Hey guys, I've been considering putting a 351w based stroker in my 65 coupe and was just wondering what is the best without being overly expensive? I assume the 408 or 393 and will be about the same as far as price goes. Ide like to get around 400 hp if thats not too hard to do. the car currently has a 289 with a 3-speed manual. I want to ditch the manual and add a c-4, is that a smart choice? thanks.
351w stroker in 65coupe
- Thread starter palehorse94
- Start date
Ok I realize maybe that was a generalized question. but what brand of stroker kits or components are you guys running? should It be imparitive to have any particular component forged rather than cast? I really am not interested in turnin alot of rpms, Ide like to keep the peak hp under 6k. also what are the most economical yet good flowing heads? This car will not be a daily driver and will only be a weekend type car and may see some track time a couple nights per summer. I may even decide to put the giggle gas on at some point. what kind of intake? victor jr? air gap? carb?

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.

(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.
I actually have a toploader laying around here.. but its the early 64 type, and I havent been able to find a suitable bellhousing to mate it to a 351. Also wouldnt there be alot more room constraints with a manual? Im not exactly shooting for 400 hp but I wouldnt mind starting there and maybe moving up to a better head later to get more. Ive got about a 2500 dollar budget, does the 393 need any block machining? could I go with a summit cast stroker crank, stock rods, and forged pistons and maybe push it to what 450 horse? could I port the factory heads and still get acceptable performance? what cam would be best? I have absolutely no problem with reving it past 6k but I wouldnt want to have to really dog on it to get it to run. assuming a decent suspension setup with subframes and traction bars what kinda 1/4 times should this thing run?
