Subject: Re: Flow numbers for the armchair racer in all of us by biggrizzly on 2011/3/25 23:05:21 I think that Jerry Jackson is fairly conservative when he is building a street engine for a customer. I have seen guys here with a lot more lift and more overlap but I think this combination will be smooth running and easy for Mick to create a tune. He did improve the flow characteristics of the heads from what I got from LE. Probably the difference between a LE2 and LE3 port job. I'll tell you.... I paid for that little bit of improvement!!! Flow at .550 lift went from a baseline of 258 to 270 and from 262 at .600 lift to 271 Of course this is all on paper. Also the bigger valves and the de-shrouding of the valves gave those improvements. |
