finishing the new upgrades.... current setup 9 to1 , comp 260H/.. 212@.050 and .440 lift set at 106.5 ICL , DUI ,large log with mild port 1.75 Intake 1.38 exhaust upgraded valve train 302 short springs 1 piece retainers etc.,, Offy tri power, weber 34 ICHs, Clifford dual outlet header, 3 NX piranha Foggers 75HP. built C/4 with 2,200 stall converter in the works now.... plans are to add 1.48 or 1.50 exhaust with a street/strip port on a flow bench, head studs and 1.6 rockers.... motor made good power to 5,200 before not wanting to turn more than 5,200 to 5,400 but think there is more power with the head upgrades especially with the Nitrous now......any thoughts? I had read before where some went with a 1.47/.48 exhaust valve to minimize shrouding. plus will the 1.6 rockers added lift help take advantage of the larger valve and port work? also will be pumping up the compression to 9.5/9.6 to 1.
