I am new to Buicks, but have done a lot of Olds and BB Chevy builds. On a 72 455, what mods would you recommend to have a strong and stretable combo. I would like to not change pistons. Thinking cam, heads, intake, headers. Thanks for your knowledge.
Upgrade cam, heads, intake and headers. Top it off with a MSD and a properly rebuilt Q Jet. Dont go to crazy with the cam selection. I think the 72 was like 8.5-1 compression. Finish with a 2500 stall converter.
Lots of people, myself included run high-mid 12's on stock low compression short blocks. Briz's advice will get you there...
