Thanks Allan... But being an Apache pilot with an hour of F16 time.... I might
even take on the Top Speed in the air..... and 228.304mph on the ground with a
hurt motor shut down.... I think the tach speed was into the 235mph range on a
230 record... oh well someday.....
Basically what I was trying to say was clean the things up.... but don't get
carried away.... it's easy to hurt port velocity .... that is Slow down the
speed at which the air/fuel mixture is entering the chamber.... that and it's
real easy to hurt the scavanging advantages of the exhaust if you over port
it..... This has alot to do with thing Valve overlap at TDC and we don't
really get into High Performance cams here....and NO I don't really want to
because to be honest I have used what worked for everyone else... IE the
Street Kent cam kit.... " and Yes I am very satisfied with it in a 1275" I
didn't go into the study of the LBC cam... it takes lots of time for me to
think all of it through.... to try and see where this guys numberes are better
or what he has compromised here or there to gain something else...

Keith is being way to modest here. I'm sure he has gone faster than any
other person on this list. (At least, he has in a car, on the ground.)
I was watching Hot Rod TV (on Speedvision, I think) and they did a 2 minute
demo of porting. I knew that it was much more involved than they showed,
and some dumb kid is going to rip the heads off his '79 Dodge pickup truck
next Saturday and start grinding away. When he puts it back together he'll
wonder why it runs so rough.
