13's are a pretty good head. One of the best D-Port heads.
If its a matched complete engine , would be a 350hp from a 1970 GTO/Fbird /GrandPrix
Either a YS or XH block code

Exh manifolds look good too !

Well I didn't luck out on the block. No YS or XH I got a YD (probably grandmas grocery getter ) But when I got it the block had been bored .30 over and had new flat top pistons a reground crank new bearings , oil pump and cam and timing chain. Not sure what the cam was. The 13 heads were rebuilt and looked new. All I had to do was install gaskets and finish it out. I guess the good thing is I only paid 400.00 for it. The exhaust manifolds I bought used. There supposed to be RAIII manifolds.
