  • Where'd you get the cam? And what springs and pushrod length did you go with? BTW I'm in Belton, wouldn't mind seeing that goat in person.

  • @Kalinder24

    The cam is from Vengeance Racing, spec'd to be midrange for the size of the motor. The heads are trickflow 225s, so they are the springs that come pre-built.  The pushrod length I can't remember anymore, they are a bit longer than stock I believe to work with the trickflow heads.

  • Serious question: What kind of milage does the 408 get. I am curious because I have a 6.0 and it does good on the Highway, and am considering doing a stroker, but if its a lot worse I might not. thanks

  • @kx250ltr450

    Not very good MPG, it averages about 10 mpg. On the highway only it averages 17-18 though.

  • 1 7/8' headers, 3" collectors.

    The exhaust is 2.5" SLP LM 1.

  • Is the exhaust really coming outta the stock location? lol

  • Yes, the car has no cutouts or dumps.  The camera was pretty good, and picked up sound well.

see all

  • Just curious, has it been fully tuned yet? Also, how and/or where did you get it tuned? I'm from the 254 area and was hoping I could find someone or some place that would hook be up with the bobcat 455 tune for a reasonable price. TIA

  • sounds sick as fuck. i need to get some more cash so i can build mine more

  • Dude really mandulles. But nice car my friends gto also is sick
