Really! I got some junk we want to throw together for the 7de7 I’d be happy with 300hp
You will be tagged for info when we start with it...It will be a handgrenade engine. Old used parts... no money! Lol!

Probably not. Those engines were special. We ran 13 sets of 441 cylinder heads to get to that point. There was some black magic too.
Haha! I bet!
Still going to see what I can scrounge up. I think it will be a fun project for my kid to learn something on.
Buick 455s aren't heavy. By most sources barely more than a small block. And pretty man they are good looking motors
@Bent77 if you go the LS route I have seen a couple advertised for fairly cheap that need a rebuild. Only one complete though.
Keep you eyes out for stuff you might be surprised.
And that’s not out of the question. I’m not in a hurry, so the benefits of patience may reward me.
Still like the lower end torque numbers of peak at 3000
What strikes me as interesting about that chart is I rarely rev my engines over 3000 for any significant period of time. MAYBE 4000 if I'm really pushing over a pass or something. All that power up there at the top would be totally wasted on me.
It’s true. Hence my focus of generating peak tq near cruise RPM
Totally true. But when you rev your engine is when you need power. Even barn doors like our trucks do not need their full torque under cruise conditions.
I look at things much different than guys coming from an almost all V8 background. I drove a samurai and have tons of friends with Toyotas 22r stuff. I'm perfectly willing to rev the crap out of something.
And a moot point, since we are talking a full roller small block but vs alot of small blocks is the rev potential.
I'm sure any full roller Mark builds will be snappy but every tuned LS I've driven the willingness to rev is amazing. Not to say a small block can't be snappy.

The roller cam really makes a huge difference. The torque curve is really flat. Wish I could find the graph it’s actually pretty awesome.
I’ve used this engine in other applications. Snap is an understatement.
Oh yeah it’s 10:1 too
Interesting I didn’t know that about the 455 i never looked at the weights!
And coming from small turbo stuff and two strokes I also use the full rpm range of my motors. More so prob because they tend to last longer by not lugging them.
The ls is actually kinda crazy on the rev side of things. That donut video I posted was actually hard to keep it off the limiter, I was pedaling the heck out of it because I don’t like being on the limiter.. ironically the stock limiter setting rolls the throttle back instead of cutting spark or fuel. So it sounds funny, and Offroad with no traction the thing is easy to blow through the rpm in 1-2-3 and 4th if you are moving.. sand, hardpack.. rock.. whatever.. it’ll spin them. I find it easy to modulate that for whatever reason where a carb sometimes has a sweet spot.. the ls is easy to keep wherever you want it.
I thought about going roller with the 454 until I added up the costs. I'm sure it's a lot more reasonable with a 350.
I wouldn't do the "LS" just because everyone is telling you that you should. Don't be a lemming.....

Well I need it to match my application.
The engine I have now works very well. Enough reserve to go if it needs, decent power. It’s just getting tired. It’s replacement should do everything this does, just better and fresh.
Having a hard time justifying another used engine to replace a used engine at the same cost of a new engine. Getting a used LS is a crap shoot. Don’t know if someone’s grandma had it or 6 form setters racing home after a concrete pour every day

I have a 383 roller motor with tpi and it makes rediculous torque off idle.
I vote LS it's modern, more power better drivability. Every auto parts store has parts on the shelf.
My 05 Tahoe with 206k just blew head gaskets. All it needed was a resurface for good measure and new valve seals... Original lifters still looked great and every cylinder had cross hatch still in it.
To me this is carb vs fuel injection. I respect the Gen 1 block it paved the way just like a carburetor did.

not with the flexibility of aftermarket EFI systems available now.
But can you go to any auto parts store and by replacement sensors? What are the aftermarket systems based off of?
That’s a legitimate question. Anyone know about the origin of the sensors or how the limp mode works on the Sniper and FITech?
