Day 1 on the Dyno is done!
Tested 3 cams, 2 intakes and 2 carbs.
Put another rumor to rest.
Offy intake will not perform better than a Clifford. I know this will raise some eyebrows, but it is true. Tested a 390 4 bbl, Truck headers, 1.84 lump head and Clifford 264 hyd cam with both intakes. Clifford produced more tq across the entire RPM range( 2500-5600).
Here are some #'s so far.
Cam 2 Mild street cam 240hp @ 5000 274 tq @ 3800
Cam 3 moderate street cam Offy 252hp @ 5000 278 tq 4100
Cam 3 " " Clifford 269 hp 5500 283 tq 4400
Cam 4 Moderate street cam Cliff 280 hp 5900 283 tq @ 4100
Next goes on a bigger 1.94 valved head, expect more power. Then test the weber intake, the turbo setup and a divided port intake/ head. Lots more fun to go! And no burns.
Have 5 more cams to test. 2 that are bigger solid lift units. Expect to see rpms to 7000.
Will run a few times after work this week and next Sat and Sun if needed. Tom
