Wes is correct..Please save yourself a bunch of heartache and get some qualified engine man to go back thru your motor..it will be worth the extra money...MY gut is telling me that Bret Probably just thrown something together to get you half way off his back..
i went thru something simliar to this about 7 yrs ago..when i took off my valve covers and saw the valve springs shimmed up i was smart enough to have it torn down and gone back over..the reults were as follows..
wrongs size valves (length) had to purchase new valves and springs, 10 thousandth's PVC at full adjustment,rotating assemby was 2 oz off,(could not have been balanced)
wrist pins worn out,wrong length studs in bottom end. mains.. block was oringed and wire was out of place on two cylinders..which would have caused a head gasket to blow..
How was this list for SCREWED UP DEAL...and i am not making up one thing....if anything i left something out..
.My 'good engine" man that i had go back thru the motor said it might have started and idled but once i gassed it ,it would have grenaded...it cost me another $2700 to fix the mess..but would have cost me over 10k if i had fired it...
just thought i would share my experience with you,,so you may not feel soo bad.
and for the record i have always been pretty good at top end stuff..cam shaft up..since then if i have went with a new complete motor i will have the shortblock machined,balanced and i will do the rest...
My decision to do this was a REALIZATION THAT I COULD SCREW UP MY OWN STUFF FOR NOTHING,,SO WHY PAY SOMONE LIKE THE 1ST GUY TO DO IT FOR ME ?????.
i have been luckey so far not to screw up something to bad....just take time and ask plenty of questions along the way..
Good luck my friend my heart goes out to you and anyone else that has been had this way.
Brian
