NASCAR 351W's are bored to 355 cid, the maximum allowed, and make right at 750 hp. This with a single four barrel carb AND a restrictor plate!

Figure cost at about $75K per motor. It will turn close to 9000 rpm but this DRAMATICALLY shortens the life of the motor. Best keep it around 8000 or so. If you lucky you can get 500 miles out of it. Classic engine problem with these motors? Valve trouble. broken springs or the valve coming apart and tearing up the piston. These engines are built extremely "loose". The pistons barely fit the bore for instance. They are a motor "on the edge". Miss a shift and you will blow it up.

351W stroked/bored to 427 (which is the MAXIMUM you can go and NOT recommended by me) with a single four barrel, yeah I can see 750 hp there. How long it will "live" if you USE all that horse power is another question!

But it do look good!
