But this is cool, heck it would still be cool if it was a G3 Hemi, I've actually seen some good work done on those swaps to the older Mopars.
Heck, I was droolin' over a 1970 Challenger with a V10 from a totaled Viper at a car show years ago. Modified a little of course, he said he got it to push about 570HP while still using the stock Viper wiring harness tuned. Yes he said he knows he can push a lot more HP out of it but he likes it the way it is.
LOL my dad said the same when I told him it had a GM tps, iac, temp sensor, and ls coils haha. In all fairness the way HCR does their harness you can literally swap between sbc, bbc, sbf, any hemi etc in 2 minutes. There’s a sub harness that branches off for ignition that’s already pinned for your different reference voltages. You buy another sub harness, plug it in and you’re good to go.
