[67 455 Bird ragtop]

After many years waiting the next step in getting my 67 Firebird back on the road happened last month. Initial startup of my motor. Sounded great. But will need to wait until Monday for full break in and a few pulls to get a good power reading. But it started.

Here are the basic specs - 455 +.060 full 4 bolt main
74cc KRE d-port heads flowed to 310 cfm
Edelbrock Performer RPM
H-O-Racing TRW L2359F pistons dished 16cc
Forged SCAT H-beam rods bushed for floating pins
Comp Cam 305-AH-8 cam 108* LSA 253/260 @.050 duration .577/.594 lift w/1.65 rockers

Was happy with the initial numbers. Oil on the dipstick was nice and clear. I'll check the oil filter contents later. We only did two pulls with no timing or tuning changes. Carb might have been a little undersized. So with the EFI and timing control I think they should get better. Peak torque was 593 @ 4100. But what was nice was the logger started at 3000 and torque was already at 536. HP was 528 at 5100. Not too bad for a nice cruiser. Can't wait to get the car paint and on the road. Cal Hartline will do the tuning when ready. Fortunately he just lives down the street and has a chassis dyno in his garage.
