Richie lots of us here have started with passenger car blocks. Yes they are more expensive. Personally I have used passenger car blocks for 15 years. Racing blocks could have lasted that long and longer (racing blocks are made from harder material so your ring seal will last longer). I assume you will be racing for more years like most of us.
-4 bolt caps-$300
-4 bolt ARP bolts-$50
-line hone-$200
-Dart SHP block (can be bought cheaper than Jegs or Summit)-$1500

so
$1500 minus $550 is $950. $950 over 10 years is $95/year. It is an investment you will not regret,

PS we have been using a 2 bolt BBC block in SS for years without failure.

Block would need line bore and line hone with cap change. Makes that aftermarket block look better.

Put a set of ARP main studs in it and let it run.

If you have already spent a bunch on your production block, you might consider using main studs, and main cap straps. I have a 10 yr use block, with them on it.
