buick GS 455 stage 1 first startup on engine stand

Description

This is the first startup of my 455 stage 1 after rebuild! It crashed few months ago :((. Exhausts on this teststand are the stock cast headers. carb is a beautyfull barry grant 850 demon on an edelbrock 455 performance intake. cam is a SP 1165R, 112LC. Later, we replaced it with a stock GS cam for smoother running. TA 1.65 red roller rockers. heads flowed and ported. SP/FM hypereutectic pistons. Kenne Bell valve covers. they look kinda cool, don't they? This should push around 390HP with the stock cam and around 430HP with the SP cam! runs like a baby :). listen!
