@ skeet-Im going with the 373 becuase they are coming with the tru trac for a steal. I currently have the stockers 342's in now. I would like to go FI but I want to put my saving to a 66-67 Chevy II. I might have a deal on a true 66 SS Chevy II, the guy doesnt want to sell it but I think he will. It needs work but what doesn from that year? Its going to be a daily driver with extra hp, gas milage is not that important as I live in Baytown and work off of Fairmont. The heads are getting ported, thats the last thing he has to do before install. Where can I get a 4" tube from? Should the exhuast be duals with an x or will the ory be fine? The reason for the FAST intake is the article that GM high tech put out with a 5.3 and made some good numbers.
Appreciate all the help and input.
Nbs= 78mm
nnbs= 80mm Is that the only difference skeet?
