Im a little disappointed that an LT1 cant take much boost, compared to a coyote. Kinda wish I went with a ZL1 instead of my SS 1LE but now the MSRPs seem to have jumped by a lot over the last two years, plus it will be next to impossible to get one now.

I'm at 12 lbs and likely over 750 whp now on the stock pistons and rods. Wouldn't say that's only a little bit of power, and I beat this thing pretty hard.

Apparently stock 5.0s can’t take that much more I believe 750ish is where they start to have big issues

Coyotes need billet oil pump gears over 750whp the last I researched them...maybe that has changed? Have you seen what it takes to change them? Coyotes are only cheaper to mod right up to the point you have to tear into one. Then it's an arm and a leg. And they don't run 8's for long on stock trans and short block. Most that own them very long end up fully built if making big power.

Not what I’m seeing with the Gen3 Coyote that got rolled out in 2018. I researched the hell out of it before buying one. Lot of guys in the 9’s and some in the 8’s with a stock shortblock. Can you have one screw up at that level? Of course.

Oil pump gear replacement seems to more for the guys running 2 steps to launch. Banging off the limiter a lot seems to be more of the issue with the oil pump gears, not a horsepower level thing. There’s a ton to love about the coyote (stock cams to 2000 HP, port and direct injection from the factory, OEM wideband with WOT fueling trim, etc) but there’s no such thing as a free lunch. Eventually if you keep modding, we all have to pay the piper.

Does anyone else feel like a Blower isnt worth it on stock internalsfor an SS/lt1

depends on the goals for the car. if one wants a sub 135 mph car - na is the way. if one wants much more than that, start with a ZL1...or build the short block in an ss right out of the gate.

imho it takes a lot of attention to detail for a stock internal blower car to work properly. i pulled on a few with an honest 125 mph bolt on ss 1LE. i put 10-12k miles a year on that car (no winter & not a dd). it never missed a beat, 100% reliable. i had 0 issues outside of 2 bad injectors @ 20k miles.

I feel like the riskiest mod I want is a heads cam package mainly for the chop sound and top end power.

King is talking about me and I drive my car 4 to 5 days a week. I'd rather bolt on a 650 to 700 rwhp blower with TooHighPsi port injection then build a NA car that has to be torn down to add the cam, port the heads, dod delete, High Ram or Msd, Headers, xpipe, then you have to run an aftermarket converter. You tell me thats cheaper and safer as a daily driver? My car still gets over 20 mpg on the hwy on E65 and drives like a stock car in traffic or anywhere you want to go. Yes my car runs 9.80s@142.96 with a drag pack, it will probably run 9.90s on my drag radial street setup. I promise you that E85 NA isn't going to MPH like a blower car. My 16ss with a Maggie ran 9.41@147 5 years ago. It takes a lot more than most think to build an NA car that will run with a blower car, most of those are making 550 at the wheels and they are stripping all the weight out to run even close to a blower car and getting those cars down to 3200 lbs, my car weighs 3800 with drag pack and 3900 with drag radail street setup. I'll take my setup all day long smooth sailing. Price an NA build from Pray Perfomance, you'll be surprised what it cost.

Boost is not everything in building a blower car, I'm running less boost and more timing on E65 with my 2300 Maggie, ToohighPsi Porting injection. Just running 11 lbs, I could probably run 12 or 13 fairly safely, but that's pushing the stock piston ring lands. Tuning is what can save a motor from destroying itself with too much boost. Not even going to get into the amount I ran on my 16 SS and it lived a 180 passes and 12500 miles, then it got mad and broke a couple pistons.

No kidding, I wore out several 55 gallon drums of VP Ms109 on the red car and I sure wish I'd had port injection back then, that would have been awesome after I built the Manley forged short block. Much cheaper for fuel also, 14.00 for Ms109 per gallon and 2.00 to 3.00 for E85

I want to add that I've run some really fast NA cars at WWTRaceway and they were running 10.00s to 10.05 and trapping 132 to 133 to my almost 143, I can tell you there is a big difference in trap speeds on an NA car compared to a blower car with similar ETs. So until you driven a fast boosted car that's hauling ass on the big end and that NA car is running out of steam at a 1000 ft there is no comparison. Just sayin

No, it's totally worth it. I had only a PD blower with a JMS and a tune for quite a while, putting down 560 rwhp at 7 psi on stock internals. It felt great, almost like having a 9 liter NA engine, very drivable and enjoyable.

So E85 is a must to run the amount of boost everyone here is talking about safely?

Last car I had was 7 years ago, LS stuff. I'm just learning more about this LT stuff.
