Re: New motor options: F___ing' Big Block or small block?

That's not a problem, they will just put a sleeve in it! I got 2 sleeved bores in my big block I got in my Chevelle, from nitrous blowing pistons apart!

Yep, sleeve one hole and rebuild.

It's always amazing to me to see pics like that and wonder how MORE stuff isn't screwed up. I mean, the way that piston looks you would think that engine would have just grenaded completely killing everyone around with 454 shrapnel.

NO ****!! We couldn't believe it either...I think I was lucky. Found small pieces everywhere, but this was the only damage. Hope to take the block to machine shop soon.

Update:

-motor is at machine shop where they are doing there work. Looks like I was lucky, as posted above it was just 1 cylinder. Decided to go with a 496 stroker kit.

-dropped off the stock heads and intake to get some work down on them as well. The builder said he would recommend what cam to go with. Sticking with the cast heads..overall they are in good shape and I will spend minimal $ on these.

-All along I have talked about building this for low end, up too 5,000 rmp. That being said I hope to put it back together very soon, just a few more parts to pick out

If you don't mind could you do a parts list with cost? I'm weighing doing this to my $200 tow rig and a actual cost would be awesome! Mine is a '98 model so is full roller and best heads stock from what I have read?

496 stroker big block....Thats gonna be a beast of an engine!

ARP head bolts are hitting header flanges on both sides...

Clearance header flange or use different head bolts??

Clearance the flange if you got enough material left afterwards!

Any updates on this? I'm considering building a 496 myself.

Motor is in. Makes very good power. Very pleased with how it turned out.
-high range is much more usable
-low end torque feels much stronger
-haven't beat on it yet, but all indications are it's exactly what I wanted out of big block: instant torque and lots of it, reliability and simplicity
