Hahaha I already posted it in the swap thread and the “What did you do this weekend” thread hoping the owner is on here. Guess you’re sub’d to PFI also.Haven't finished the video so I don't know what it makes, but looks like it is in 2wd. I would hope around 225whp? Could be interesting to those considering a swap.
Yeah, I couldn’t wait and skimmed through to see the results. I’m surprised it’s that low in 2wd. I know mine sure feels like it has more than that.
Only thing I can think of is the elevation they’re at. They’re at 5,200ft. I was hoping they would unhook from the stock airbox for a run. I’ve never ran mine not hooked to the stock airbox.Yeah 162whp and 201ft/lbs. my stock truck before rebuild was 133awhp and 186ft/lbs and after the rebuild and exhaust upgrade was 145awhp and 194ft/lbs.
Good thing you can get an LS in the junkyard for $1500 and they bolt in, in a weekend.

That friend of their’s Phong has an 80. I’ve been waiting to see if he did/does any of the crazy stuff he does to it. He’s real creative.Yeah that would be about 10% loss from where I dyno'd so that would help! But it is also 2wd. We need to have someone drive a stock truck over to PFI's. lol
If your comparing a v8 vs a 1fz, you need to use the same shop dyno otherwise the compared numbers will be way off. Each shop's dyno reads different, usually by quite a bit. Tire size AFAIK throws off the dyno numbers too. If they brought in a 1fz powered 80 with the same size tires on the same dyno, then that would be a valid comparison. A stock 5.3 makes about 270hp stock at the crank. With a quality aftermarket tune on the stock engine it makes about 315-330hp and like 380 torque.
Way off is a stretch, that truck has 35's just like all the trucks compared to it. Realistically no matter how you slice it a stock 5.3 swap really only makes 25-35whp more than a stock 1FZ.
Same size tires is only part of the equation. You have to use the same shop dyno with the same size tires(and axle gears), and same transmission gear to have a legit comparison. Each shop's dyno can give way different numbers compared to another shops dyno. I'm not trying to make a case for a LS swap or not because that's a long discussion. Their are a fair amount of dyno shops in Colorado. We have a lot of awd cars and awd jeeps and chevys around here, so their are a lot of awd dyno shops. The numbers I hear are all over the place. But if you have dyno graphs of a 5.3 and a 1fz on the same dyno, that is a legit comparison with dyno sheets right next to each other. Another benefit to doing thst also to be considered (at least for me)when choosing a engine and or modifications is the overall power curves and the rpm range. Maybe your right on the 25-35hp with a oem tune, but you have to test it correctly to find out.Way off is a stretch, that truck has 35's just like all the trucks compared to it.
