[55reasons]

From what I have dug up so far, a factory assembled Toyota 5.7 with a factory warrantied TRD supercharger makes:

507 hp @ 488 lbs used for about $3,500.

A crate Vortec Supercharged Chevy 350 with aluminum heads in stock trim weighs in at:

383 hp @ 511 lbs new for about $5,500.

My calculations are as follows:

Toyota: 507 hp @ $7.00 per hp.
Chevy: 383 hp @ $14.50 per hp.

Not trying to stir up a hornets nest, but I'm interested in some opinions on this. I genuinely dismissed the Toyota V8 idea based on comments that it would be too heavy and expensive. From what I can tell just surfing the internet, I was either fed bad info, or I'm comparing apples and oranges.

507 hp from a 488lb V8 for less than a supercharged crate 350 sounds to good to be true.

**edit** ....also stumbled across a website that specializes in adapting 6 speed manual transmissions to the Tundra 5.7... Somebody better talk me out of the tree!
