bracket to stocker

[jmoneyfoot]

I m looking for some help and input. Im turning my bracket car which is a 77 buick skylark with bbc, powerglide, 12 bolt into a stocker. My car came with many engine options but were can I find out which combinations it had? I know it came with a chevy 305 but im not sure on specs. What are rules on engine casting # and head casting #? The nhra classification is really confusing. Id like to know what motor I can run, carb, transmission, rear end. How do I find this out? Im new to this so any help would be great.

First thing you'll want to do is go here and sign up :http://www.classracerinfo.com/

Then come back here with your specific questions.

12 bolt at the original width would be legal.
Any GM 3 speed automatic that bolts to engine used, would be legal.

Best tip is to buy Tim Lowe's Buick stocker...see classified section (assuming he still has it) Super fast car and you'll invest that much to even get close to where Tim's car is. See link...

This is a perfect example from another thread.
Where a Buick 455 or 400 or 350 from another year would bolt in.
And fit into existing classification guide.

Looks like the 305 is nhra rated at 180hp and would be a natural R/SA
