Received my engine in friday. Im storing at work until i can finish restoring all the misc parts and pieces i am transferring over.
Heres the engine all wrapped up
So according to the paperwork the block casting is 395558. I looked it up and its a 69-70 350
It has two different heads though according to paperwork
411929 - which is a “8” head from 73-76 and a 409147 which is either 7 or 7a from 71-72 based on what the internets tells me
I have unpacked and confirmed all the numbers yet i just peaked in there today to find the paperwork
Will my current intake that was on my 307 work with this engine for the time being?

Not sure I'd be cool with mismatched heads. You may never feel a difference -- just general principle for me.
Edit: I just looked it up and the 7 and 7a heads have 64cc chamber vs the 8's 79cc. That's potentially a huge difference in compression ratio from bank to bank. Any chance there is a compression test and oil pressure sheet in the crate? I'd definitely be calling the builder before I moved forward at all.

Not sure where the sbc 307 came from. The intake will work but will severely limit top end. I used the SP2P(tiny triangle ports)intake on an Olds 350. Part throttle was amazing but the Qjet overwhelmed it at full throttle. It would do nothing for a few seconds then catch up slowly. What is the big casting number on the shelf by the oil fill tube? With the #8 head and 24cc pistons, the only affordable cast pistons available will give 7 to 1 compression, 8 to 1 with a 7 head, maybe less for both, they sit way in the hole. Another early head would be a good idea. Most get 68 to 70cc for 7/6A heads stock. I have measured 77 to 78cc for the #8 heads. Honestly the #8 would need a .040" mill and a bowl hog under the exhaust valve to equal the 7 head. Edited after rereading it.
