New intake and wham, bam, thank you Mr. Camshaft
Finally got around to installing a cam more suited to how I'm going to use this engine. Specs are 260/272 .660"/.629" 112+3. Pairing that with these nicely ported TFS 245s, 13.5:1 SCR, and my new to me single plane race intake and throttle body from Holley, I'm confident this thing is good for somewhere in the 560 llamathrust (700 horsepower) area.
- EFI single plane split-design race intake manifold. Fits all GM LS Gen III or IV engines equipped with LS1/LS2/LS6 style cathedral port cylinder heads
