OK current setup:
347 10:1 comp. track heat intake and 170 cc heads, 30# injectors, TFS 2 cam, 80 maf 75 TB,
BBK 1 5/8" short tube headers, into 2.5" non cat H pipe, into 2.5" flowmasters with no exaust pipes
made 351 RWHP at 5500 rpm
Upgrading the camshaft to a xfi236 ...and hoping with upgraded valve spring and retainers and headers with make in the 370's for RWHP at about 6100 rpm
question is:
1) Do I get a LT header with 2.5" collector and 2.5" x pipe and leave the 2.5" mufflers
2) LT Header with 3" collector, 3" x pipe and upgrade to 3" mac pro dumps
3)LT Header with 3" collector, 3" x pipe into a 2.5" reducer to the 2.5" flowmasters i currently have
Possibly adding spray later on for the strip...
What ya'll think?
