Newbie Header Exhaust Question
Hey Guys! I'm new to the board, but an old uneducated car guy. I used to throw parts on my engines and just live with the output. I am now trying to be a little smarter. I have been reading all of the 307 chevy stuff and plan on rebuilding the original 307 in my 68 C10. I plan to warm it up just a little (305 HO heads, cam, holley 600, Z28 intake, etc.) I believe I should use a small long tube header, correct? What about exhaust, 2.5 or 2.25? I plan on using a flowmaster type mufflers, we used to call them turbo mufflers, maybe an outdated term. I am going to turn them down in front of the rear axle. Will one or two of you gurus point me in the right direction? I hope this info has not been posted to death, if so point me to a link. I love the board so far!
