David Vizard bench flows a BBD 2bbl
Well there are two fairly common ways to raise compression, the 340 way or zero deck closed chamber way. All done before all proven. LA 318 heads are junk when you can use magnum heads. Just for the flow characteristics. All of these things have been done before, and those involved know the recipes. there is a reason the cylinder head guy is working on the 302 heads. The LA 318 stock heads will be tossed. If the stock LA head were to be used they would need positive deck height pistons. Last I checked they cost 1000 dollars or so.
Vizard will do his tricks but parts will be swapped...unless they do a dyno pull on video i wont believe anything Tony says as far as HP numbers. Hes a bullshitter with ET times he will be a bullshitter with HP specs.
