"That was a nice little motor, if I remember correctly you went a 10.80 in your Bird."
Thanks. It was a street combo and never spent much time at the track with that engine. It ran a best of 10.88 at 124.28 mph with a Performer RPM intake. One popular mph/hp calculator suggests 591.63 hp at that mph, my actual dyno sheet indicated 580.2 hp at 5800 rpm with the Performer RPM intake. With the Victor intake it made 600.9 hp at 6000 rpm but we never took it to the strip with the Victor installed.
A fwiw. Years ago a good friend built a simple street engine using a 4.250" stoke in a 400 block with 6.8" rods and 'cleaned up' 87cc Edelbrock heads that my engine builder put together, nothing special about 300 cfm and 10.3 compression. He used a Performer RPM intake, Holley 750 carb and 1-7/8" headers. The cam was a Crower 236 degree hydraulic flat tappet with 1.6 rockers. On the dyno it made 509-513 hp at 5200 rpm.
I believe this is the Car Craft article Gach mentioned:
That article brought a lot of controversy at the time. Many in the iron d-port small intake runner volume crowd refused to believe it made that power with a XE 230 degree flat tappet cam.
