heath,
i'm using 38mm chokes.........manifold is 38mm and ports are about 38mm as
well. 44mm inlet valves - 35mm exh valves. i suppose the trumpets are 4
inches long - and i'm only using sock filters (not blocked !!!)
i'm putting it on a dyno for a tune check up / mixture check next
week. i don't know, that might be restricting it a bit........... but let me
tell you...... 17 miles per gallon is about the average consumption !!!!
so, after that, i'm lost........everything is done......... i spoke to ivan
tighe cams and asked if the 76 deg works cam is too big - considering that
they work up to about 8500 and mine only revs to 6500. the feedback i received
was if i put a 72 or 74 deg cam in, it would struggle to reach even 6500. so i
guess it needs the long duration to rev hard.
i'm not really in the market for 48s - as my 45s are nearly new.
dunc.

valves & ports, free flowing exhaust, 76 works cam....... it's got
everything that should make it rev...... however 6500 is it.......no more.
mind you the torque from about 2300 is strong and they are easy to drive
around town.

preffered engine to make high RPM horsepower. i think the rod/stroke ratio is
around 1.75:1.........

running BIG boost)
