[DeTomaso] stroker kit????

Piece one together that fits your needs.  I've seen several of these kits
now that are not put together properly for a 351C.

> 383, 393 or 408 to fit the cleveland engine, 4v heads and high revs (7500
> rpm) (4340 crank).

7500 RPM and increased stroke combine for some pretty serious piston speed.
Perhaps more than a stock 351C (or 351W) block will reliably handle?
If you plan to spend a lot of time over 7000 RPM, most engine builders will
go to neutral balance.  The longer stroke cranks are usually set up for
28.2 oz-in and can require a lot of expensive Mallory metal to balance.
A friend went through this.  His crank required 21 slugs at $75-$100 per
slug.  When he damaged that crank, it was cheaper to go to a custom machined
crank that had the bobweight he needed (no Mallory metal required) though
the crank itself was 3 times as expensive as the previous crank.

You'll want strong and light rods for something like that.  The best bang
for the buck I found were 6" Oliver Superlites ordered through Callies.
More expensive than the typical Eagle or SCAT rods but worth it in your
application.  Have the pistons custom made to your specs.  Assuming you have
quench heads, you'll want a corresponding quench area on the pistons (most
of the kits don't do this) and the upper ring location will be determined by
the canted valve notch.  We went with custom Wiseco pistons for my stroker.

The shorter the stroke, the slower the piston speed and the more RPM you
will be able to turn.

BTW, if anyone is looking for titanium valves, I have a new set of Ford
Motorsport titanium valves for 4V heads that I plan on selling.
