1,500 HP ?!?!!?!

Dang!

Where did you see 1,500 HP? I didn't see that inbthe article

Next to last paragraph:

"At the tippy-top of the food chain, and limited to just 25 units, is the 70/SS powered by a twin-turbo 7.4-liter big block LS6 claimed to put down 1,500 hp."

Ah hah. Twin turbo, now that makes sense.

Even though I am not a fan of it, I wouldn't mind giving something like this or even one of the factory Cobra Jets or Demons, just to see how they drive at speed.
I've said it before most people have no idea what it's like to have that kind of HP on tap under their foot. Far too many have more money than common sense or talent

 

[thunderchicken]

I should probably clarify that I don't for a second think my talent is superior to many others. Just emphasizing to go that fast is nothing at all like driving any old school muscle car or even most sport cars.

In my experience launching a car with that much power is a full body experience that's not so easy to describe

Point taken. Way back in the day when I graduated from the typical "slap on a 4 barrel, aluminum intake and headers" 302 engine to a fully thought out, 475 chp 351w the additional 275 hp was eye opening. I can still remember the silly grin it gave me the first time I let it scream. One can only imagine and probably no where near accurately, the feeling of 1500 hp the first time!

I remember when I was a bit more youthful and went through the as you put it "slap on a 4barrel, aluminum intake and headers" phase.
Driving a car with 450-500hp is/was an eye opening experience.
Like I said, I would like to drive one of the factory Cobra Jets or Demon or even one of those special edition Chevelle's in the article a handful of posts back. Just for the experience and for my own comparisons. I know they have a smaller tire and no doubt they aren't geared to get out of the hole as hard. So, they would have to be a different experience.

For lack of better description, it's almost startling the first time you launch a car and your vision goes blurry for a second or so before coming back into focus.

Pulled the lifters and cam out of the Mountaineer 302 tonight.

And by "pulled" I mean struggled. The lifters are hydraulic roller and have this valley in between two machined shoulders. Well apparently there was a nice ridge inside of every single bore. I had to use a pair of pliers to get them all out.

Of course I forgot to snap a picture.

My question to you all - is this common? Should I run a nylon or brass brush in each bore to clean them up and call it good, or should I be concerned?

Replacing the cam and lifters yes?
Post a picture showing the ridge. It may require bushings

I wasn't planning on replacing the lifters. I was told that, with hydraulic lifters, it's not a requirement to change them so long as the lifters are in good shape. They appear to still be in good shape.

I'll get a pic on my lunch break.

Rollers, that can be correct. flat no. new lifters with the cam.

For my money I'm putting new lifters on a new cam, roller or not. I've pulled cams and lifters and reused them as a unit when identified to the bore otherwise lifters are disposable or at least stored for reuse on the cam they came off of.

 

[jeffsqartan]

Pictures of the bore and a couple of the lifters. The ridges or deposit or whatever is coincides with the space in the middle of the lifters.

 

[Jaybird1980]

I'm in the replace them group. If they were fairly low miles I would probably reuse, but these have what 180k on them? Although it does look cleaner in there than I expected.

Nylon or brass brush chuck it up in a drill, use some kerosene or something to help cut the carbon. Are you tearing it down all the way?

Right now the only thing left in there is the pistons rods and crank.

I don't plan on removing those. Hitting those bores with a brush tonight and starting to reassemble.

Did you pull the bearing caps and see what the bearings look like.

It didn't knock when I drove it so I'm calling it good
No but really, I'm not planning on pulling anything like that. The Sloppy Mechanics way is that if you don't look at the cam bearings, then they're fine. Funny thing, I looked at the cam bearings and they looked gucci. With a lack of glitter in the oil pan, I'm gonna just assume that the bearings are all good.
The other problem - I don't have bearings and I don't want to wait for bearings to come in. I'm so close to getting this done.
Also, I found this yesterday and I'm not sure how I feel about it.


Spending more money on an engine that's likely to blow up when I add boost, just sounds silly to me. Save my money for a 351 build or a good rebuild of my current forged piston engine (depending on what I find is wrong with it when I pull it).

Churchmouse calls you the mad scientist... until now I mostly agreed. But the logic you are sharing here makes me think you are demented.

Putting boost to something that's likely to hang rods out of the block just doesn't make sense. Too much chance getting in your own oil and destroying a car.
If you are just reusing everything why did you even pull the heads, cam and lifters?

Maybe I'm the odd ball here, but some y'alls logic with your builds just seems lost to me.

I checked the lifters and they're not acting how the internet says they should. I hate to do it, because now I'm waiting even longer, but I'm buying lifters. It doesn't seem like anyone local has them, but I'm about to start making calls.

I pulled it all because it needed new gaskets. Also, on this design, it has some basket thing for the lifters and you can't remove that without removing the heads. And I'm changing the cam.

I mean, hopefully it doesn't blow. I'm gonna run it NA for a few weeks just to make sure it's not going to explode NA. During that time, I'll pull my engine apart and see what it needs to be rebuilt. I might rebuild it and put it back in.

Good luck with it. Seriously I hope thing turn out how you'd like.
Just seems like a whole lot of work swapping tired old engines that at least need to be freshened up

I wouldn't be feeling good, I know that
