X2 that seems like alot more cam than i would expect for those goals. I would have guess well over 600 hp and higher rpm with those heads and that cam. Maybe with a good single plane.

I had a 400” with 246/252 on a 113 lsa turbo setup and it idled mean but was very driveable. 108 lsa and more duration should sound very tough

Wrong again, you’re making an issue where there is none. Knight has clearly stated all the correct engine parameters were entered. The “289” is a information block for the printout, nothing more.

Since you’re on here claiming the dyno test was inaccurate, Please tell us, what is your dyno experience, training and qualifications?

I question that that disp:289 input is info only.
I bet it does refer to the engines cid, thus effects calcs for corrected horsepower readout.
Should be disp:414
I still like the build combo.

Idled at 1100rpm with over 10" of vac, rorty idle, but clean & stable - not really an 'in car' assessment yet, but that's what it was like on the dyno.

Here's uncorrected #'s & air conditions:

Nice work Tony, that will liven the hq up. One brother with a HQ 414 chev, one with an XR blown 302w, both probably on the road around the same time! Should be some good old brotherly races coming up im sure! Fun times.
