I am having my 87 GT 331 stroker motor being built by S&B RACING ENGINES out of florida, and have heard different opinions on compression and cylinder head intake runner size. I know everyone has an opinion so please if you can give recommendation based on your knowlegde and not what you hear is appreciated. GUTS of motor are forged rods, forged crank, ross pistons, It was recommended to stay around 10:1 compression with a 185, 195CC intake runner AFR HEAD(possibly Dart) ,Motor will see occasional nitrous(is lower compression better? and why such a big intake runner head? to get the flow an AFR 185 puts out? builder stated motor will be 10 1/2 :1 and wants to use 210CC intake runner aluminum cylinder head, output between 420-450HP. Is bigger better??
