LT4 Hotcam Results 1989 ZF 6 speed
Read so many posts on so many setups so thought I would share mine.
1989 L98, family owned since new, 42,000 miles. Bad head gasket caused a complete rebuild, professionally built 355
Set-up:
Ported TPIS style ported 113 heads
Edlebrock intake, runners
LT-4 Hotcam with 1.6 RR
Running a Moates Emulator
After market exhaust with front cars eliminated
Stock headers
Stock throttle body
24lbs Bosch 3's
TPIS dyno and tuned
248 rwhp
Forgot wheel torque but equates to a little over 400 ft lbs
Real numbers for you guys to ponder....
