I'm in the same place as you, except I curently run an all iron 302 EFI in my Autokraft Mk IV. I'm hoping the weights will be within 10% and the distribution will be maintained. The decision to go all aluminium FE wasn't taken lightly and so far I've waited a painful 18 months while the saga of foundry issues has continued. Seemingly that's solved now. It's not been an easy wait as I'm in the UK and have relied on emails and faith....!

The (well known) builder says the new units from Robert are the best he's seen. He says the machining has been done, the assembly balanced and hopefully next week the heads will be on.
The big decision is the cam. I want to race idle but be able to drive the thing on street. I'm trying not to interfere, because Mr builder says he understands, I can't have it all ways and to leave it to him. However, it's hard to resist looking at cam specs, once you know the cam sound you like (Crower 16331/16257)!

I'm happy to share what I've learnt, but as I say it's mid build right now. However, I think it will be worth the wait and everyone here thinks I'm insane to cut up a complete car to make it fit.
Thanks a bunch for sharing. My last engine, the 428 FE, was built relatively mild. My thinking was A, to feel 1966 and B, reliability. The reliability went out the window with a poor build. But I must say that a mild 428 was a powerhouse in the Cobra. And that was one in the 400 HP range.
You are going to love going from a SB to BB. It will be well worth it> I guess I am still holding back some on HP, but 500 is still a 100 HP bump!
Keep me posted on how your progresses.
