I am hoping the OP will check and post the information on the engine pad.
That will tell us if the engine is a 348 or a 409.
348 engine codes started with F, G, or H (except truck 348 engines which were T, U, or Y)
409 engines codes started with I, J, or Q.
The engine front pad would be something like
T05I8QB (as an example - this is a 62-64 409 2x4bbl, manual trans, in a passenger car)

Just a 409 update, I spoke to my cousin that ran a 409 in his 55 chevy drag car for 8 years prior to upgrading to the 454 block.
He stated the 409 with solid lifters ran out of air due to small head intake ports at 7,500 RPM but said it was a good and durable design.
He ran his until the later big blocks came out with more inches and better heads forcing him to upgrade.
I was due for training on this. I always thought the 348 and 409's were boat anchors.
He also confirmed the right hand dip stick is a 348 engine.

Yes, with basically a flat cylinder head surface, area for valves was somewhat restricted although the head/block surface was slanted to create a bit of wedge effect. Chevy did a pretty good job compensating for these drawbacks and mechanical lifter 409s Chevrolets are pretty awesome cars - wouldn't mind having one.

Since we are on the 409 subject, here are my garage partners 409 (482 CU) cars in action. Buzzing through the traps at 7800 rpm

Get a 409 option window sheet made up and take it to NCRS meets! Sounds like a lot of fun!

I don't think anyone in this thread mentioned this, but the VIN itself does not have any indicating code as to the engine option for any C2. If the car were an L89, it would need to have proof in some other way (like confirming the engine block, paperwork, period pictures, etc.)
