Put a CHEV in it!
paint it Matte,
Call it a RATROD.

just kiddin.

Most anything "can" fit. But of course some "fit" easier than others. I had a 351W in a 34 ford and could still close the bonnets. took some considerable cutting of the firewall. I now have a small block chev in a 30 ford, this was considerably easier. It almost seemed like the block was more "rounded" It seemed to clear things really well and make for a more enjoyable struggle. It could have just been that I planned alot better and made a whole lot more measurements with the chev.
I prefer the chev. That being said....A whole lot of people took notice of the little '351 whinger' under the bonnet, its almost like they had never seen one before....go figure.
