Good choice on the intake.

But being poor is no excuse. 

While I have seen Thumper do some very nice work.  They are still a stock head on a way more cubes than they were designed for - prof. ported or not.

Save your money and get some TFS Fast as Cast 190 heads.

As far as a cam?

Thanks 4 the help, I'm really concerned about piston to valve clearance and I've heard that the 351 can't take a 2.02 intake valve without dish pistons is that true? I understand that I will have to save but I can only afford to do this once so I need a well put together combo. Thanks

1 - Always check piston to valve clearance
2 - The TFS twisted wedge 190 FAC is perfect for the 351W
3 - Any factory head.....even the GT-40 is way too small for a 351W.

I love it when GREAT information is being shared!!!

And this you need to concentrate on.......

Anyone, and I do mean ANYONE, who tells you Bull$h!t like this, you need to run the other way.

I imagine it is the head guy....... Roll Eyes

I have been told a plethora of times that you cannot run an afr185 head on a stock shortblock too.....they are too big and they have 2.02 valves.......I have plenty of folks doing it.

Sir, the difference is most people just regurgitate what they have "heard" and twist the words around so they sound intelligent.  The fact is, only a few have actually done it.  And that is what you'll find here.

Not to hi-jack this thread, but I've see you guys say that the 170 t/w aren't big enough for the 351w? Why?
For me this is the end goal, just wondering if I need to reevaluate.

http://sbftech.com/index.php/topic,22103.0.html

And to the o/p, this thread deserves a look IMO.

Where did you read such a blanket statement?  I would not agree with that... it depends on the builders/buyers goal... but I would never buy a set for 351 or more cubes as they limit the room for growth...

Just recently, I read where Jay said that he wouldn't use a set of 170's on a 347.  I may have misread  I'm sorry

I see the correlation on running out of room.
My thoughts have been that I would go with the 351w, but if I were to ever change engines I would get a 347 shortblock from Woody and reuse the 170's. The 8.2 deck would definitely be a better fit in my car. Just thinking out loud, I suppose.

A lot of guys have made a lot of steam over the years with a TW170 and a 347.  They work, and they work well... but technology has again risen and we now have a TW190 head with all standard port placement and a similar cost.  

If you aready have the 170's use em...

You also need to look at the difference between a 351 9.5 deck windsor and a 347 8.2 deck windsor.

I don't have the heads yet... waiting for a while... project on back-burner right now.

Yeah, I know the difference between them. Intake, headers, and such.

Thats what i did a couple of years ago. I had a 357, Diamond pistons, Comp Cam 588/622, 246/259 dur @ .50. HP 750, Vic Jr. The car had approx. 11.1 compression and power ran through a TKO. 3370 lbs w/ driver. This combo was good for mid 11's at 119mpg. A good driver would have probably seen .30-.40's. I love the old TF's but i've traded this car for a SN w/ 351 and will be buying better heads for it soon.
