Hey man are you sure about the Stage II heads? Buick never made exhaust to fit the Stage II heads. You had to run tube headers. At the time Buick set you up with a set of the old Mickey Thompson headers if you bough th Stage II heads.Originally posted by mcollinstn
A friend has a sweet '70 GSX Stage I car. Red w/black in and black vinyl top. Automatic w/streetable converter.
Stage II heads, cam, cast factory headers, holley, msd, line lock. Several rear ratios to choose (I think a 4.10 is in it now). Factory sport wheels. Gorgeous.
I have a 71 GS455 in pieces that hopefully will be the subject of some winter attention now that the boat survived a summer
Also have a 70 GS clone that will one day get the aluminum TA Stage II heads I have and be a strip car.
