I have a 305 sbc in a 76 monte carlo. It has sr torquer heads with a he252 crane cam and a spreadbore holly on a 300-38 holly intake and headers. The engine works well, hard to beleive its a 305. I've read a couple of mr vizards books, were I've read on the heads and the latest on the cast iron intake. On a 350, not much can take on the cast iron intake below 3000rpm and on a 283 or a 305 that may be as high as 4000rpm. My engines peek torque is about 3500 with it falling on its face about 5000, The heads and cam dictate that. My question is, Would I be better off getting a cast iron intake, and taking off the 300-38 holley intake. The 300-38 is old school, some say its a copy of the cast iron intake. Or is there another intake that will work in a range of off idle to 4800rpm. My car is big with 308 gears and 3900 lbs. Any suggestions here would be helpfull.
