how much horsepower?

Mad Dart said
I would probably do it with a 360ci motor. Run about 12-15 lbs of boost with the ability to dial it up to 20-25lbs of boost max. I have all the parts to do one accept the pistons and the turbo set up. Maybe do a single turbo?? IDK, trying to learn as much as I can. I may change my plans on the 67 Dart.

What about all these guys running BOOST with stock internals and they live? Do you absolutely need a HUGE $$$ Engine to make it work correctly with boost? I am beginning to think that is a MYTH!!

The DynoJet is a Chassis Dyno right?? Those numbers are to the pavement?
Damn that is knarly for a little truck!

To the pavement. That's over 800 flywheel.

I would go with an h beam, a forged crank and a good dish piston. Yeah some live, but not at this level. No way...you usually can get about 450 rear wheel with a paxton and a good tune before **** happens with the factory guts. I know "this guy" who blew his stock motor at that level once upon a time...tee hee.:-D

Anyway....

These are his pistons...and I think you can figure out what gasket goes on there.

And yep, that's a MAG block!!!
It's filled, but I doubt a block fill does a whole hell of a lot. It does something I know, but how much, who really knows?

But in a motor like this, the pistons are very important.
Weird arent they? Those are custom diamonds I believe with a special barrier coating on them.

Factory pistons WILL NOT live at this level.
They will die well before that.

Anyway, not to get too far off topic, let this be testimony to what the block can live through. Will it work for everyone with every day mom/pop machining and budget parts? NO. But done right, there it is.:cheers:

So in the context of your n/a stroked smallblock, you have nothing to fear about the block as long as you dont get too stupid.
