It wouldn't be very hard to spend twice 2 grand for a good top haft.I suggest you look for heads for a 350 to have intake runners no more than 185cc's.

HP ratings isn't what makes a street driven vehicle whatever it is.Those HP ratings generally have a peak in RPM's that are not generally used in daily driving.As you said torque is the focus you need to look at.The lower the torque curve,the better off you are.

Yes,I read where you said you didn't want to stroke it.But for the shortest path to your goal and the budget you stated,that is within the range of possibility.Just by the nature of C.I.'s,torque in bigger C.I. engines happens in normally driven RPM ranges.Well the torque curve begins at a lower RPM in bigger C.I. engines.And hopefully without getting into a debate of longer connecting rods VS shorter ones,the longest connecting rod you can fit into it helps aid in building a lower torque curve because of the longer the pistons dwell at TDC.So a very mile 383 would easily get you to your goal.Oh yeah,the thing is for the people closest to you when they want to know why your 383 is so much stronger than theirs,well you can just leave out the fact of the longer rods.It will make you look like a pro engine builder.

One last thing-for a 383,your looking to intake runners at 195cc.You want to maintain the volume of the intake charge at lower RPM ranges.But try to keep in mind you can always do a update with a set of heads at any point.The stroke and at cost of 2 grand is another matter.That is a building block that needs to be done first.
