I am going to be sending my head to Larry Cavanaugh and the cylinder block to pit stop performance very soon.
Can't wait to get this thing done.
Thanks

Thats pretty optimistic for a 1075 without a really good cylinder head/hot cams and a healthy set of carbs. :laugh:swest wrote: Over 100 to 125 ponies depending on how it's tuned. :woohoo:

In reality a stock kz1000 with a header and a stock set of 28s is probably putting right around 80 hp to the back wheel on a good day.swest wrote: The stock KZ 1000 was boasting of 91 BHP. The Z1 had 84 BHP at the crank shaft.

I think omr's 1st 1015 motor with the 10.5:1 wisecos a decent head done by larry and a set of cr's with more fine tuning/tweaking done than should probably be allowed by law on the carbs made around 95hp at the back wheel.
Id say that same combination with a 1075 kit would make between 100-105 at the rear wheel.

Yes it is. FSM numbers are about 15 HP off the real world, rear wheel numbers. A good fresh 1075 with everything else stock will run good if it's tuned properly but not 100HP at the wheel kind of good. Bottom line is you build what you can afford to build. Things are really getting expensive.

That will work. Will pull hard from about 5k on up. Those cams have a ton of overlap.

Go FedEx or UPS for shipping. Fedex Lite lets you print your own shipping label with a debit or credit card without having to sign up for an account. Their prices for USA shipping are very good also. Fedex Lite .
I have a new digital setup for my flowbench that your head will be tested with. Dave [OMR] and I have been working together on a new digital manometer for a little over a year now. I've been using on for the past couple of months now and we have others out there being give a test drive by other people. Blue Box
How's this for flow?

If we then factor out any marketing inflation, what actually gets to the pavement may be quite a bit less than advertised.
Then we could get into the whole eddy-current vs Dynojet argument..............
