If it's always 8 lines after the start line, then go ahead and read a record of 8 lines when you detect start, and then process them as a group:

if ($line1 =~ m/^Start/) {
    # Append the rest of the record
    $line1 .= <LOGFILE> for 1..7;
}

If you care only about the first and last lines, though, you could just skip the intervening lines:

if ($line1 =~ m/^Start/) {
    # Skip to the end of the record
    my $t = <LOGFILE> for 1..6;
    my $lastline = <LOGFILE>;
}

However, if you simply chomp your input line for the start record, you'll get the single line you want. Note: Some people (myself included) find it more convenient to remove all whitespace from the end of lines using $line =~ s/\s+$//; or equivalent.
