hi pres oil pump
blah blah blah

109.9 @ 6364
103.5 lbft @ 5076
This was with old filters and no trumpets.
I now have 50mm trumpets so will be interested to see if it tops 110

And dave it was running 38 degs max ignition which they said was probably a couple too high.

That's sneaky, you didn't say it was +90

[mk1matt]

It used to have an alloy rocker cover too but i couldn't handle the power

[Graham]

thats a good un ,

at that power output and with a fairly mild cam i wouldn't expect a big difference from the trumpets but you've got to try, a well moded head with Mex/Gt valve sizes should add 5-10bhp more

When my brother had his x/flow it was same spec with a stg 3 head and it had 120bhp. So your on the right track there.
