If you are going to do this in a stock block don't waste money with a forged crank and heavy rods as the block will break before the crank and/or rods. The Mahle "PowerPak" pistons come with a nice ring package and are also budget friendly. Get the compression up to 10:1 - 10.5:1 and top it off with a decent set of heads, an Edelbrock Performer RPM dual plane intake with 750 Holley and you are 95% there... call Mark Chacon at Bullet Cams and have a custom cam ground and you will have your 450 hp without breaking the bank.
That’s fantastic info
Thank you for taking the time to lay that out.

What are your thoughts on spending the money on a Dart block when doing a 347?
My understanding is the block is the weak link and the upcharge for the Dart seems minor in the grand scheme
