My beloved Lilly, 1971 145, has received a new cylinder head that was heavily modified by a local Volvo guru. Thanks to a dear friend who sold me the head for a fraction of what it's worth, all the quick and reliable knowledge from the Brickboard, and my supportive family, I am now driving Lilly. I had a blast doing the change over and it went remarkably smooth.
Went for the first real drive today and was happy to feel the car pull hard right past 90mph in 4th gear...yipppeeee.
The next step is to dump the junk Weber and install the SU's I bought last summer at the IPD swap meet. They appear to be in great shape so I think I'll bolt them up and see how well they will tune....

So now I would love to hear all of your expert opinions on horse power estimates as my wife thinks I'm too conservative and I think she is too liberal (with the hp that is :) So here is a run down of what I have done to the motor over the last 14 years of ownership:
Rebuilt, stock crank and connecting rods
.30 over pistons
Cylinder head bigger valves, heavily ported, double springs....Dennis can you add more detail/specs here??
Steel timing gears
Header with 2.5" exhaust
Down draft Weber tuned ~ok~ soon to be replaced by the duel SU's
Full crane electronic ignition including multispark discharge box and powerful PS91 coil.
Iskky street performance cam

And your best estimate is.....

Thanks everyone,
especially you Dennis :))
