You won’t be anywhere near competitive with a stock bottom end. You have to get the engine guide from NHRA and build it to that. You’ll probably need 8-10 head castings (with the correct casting numbers) to get a pair and a spare worth building.
To be competitive you’ll need hours and hours on the flow bench looking for .5 CFM anywhere you can get it, on the maximum allowed port volume of course.
Youll need to look at probably 6 or 7 different valve jobs and test them all, unless you pay someone who has made the castings you need Stock legal. Expect to pay through the nose for that.
You’ll need a modern, updated cam. A 10 year old cam won’t do it IF you want to be competitive.
Rings ain’t cheap.
By the time you start adding up, you’ll pay a lot of money to be competitive. Or you’ll spend less money and be a first round duck.
Stock Eliminator isn’t for the faint of heart.
