both are fine quality, the below numbers are the high side and low side of the dimensions, the first is the rod journal on the crank, the second is the housing bore of the rods with no bearing. I dont know if you have a bore gauge though

2.0990-2.100
2.2247-2.2257

How was the thrust bearing? Is this a stick or auto?

kaggriff

I do have a bore gauge. thanks for the specs

it is a stick. and to be honest i really didnt pay much attention to the thrust bearing dont recall seeing one but i will look hard at it this evening.

kaggriff

ok so now that i feel like an idiot, I did look at the thrust bearing. I was actually thinking about a toyota engine that has thrust washers. which I deal with toyota everyday.

It has wear on the back side with little to no wear on the front side. ANd good call on the crank as it is an eagle crank. shows what little the engine builder really knew. I did mic the journals and rods everything is within spec and there is little runout on the roundsness of the rods. pretty sure now that the wear is soley due to detonation/timing issues.

So tomorrow I will check the piston and block as it about has to be slap. Guess I may have to start with a different block. Thanks for you help Woodsy!!!

woodsy

Check it with a tq plate or a head bolted on, IF it was honed with a plate originally. If it was, and you dont replicate a plate or head, the readings will be skewed dramatically

I think i will leave checking the block to the machine shop. not sure i trust my skills that well. and really dont want the same issue when i go back together.

kaggriff

well block and pistons are all well within specs. but after looking at head it appears there is possible some coil binding going on. so I need specs for the trick flow stage2 cam and what spings they recommend. with lift specs we can check curent springs for bind. thanks for any and all help.

trying to due this one time and one time only. find it and fix it right the first time.
