Chevy's latest V8 crate engine can handle boost of up to 15 psi. That means you can take this V8 and either supercharge or turbocharge it. Chevy says the curve below was from its LSX 376B15 engine without boost running 87 octane fuel. 450 ft-lb of torque and about 420 HP before you breathe on it.

Chevy says the engine started with the "...LS steel Bowtie standard-deck block, added a forged-steel crankshaft, forged rods, and forged pistons, then topped off the short-block assembly with high-flow, rectangular-port LSX-LS3 six-bolt aluminum heads for supercharged and turbocharged combinations." The $9,875 crate engine arrives without an intake manifold and no accessories. You built it up. For more information check out Chevy's infomercial on the engine. How would this short-block with a blower do in your dream build?

siamese bores...

junk.

 

short lived addiction fantasy and left aching like a hangover in the end.

 

I'd keep it to 600cfm and carbed.

 

 

the mythical non-siamese 1996 305 would do 15 pounds of boost for 400k miles. Now that is an engine.

 

joking aside.. once upon a time big blocks highlight was the non-siamese spacing for stamina. Big coolant sytems, big everything.Giant cfm for workload for many hours. It was a truck engine at first.

 

if they want real tradition and opinions strengthened..they need to base it on the real engineering.

I joke of the 305, a friend found by accident a space between the bores digging something out with a coat hanger. Funny enough us poor boys, it ended up the favorite engines long after the 350s died.

 

today..we got pitter pattering around 5 liters as the only options for reality. That was darn smart by gm.
