Used my buddys dyno yesterday - heres some cam numbers
Some people were asking me my gains from the TR230 and 243 heads
60hp and 15ft/lbs at the rears from a cam upgrade. I switched from the stock 241 head to a brand new set of Z06 243 heads when I did the cam.
The car had a different mail order tune for both before cam and after cam. I believ both dyno charts to be "corrected"

Mail order tune
Everything else stock

Something's screwy w/ the graph...the HP line is above the 400 mark nearly the whole way across the test range, but your numeric "Max Power" shows <400hp?

that seems pretty good, any reason why you guys took it to 6500rpm seems kind of high.
I saw the first graph and was thinknig that is kind of low for a cam, but i failed at reading. lol

You're reading it wrong. The top lines are torque and the torque numbers are on the right side of the graph.
Edit: My question is, why doesn't the horsepower and torque cross at 5250 in the second graph?

IS this the 230/236 cam or the reverse split 230/224 cam?

The TQ scaling is off. If the scaling on the that graph was equal for both HP & TQ, they'ed both cross at 5252.

To me it looks like all the power was gained after 5000 rpms. Would a Steaper Gear ratio help with get to his power band faster? Say like a 4.10? Lookes like from 3k-5k its pretty much spot on with his bolt on dyno for the HP. Me personally I dont care about Peak hp. I want to see gains thoughout the power band. What was the A/F during the run?
