Is this engine builder nuts?

If you need 350 hp there's easier, possibly, cheaper ways to get it.

If you just want a snappy teener, for a streeter, adjust your expectations. 275 crank horsepower in a lightweight A-body can be a ton-O-fun! This is just a lil cam, a small 4bbl, and a free-flowing exhaust, with headers.A little head work, and it can be a lil more funner. Don't forget; if you match your powerband to your tranny,and optimize the combo, you will get the most out of it that she is able to give.

X2 from the times I have driven my car with that ^ setup aside from headers and head work it has been a blast.
