I'm working on a '79 *amaro for a friend. Its got a '68 327 and a set of "434" casting iron heads with 60 CC chambers. Assuming a .030" bore, flattop pistons w/ 4 valve reliefs, and a .045 head gasket, what would the comp ratio be?
We have no idea what shape this motor is in. It runs, but no idea of cranking or oil pressure. How hard is it to pull the oil pan on a 327 and have a look around?
Where are the numbers on a TH350 so I can ID/date the tranny?
Thanks
Chip

Pulling the pan with the engine in the car would be a major pita.

I can leave the front cover and stuff on, right? Sounds like stupid question time, but I've never pulled a pan on a SBC before.
Is it OK to unbolt a rod cap, examine the bearings and torque it back in place?
Thanks,

It was not a "huge" deal, but not a walk in the park, either. We had to undo and remove through bolts holding engine mounts together, then used a floor jack with a block of wood to carefully tip engine up off of it's mounts. Oh yeah, we also had to disconnect the exhaust pipes from the manifolds (that was the hard part). Once the engine was tipped up, we placed 2x4 blocks between the engine mount halves to hold engine up, undid oilpan bolts and dropped it onto crossmember. It JUST cleared coming down and towards the rear of the car. This might not work on a small block, because it's longer, but it's just a suggestion, and may give you a place to start. Wannabe

The pan comes off like a stovebolt.
You dont have to remove the timing cover. Removing a main and rod cap won't hurt anything as long as you keep it clean and put them back on the same way they came off. Make sure that they are torqued to spec.
