I'm Awesome
To throw this sucker on the 383 while I have it apart changing lifters. Single plane with a 103mm TB. I have been considering 4.56s for a while too. I miss the snappy 5.13s I had in the 9.5 SF 14-bolt when I had the old 350 in the van. Honestly thinking of gearing it to make up for the low speed torque loss and letting it eat a bit. Cam and heads want to run to 6,200 rpm or more but it is currently choked by the marine intakes longer runners and vortec air hat at 5,500.
