Guest Anonymous Posted March 17, 2002 Share Posted March 17, 2002 I am building a 305 for now and im using vortec heads and a rpm airgap manifold with a 274 450 crane cam i know its a little overkill for the 305 but im building a stroker bottom I just want to get a v8 in there for know and i dont feel like buying everything again when i go 383. My ? is about the heads they are centerbolts off a 305 and i know little about valve size,cc and how well the flow? if anyone can help i would appreciate it!

Mike C Posted March 17, 2002 Share Posted March 17, 2002 Are the heads Vortec 305s or regular TBI 305 heads? Quote Link to comment Share on other sites More sharing options...
Mike C Posted March 18, 2002 Share Posted March 18, 2002 The Vortec has a tall skinny intake port, but the 305 ones have 58cc chambers which is too much for most 350" motors. Get the casting number and go to www.mortec.com Quote Link to comment Share on other sites More sharing options...
