AT ALL ! ! !

then to top it off the head guy in charge has just left yesterday on a 2 week vacation out of the country . so I have to wait on a refund on my credit card . . . .

Send your original motor to the machine shop for re-bore and have the heads reworked. You will then have a new motor that is dependable.

I don't think its even going to take that . . .

pulled a valve cover and you can basicly eat off the inside of it . my buddy bore scoped the plug holes and all but 1 super clean . 1 has tinyest bit of powdered surface rust in 1 spot.

Friday its hanging on a engine stand and tearin the heads off . were going to find out the rest of the story as paul Harvey would say .

Amazon has a set of 8 pistons .030 or .060 oversize for $265.00. If you have a good block you can overhaul these fairly reasonable. Even if your bores are good, a new set of pistons will go a long way given you have new ring lands and you don't have to clean up the old pistons.

I just had a 427 rebuilt -the engine kit was about $1050.00 included pistons,,rings,bearings,timing set,oil pump,cam and lifters and gaskets.Machine work-bore .030,polish crankshaft,plane heads,valve job,and assembly was about $1075.00 . So about $2200.00 total this should give you some comparison for what a total rebuild will be.
