  • finally got it running

    i really dont post much here, but im always here watching. after 3 years i finally got my 3.4 running. P&P'ed irons and manifold, crane solid cam .493/.512 lift and 290*/300* advertised duration. 4.3 TB, stock manilogs and exhaust for now to pass emissions. break-in went well, needs tuning, i have to get the aldl cable to datalog but it fires right up and idles around 700 rpm.

      im thinking its because of all the backpressure from the stock exhaust. im going to un-cork it and see if it makes a difference
