what type of compression with a slightly domed piston should I expect to have, with a TA 284 -88H cam with 460 in 460 exh.?
To avoid any guessing, you need to know: block deck height bore chamber volume piston volume (+ or -) gasket volume (or gasket bore and compressed thickness) Most Buicks don't need anything but flat tops to get upwards of 12:1 static compression with the decent iron heads. the '74 & up heads had huge open chambers that are not well suited for a high performance aplication. Camshaft profile has no bearing on static compression ratio. Dynamic ratio is another story, but you need the above answers to take the first steps. Devon
