95 k1500 with a 355 10.25:1 with speedmaster 195 alu. heads, and a comp xe274 with 1.6 rockers .519/.522.
Issue im having is i had an edelbrock carb on it and had nothing but issues and it finnaly crapped out on me the other week. Put a holley 650 mechanical secondary on it and it now idles and runs fine up to about 5000rpm. After that it acts like a natural rev limiter, i know its not valve float, but im pretty stumped with it right now. carb is jetted as close i can tell to what i need with 69/75 jets and a 6.5 pv timing is at 18* at idle and 34* total all in by 3500rpm. 3/8 fuel line from tank to carb with a bypass regulator set at 6.5 psi with the stock tbi pump. Was told combo should make around 400hp/tq
