ported out tpi open headers lt4 hotcam
this is a standard bore 350 with 305 heads with 194 valves installed. lt4 hotcam with 1.5 rockers giving it a 494 lift.
1989 Firebird Formula 350 fresh custom L98, GMMG exhaust and more.
This is how my car now sounds 5-10-09. Just installed a new 355 L98 with 10.5:1, AFR Eliminators, Lloyd Elliot cam (223 230 .535 .535 109LSA) and a TPIS Miniram. Just installed a new McLeod clutch, "Dyno Don" headers and y pipe, and a fresh rebuild on my 9 bolt rear including new bearings, posi cones, and 4.11 gears. This car is not tuned, hence the crap out of the Exhaust. I was not able to get video of the Dyno runs but the numbers were 370rwhp @ 6200rpm and 350rwtq at 4800 rpm. Not too bad for now :-D
