Re: 302 bolt on help
That's a good question, he hasn't said what you've asked. Myself.....270+ at the engine is plenty but it does make you wonder just how much they fudged on the hp numbers back in the 60's-70's. There are better heads out there these days if you want to make the big power, never owned a set of aluminum heads just worked over stockers.
Of course there Dyno's weren't as good as they are now either.
