It seems that you all agree on shorter stroke for BBC engines so you can get a decent length rod in it. Is there a point where shorter strokes...
I have a Mark IV iron 9.800 BBC.
I was considering dropping to 3.766" to keep the piston speed down and the cylinder wall happy. Might still go that route.
Ya. I'm trying to get by on a relatively small budget which is why I was questioning the girdle. We're not pushing it too hard - 1100 to 1200 hp.

I'm either gonna build a 3.76" or 4.00" stroke BBC to run with my 12-71 Littlefield. Any suggestions on header/collector size? I just bought what...

Newbie here. I'm building my first blown alcohol engine. It's going into a full tube '68 Biscayne. I currently have a 12-71 Littlefield with an...
