If I was building a chev BBC, I wouldn't use any 396,402,427 cranks these days because there isn't much choice in pistons of those ch------------(based on stock/low hp, street engines)

The 454 core stuff is much more available and the parts supply is unlimited-----(I think I am down to only 5 more 454 mark 4 blocks)

For a street engine today, you can pay for a roller set up or you can replace what ever you build flat tappet next winter as you do it over---
I am about 30 or so engines in line here and I think they all are roller--except foe a couple fifties flatheads and a Ford Y-block

Pat--is all the snow melted?????????
