I couldn't pass up the deal on these from a local. Theyll work much better than what I had, which was nothing. Lol
Not saying your wrong but... cid will at the very least add useable torque, I am attaching a link to an article done where they used a 393w and ran a set of e7 heads on it they flow miserably low numbers as we all know. The 302 only made 210hp in this trim but a 393w made 387hp and 461tq with the same heads. Albeit a much larger cam.
Amen and x2 on the cubes... cubes=increased torque in any scenario, be it by stroke OR bore. There just ain't no getting around it, haha.
P.S. Fascinating article...I'm with you in that the added cam timing helped provide the huge horsepower bump, which is text book. But man that's a torquey bugger...what an unmerciful tire shredder that sucker would be; And for pretty cheap!
I'm pulling the motor in my sig out of my wrecked 95 to put in the 94 cobra. It has 185 ish on the block but the heads were reworked @ 182k for a broken spring on no. 2. I did not at that time have the bottom end done as I wasn't sure if I wanted a 302 still or wanted to stroke it and didn't want the car down too too long. Now that I'm about to pull it I'm kind of wanting to finish the 94 though it has a running stock motor in it wish 270k and runs damn strong. I want to finish that car so I can get started on the other 95 to which I'll do a 351. So yeah many projects to work on and I'm thinking if for some reason I am tired of the 302 setup that I've had for quite some time, I'll later pull it and either do a 306 or stroke it using the same components. It'll likely be a 331 though as for the intake I have I'm sure it'll be better suited for it overall. I think it's actually a little too big for my current setup but the car is already tuned for it.It’s really simple despite Kurt’s claims. Most guys were always shooting for 300/300 benchmark on 302s with a H/C/I combo, and few actually hit it. Several of us have the 170’s on strokers and have evidence of 330-350/350+ numbers at the wheels. You’re telling me 30-50+ horsepower and torque at the wheels is nothing? Plus the better foundation for future upgrades...
yeah kind of what I will do if I do a 331 later; just use the parts I have. Reference to my last post aboveIn defense of Kurt's point, even though consensus seems to be that you will pick up power, a 347 wants a 205+cc head and with such a head, they push up into the 400s to the tire fairly routinely, these days. Disclaimer: Not all 205cc heads will necessarily get the job done, but most will.
Anyways, it sounds like the OP's got a lead on a smokin' deal, and I'd encourage him to go for it.
For what you're looking to get, you will be more than happy with the TW 170's on a stroker. My 347 with the 170's is by no means a slouch and is reliable as heck. However heck is reliable.I couldn't pass up the deal on these from a local. Theyll work much better than what I had, which was nothing. Lol
I think it's a realistic baseline. It's going in my 66 Mustang Coupe. I'm looking for a fun driver, nothing crazy.For what you're looking to get, you will be more than happy with the TW 170's on a stroker.

If your goal is 350/350, you will get that easily with the proper intake/fuel set up, etc.

I don't have the sheet on me right now but I got 395 ft./pds with my 170's on a 347.Since this is a discussion on heads, I want to know where the torque numbers are between those two heads on say a 347.
I ask this because I could care about hp numbers. I'm on the street and my feelings have always been torque numbers down low in the rpm range are king on the street. Am I wrong thinking this way?
Found it!
The first run was right after break in. The second one was about 1,500 miles later and some tinkering with settings and plugs.
I don't think anyone is wrong in thinking a particular way, because it's a hobby and it's different strokes for different folks. However, you can get more torque at the wheel through gearing. You can never get more power through gearing.Since this is a discussion on heads, I want to know where the torque numbers are between those two heads on say a 347.

Sure, it's not a secret recipe.That's just over my power goals, but very impressive.
Can you elaborate on your combo?

what would be your suggestion for him in a nutshell? Maybe I'll be doing the same thing come one day, similiar situation. Right now I'll put the motor from my sig with 190 k in the 94 cobra. I'll change the exhaust and few other things while I'm messing with it and see how I like the car overall. If I think I need more out of it I'll need to decide rather I just want to do a 306 or 331. I will be using the same components with likely changing the cam if I do a 331. I'll also be more than likely when i finish the swap doing a 351 for the other car so that's why with the 94 cobra just throwing in the engine from the wrecked car makes sense.It's more a matter of dynamics. The engine power is a factor of airflow. That is to say it will only make as much power as the heads will flow. The 347 just peaks those heads out at a lower RPM. There was a good comparison from Muscle Mustangs years ago with E7 heads, I can't find it right now. I think the strokers eek out more power with the same heads, because they are always compared to a factory bottom end, or factory rebuilds. So you end up with a stroker engine with a higher compression ratio, and more valve relief for more valve lift being compared to a set of TF170cc heads that were taken off of a stock bottom end with 9:1 compression. I'm not saying that going to a stroker engine will yield zero results. I'm saying that I don't think that handful of hp or peak torque going down a few 100 rpms is worth the $1500-$2000. There are so much better places to spend that money.
