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.
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.
1969 Pontiac GTO Open Hooker Headers
1969 Pontiac GTO with 461 stroker Hooker Super Comp headers and DMH cutouts
opened. See my other video of the same car running through the Flowmaster
mufflers. This vidoe is open Exhaust.
Going to add a Victor intake and 850 Demon carb next week. Should have some
track video next month.
