1967 GTO Kanata Cruise July 24
A very fine example of a '67 GTO, 461 stroker (400), four speed car with
American Racing wheels and 3" Exhaust
all the way back. Built by Dave Stoddard in Ottawa.
Sehr Performance Machine / Lane's 468 Pontiac.wmv
This is a 400 Pontiac stroked to 468. Lane had some work done elsewhere on
this engine in the past and was not happy with the outcome so he brought it
to Sehr to get it done right. Lane did it the right way, he has a really
good bottom end on it with Eagle stroker crank and Eagle full floating "H"
beam rods so he has plenty of reserve to build on.

Bear's GTO - Pontiac 461 - First Run.
First run of the engine my son Ben and I built for my 69 Pontiac GTO. This
is the original 400 that came in the car when it rolled off the assembly
line in Arlington Texas. It's now a 461 thanks to a 4.250" stroker crank
and an .035 overbore.
The First time my 400 Big Block got started.
