260?

In all honesty you will be right at or about 260 hp just as they state the numbers to be.

Maybe a little bit more on the top end with your headers and free flowing muffles and intake. If I was to put a number on it I would put it at about 275 to 290hp range MAX and that is pushing it.

The 260hp GM crate is rated at 350 ft.lb. of torque.

All around GR8 truck engines though IMO.

RJ22...

EDIT: these are a GR8 base for add-on mods also, the limiting factors are the cam and heads. You could bump up commpression while doing these mods in the futuer real easy to make some real nice HP

yea, that engine is advertised to have 260 hp and 350 ft/lbs of torque "with four barrel carb and headers" so thats prolly about where you're at.
