Engine Decoding 86 GMC - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I was wondering if someone could give me a hand. I have been on 73-87.com and through my books I have and can not figure out which engine is in my truck. It is a 5.0L truck and 305 style manifolds. What has me questioning is there is NO bolt in the P/S very rear exhaust manifold hole(at fire wall). If I remember correctly 305 manifolds won't fit 350's for this reason.

Anyway....here is the information off the P/S block by the head.

TO823CEJ OR TC823CEJ

180101264 OR 18C101264

I cleaned it off and you can read it but it is hard to tell the c from the o.

Thanks in advance for any assistance because I have searched and came up 0!
