Are the heads deilled for accessory mounts... like what's in your car now? Is yes, just swap your stuff in. If no, then your 355 heads are early GM cast iron parts and might be worth enough as restoration bits to finance a good chunk of some better parts. BTW, I would never install an engine I did not help build without at least partial disassembly to see if it was put together correctly. Engine swaps are enough work that a gasket set and a weekend's work could be a wise investment.

Power steering doesn't bolt to the heads; it bolts to the block. Both blocks have the necessary mounting holes for PS.

GM started putting the lower mount holes on SB's in 1955. I can't recall ever seeing a Gen 1 SB without them. 4 holes, 3/8-USS thread. 2 on each side of the timing cover. Prior to 69, GM did not have any holes in the heads for accessory mounts.

Trivia tidbit- those lower holes in the SB were for engine mounts. They fall in the same location as the front mount on a Ford Flathead. The guy that worked for Ford and was part of the design team that did that had a funny name. Zora-Arkus Duntov.

I think you mean "camel hump" heads, unless you are refering to the small mountain in Scottsdale,AZ.

You should be able to add PS w/o an issue regardless of the heads on the engine.

The question that immediately comes to my mind is that if the guy that "built" the engine can't determine whether or not a bracket will bolt to the block, is he really up to building an engine worth having?

Update------Just went out to the garage and did some checking------I have a SB400 on a stand, the lower driver side holes (the ones that the p/s bracket is mounted to on my '73 350) were never drilled. Also have a 350 out of a '72 pickup (long water pump) that the p/s bracket is mounted to the water pump and the driver side exhaust manifold only. I guess it is possible to have a 327 block with no provisions for mounting the short water pump p/s bracket, anyone want to comment? I suppose to mount the Corvette p/s bracket you would have to drill and tap the block for the correct size bolts if you are hellbent on installing this engine into your '76. I tend to agree with Markids77's advice, considering the effort it takes for the average guy to do an engine swap, I would have to be pretty damn sure of the engine's quality.

If the bosses for the holes are there but not drilled, cast iron drills and taps very easily. 1 hour job unless it's in the car.
