All CHevelle, Tempast, Cutless, Skylark (and shared namplates)From 1964 to 1972 share the same brakes and chassis componants. I have in my 1965 Gran Sport: 1972 Olds Cutless disc brakes, '70 GS steering box, '70 GTO sway bars (front and rear), '70 Skylark 15x7" Road wheels with 225/65 Goodyear Eagles and Gas shocks. And I will tell you....this bugger handles!!! My wifes 1965 Skylark 300-4 has the same sway bars, gas shocks, and 1978 14x6" roadwheels with 215/65 Goodyears. And an HEI from a 70's 350 Buick. All Buick V8 HEIs will work, but you have to change the gear on a 455 dist., to fit. The manifold also needs some "relieving" for the HEI to fit. Look at a '74-'76 V6 to see what I mean. You also will need a button head allen bolt at the front of the manifold. <P>------------------<BR>buickfam@aol.com<BR>Life long Buick Fan.<BR>1965 Skylark H/T<BR>1965 Gran Sport Convertible<BR>1948 Chevy Pickup with 401 Buick.
