This is an excerpt from a Pat Downs post today on the CLF concerning a customer's engine:
"I built him a 78x94 with a set of the new wedge port cnc heads. I
used our 2289 cam that is just like a 86C. He had some Scat 1.4
rockers that came out as a true 1.4. Also he sent me some 48 IDF
weber carbs. Compression was 10-1. I ran the engine with a 1-7/8
merged header. Horsepower was
5500-189
6000-195
6500-198
7000-200
It was over 100 degrees outside and our dyno room was well above
that. I wanted to do some lower RPM pulls but decided to wait until
the morning when it was cooler. I am really pleased with the H-P
numbers and I think this head is going to work out well."
These are the new CB Performance CNC wedge ported heads; a pair are going on my 2,387. They would probably be a good idea on any 2 liter performance type 1 engine. Note that cooler ambient temperatures and a little tuning will probably increase the BHP readings. An eleven horsepower "spread" over a range of 1,500 RPM on top is hard to beat.
