With all the reading here about when, not if, your stock big block will crack the mains, cylinder walls, etc, I would like to know opinions about small block Chrysler engines. I have never had the opportunity to work with them. so here goes:

What is the best stock block to look for and how much can you safely make without worrying about hurting the block?

Are any aftermarket blocks available?

How big can you safely make a stock small block in cubic inches?

What are some good books to learn about small block Chryslers?

Thank you all, I am sure I left out some information.

I know very very little about small blocks because I'm mostly a Hemi guy. But I do know this: If I was going to ever run a small block, it would be a NASCAR engine. Those things are pretty cheap, readily available, and they definitely have got some snort!

In a LA stock block you can make 600hp no problem

I think Ritter is the only game for new race blocks. There are still a few X or R3 blocks that pop up from time to time. Expect to pay $4k or so for an unused one?
A 4.125" crank will get you better than 426 ci.
There is a ton of free info if you are willing to google it online, but the Larry Shepard books are pretty well regarded.

Thank you guys, I think a big inch small block would be a blast. I have read about the Ritter blocks and problems. Do you think the problems are behind them?

How fast are you looking to go and at what weight? A stock Small block will hold up to quite a bit.

Skip right over to the Hemi. You know you want to. If you're going to buy all LA stuff just don't. Start oiut with the new Hemi and even though it costs more it weighs less and has a much higher hp potential.

While I don't have one, it sounds like the Ritter blocks are ready for prime time.

However if I did get one, I would make sure it was a "latest version" and I would have a top notch machine shop check if fully before using it.
