340 or 408?

Didn't mean to create this 8 page battle of testosterone , Literally just seeing if 500 hp is realistic in my street car and my options compared to a 360/408. I am looking at the 340 and if it it looks good I'll probably scoop it up. Maybe it's my downfall but again , I'm an old school guy whos ways are out dated but still work and I have a ton of fun driving my car and ripping some gears. Thank you to all who helped me and put their .02 in. Much appreciated!!

This is exactly what happens when bad orthodoxy is exposed.

Testosterone has nothing to do with it. It’s common sense engine building and most of the guys in here popping off aren’t engine builders.

Like I said to YOU in my first post. Do not lie to yourself about who YOU are. You can do 500 hp with a single 4 barrel and solid lifters.

It’s even easier with a small solid roller cam.

And at most it should be about 6800 rpm to do it.

If you want more stroke and less rpm find a 3.79 stroke crank. Turn it down to 2.100 rod throws, use a 6.125 Chevy rod and a 4 inch stroke piston.

You can use off the shelf parts for that. You will still be out of cylinder head sooner.

I’m going to use a 3.79 stroke deal but I’m going to use W2 heads. Otherwise I wouldn’t even do that.

And no matter what you decide, make sure you get the intake manifold ported. Putting an unported intake on a 3.313 stroke is a power killer. It’s even worse when the stroke gets longer.

Be honest with yourself and don’t let other people superimpose what they can’t or won’t do on you.

Just like my first post said.
