Hi all I built a 350 2 years ago and it has ran good. It was my first motor I've done,i pulled the heads and my quench is at 64 which i think is horrible. I'm trying to bring this down so here is my stats, 350 bored 40 over 10cc dish pistons Stock stroke Vortech heads 64cc redone for 525 lift Stock deck hight Voodoo 268 cam 3:73 posi 2700 stall Th 350 I wanted to bring my squish to 40 but it seems i will get compression up to 10.1 if i do. This is a weekend driver so running 93 octane is ok.could this work with iron heads??
With the dished pistons, you CR will probably be BELOW 9:1. The only way to change your quench now, is to use a steel shim head gasket, or have the block decked (assuming you keep the same pistons). But, as long as you don't get detonation, you should be fine as is. You can always try retarding the timing, or stepping up to a higher octane fuel first. Butch/56sedandelivery.
