351w stroker in 65coupe

if you're only shooting for 400 hp, i'd stick witht he stock stroke 351w. A simple performer rpm package can be added (just get the performer rpm heads, intake, 750 cfm carb, and cam, pair with an exhaust/igntion and you're there, without even looking at gains you can get from slightly different manifolds or cams). You only really need a 393/408 if you're planning on going for over 500 (usually well over).

With the Performer RPM package i mentioned above you'll be making at least 400 at the fly (edelbrocks website has a dyno graph of it hitting 406), and peak power will be at 6200-6300 rpms, which isn't too aggressive. And if those 200 or so rpms do matter, you can bring the power band down with minor exhaust and cam tweaks, even just timing it differently.

As for heads, I believe that Performer RPMs and Trick Flow are the best bang for the buck. A Victor would be a bad choice for an engine that is intended for arond 6k and below use. An Air Gap won't fit under the stock hood of a 65/66 with a 351w. A Stealth or standard Performer RPM intake would work fine. You do not need forged components unless running very high compression, nitrous, or forced induction, none of which are required to meet your goals. If you are going to use nitrous a lot, forged pistons might be a good idea, but still not absolutely necessary.

And the 3 speed is useless as far as performance goes, to my knowledge. A C4 would be better, but a Toploader 4 speed might be easier and even better. Up to you, whether you want to bang gears or cruise.

A 393 is cheap if you build the kit yourself. 3.85" stroke crank, stock rods and 5.0L pistons. Keep in mind 351w are a snug fit on the 65-66 cars but is doable with only a header swap, but depending on motor mounts hood clearance can be an issue

(Please forgive my ignorance, but. . . )Exactly how much are we looking at for a stroker project? Assuming you already have a stock 351W, what kind of money are we looking at for a 408 stroker, assuming you stick with the stock heads, intake, etc.??? would this put you even close to 400 fwhp??? just curious.

Sorry don't mean to piggy back but would the afr 185's on a windsor be bad for under 6k rpms too. I want to get a set of those but I am hoping to push 400-420fwhp on a daily driver that will usually be kept under 6k.

Those 185's should work fine on a 351 and if it was a 393 or 408 they would prob be good too, but I myself would prob do the 205's on the larger build. Personally I dont think I'd ever build a 351, its really not much more money to build a 393.
