Well things never go according to plan, and even then the best laid plans never survive contact with the enemy... My plan being to refresh the engine with new bearings and a hone to the crank and cylinders.
After mic'ing the crank, it was discovered that the PO had already honed .030" off the journals and there would not be enough meat left to machine them again. Bye bye V07 Crank 😞
Hmmm, doesn't look bad but....
So where do we go from there? Reg looked carefully at the pistons and the ring chamfers and concluded they were beyond hope too. More sad news but oh well. What else could go south? Well, apparently the block was maxed out at 90mm and there was not enough left to hone reliably for new 90mm pistons and rings. 😞 😞
My sad pistons and rings.
Now what?? No crank, no pistons, no block and an E88 head with a corroded water jacket in need of a valve job and welding... After careful consideration, I decided I was not left with a lot of choice. Stay stock or start over. I decided to order a Dave Rebello 3.0 kit. Offset ground L28 crank, 88.5mm forged pistons, H beam rods, bearings, head gasket and rings. But where to put it? Lucky for me my builder had a stock F54 waiting for a future build in house. I convinced him to part ways with it, so that will be going out for some machining and prep for the Stroker kit. The E88 head was salvageable, but needed work to make it 100% again, so rather than re-use the E88, I decided now or never and brought my stock P90 to him for a 5 angle valve job, complete porting and polishing and custom fitting to the new block. Effectively the stroker engine will be all new with just the original valve cover and oil pan... New timing chain, cam shaft, valves, rockers, and paint.
My stock state P90
The plan is to have all of this arrive in time for Reg to assemble and have ready for me to install in June when I am home. So much for the low budget rebuild!
A nice pristine modded P90 from Reg...
