New kid on the block

[FATAL]

Hello everyone, I'm new to this site. I've just been given a 1975 CB750F1 by a mate who works overseas and hasn't the time to sort it. It has been stood in his damp garage for the last 9 years or so as the chain snapped and cracked the crankcase (happened to my K6 back in1978).
I have previously owned two K6's and an F2, albeit about 20years ago. I currently ride a BMW R1150GS and a Harley 1200 Sportster. I have taken this F1 on as a restoration project, with a view to riding it for a few years. I have done several BMW restorations, and a BSA, but this is my first Honda. I intend to get the bike within as near original spec as reasonably possible, but concours is not for me. I like to use stainless steel fasteners, goodrich type hose, and decent aftermarket shocks.
I am aware that David Silver Spares is a good source for parts as is the Dutch company CMS, can anyone reccommend any others in the UK, and are there any bike breakers about who specialise in old Hondas?
What would be a fair price be for a replacement engine as I'm not certain a rebuild is a practical proposition on this bike?

Welcome,
            Nice to hear of someone bringing another CB750 back to life, I'm currently rebuilding my 1976F1, it has sat in my garage for 12 years while I was working overseas, it's a bit heartbreaking as it was roadworthy when I left in 1994.
I get parts either from CMS, David Silver spares, or from eBay, just got a load of F1 bits in a job lot from eBay, also this weekend I'm taking delivery of a top end from an F2 (I've got one as well).
Engines do come up on eBay, recently there was one from a K series with 12k on the clock, I cannot remember what it eventually went for but it started out as

Thanks Spitfire. Today I've found someone fairly local who has a K8 engine with 20K miles and a few other bits as well, He wants

Try again my post went missing !
If you are happy paying that price then go for it, I would if I was searching for an engine. Have worked on K1, K2, F1 and F2 and have not noticed any difference in the frame mounts, so the K8 should be OK in your frame. The K8 however had different carbs from the F1, are these included with the engine, if not I should imagine the F1 carbs will be OK maybe need re jetting.

Cheers
