**600hp sbm block limit? Or is it bs!!**

If you want to be a serious racer you want a 408 that makes less than 550 or go Ritter and be a Superstar Racer!
I agree. A stock block is fine for much of what street and street strip guys do. If you want to drag race a stock block, I see no issue with a stock block up to a certain point. That’s what this thread was really about from my point of view & of course the actual question proposed by the threads title.

You can certainly race a stock block. It’s just not going to be in a heads up category where extreme power levels are required. While 600hp maybe extreme for some, it’s still 2000 hp short of serious heads up racing.

The old known fact that some people seem to refuse to follow is the lighter the car the easier it is to go fact isn’t followed. Im still meeting people with small block powered fully loaded B Body cars telling me they’re upset for not getting into the 9’s. They skip the facts and advice.

While I do think 600hp ought to get you going really very well, you have to at some point start thinking about what it is exactly you have and the goal line you are trying to cross. Where this line is, I don’t know. But I went out and picked up a race block.

Then there is also not just the amount but frequency, there is the severity amount of its use.

If you like to cruise your car and talk about your car to all your friends then by all means build a 600+ hp LA. I did back in 2008-9. 408 with a Procharger and a TKO. It made 650 hp and 598 lbft. I fell into the "cruise and look cool"
Bad *** build my man.
You want to take a stock block to high horsepower levels then you have to cross every t.
Cross every “T” & dot every “I” for sure. Then again, same for a racing engine.
