In a word. Nope. I bet that thing has 8.5:1 compression with those flat tops and 68cc heads. Unless they're ported AFR's or something really special, I don't think so.

:rotfl::rotfl:400HP 305 huh..:rotfl::rotfl:
With stock, large chamber heads?:rolleyes:

Look at the Edelbrock crate engines and you'll get an idea of what it takes to get 400 HP.:yes:

Quite a bit more cubic inches (and compression I'd bet:yes:), better heads and a larger cam just nets 425 HP....

Ok, nuff said.... I'll let you draw your own conclusions.

I dont see that making 400 hp either.

Just for BS sake I have see 305s with about .60 over with flat tops, non-ported stock valve size heads in mid 50 cc range a stock intake and a Qjet make over 500 hp with a stock lift hyd cam and stamped rockers.


Of course these are not cheap and they are very labor intensive, but its very impressive to me to see a combination like that make that kind of power.

So I guess if that 305 mas massaged a bit in both labor and parts 400 hp is possible, but why? It would be far wiser in my opinion unless you are for some reason required to have a 305 to build something else?

I thought it sounded fishy...but I am a huge noob when it comes to engines and what it takes to get power. Thanks for the input guys.
