5.4l liter engine is 330 cid.
4.6L engine is 281 cid.
350 - 351 engine is 5.8L
Facts: 281 cid engine has run 5.70s in the quarter with good heads and lots of boost
70 psi. 5.4L engine has made 1400 hp on the dyno with good heads.
351 engines with simple belt driven superchargers have made about 1000 hp and
have since the mid 1990s.
It has to do with the block strength and the other related rotating/reciprocating parts.
With good parts, no reason why your post would not be totally possible and a fun project.
If Charlie66 can make 800 on 206 cid, a good 300 cid engine could and has made over 1000 hp for many years.
Big cid engines are there for durability over the long haul.
That is why Pontiac engines, 389, 400, 421, 428, 455 were excellent high mileage
capable passenger car engines for many years. And most small Pontiac engines are
at least 326 cid or larger. So agree AIR RAM.
