Engine rebuild #2 present day !
So now we jump to present day. My #'s matching 350 engine with date coded Rochester 4BBL Dual exhaust, is in the shop. With what the assumption was that I only need to replace the Oil pump. I ordered a new Melling stock flow pump and pickup screen. Now the fun begins. motor pulled and I get a call from my builder Bob Blitz in Kennett Square PA. He says I have the motor out and you need to come down. Well so not to turn this into a post the size of War and Peace. I will list all the things we have found from the first rebuild over the past two months. Engine work started the 20th of June. Here is what was supossedly done, told to me back in 2007 1st rebuild. Cylinder bore 0.30 was actually 0.440 over.( now 0.60 over ) Hardened seats installed, NO hardened seats present. Wrong valve springs and bored for said valve springs, Bore was larger then speced for valve guides vs valve shafts. Bob had to custom make bronze guides for proper fitment of new valves, since the old valve shafts had improper ware. New 1970 0.60 deep dish pistons. New crank since the previous builder install the main crank bearings to tight to the crank journals,no oil bypass at the crank which also led to scoring in the cylinders. New Cam since the cam ended up with a chipped lobe. Luckily chip did not travel into the path of the push rod. Amazing that this engine stayed together for 13 years !
Bob blue printed the new engine and everything now synces up prefectly ! He knows his stuff with 50 plus years of experiance in racing engine building, and I trust him whole heartedly. He has taken his time and his attention to detail is unserpassed.
It doesen't bother me the lenght of time it is taking ETA end of August, since the Covid 19 situation has basically whipped out all car shows here in PA and tri state area.So I will wait patiently for my 9.5 to one compression 350 Rocket to return home
