Torq Link comment....they should have built one for the 351W. Why this poor engine is left in the dark as far as available intake manifolds is beyond me!
But I found the one I was looking for thank goodness for the PME!

When did Howards end up with Harold's grinds if they did. And how did they? I really miss UDHarld is why I ask.

Another point, somebody mentioned the old "Torque-Link" intake, how can it be modified to compare/perform like a good dual plane like the old 300-36 and RPM? I ask because I like it's longer runners IF it can be made to operate over a much broader rpm range.

Howard's bought ALL the designs, programs and everything else that "Custom Camshaft Company" had, when Harold started to get sick.
Thanks Walter,

I didn't know Howards bought everything.


Anybody want to comment about the old Torque-Link intake?

pdq67
From the results I have seen ... if you don't have a Small Block Chevy of 355 cubic inches with 11/1 compression ratio and need the extra torque between 4,000 and 5,000 RPM ... don't use it.
The power is worse everywhere else.

In regards to the torklink manifold. There was a well known competitor in the early years of engine masters(2,500 - 6,500 rpm) that did extensive mods/testing with that manifold. IIRC, they told the magazine(whatever that's worth to you) doing the article on the build(hotrod?) that the design made more torque than any other manifold tested very early on in the powerband. But was eventually tossed aside when they realized it penalized them far too heavily in the upper ranges to hurt the total points too much.

Incidentally, that's the concensus I had heard and read about prior to seeing that article. Good for towtrucks.. bad for mid-range and top-end horsepower.

Kinda like the SP/2P Edelbrock form the 70's during the gas crunch, I don,t miss those days at all!

Well it LOOKED like a great manifold too bad it didn't work out. I read where it was designed for short track racing to get off the corners better.

It does look like a bitchin' intake. Runners too big?

I am building a 427 SB Ford using the very competitively priced DSS short block. The purpose of this build is to see just what can be had from 427 inches in terms of cost. The build is also a test motor for TFS twisted wedge 205 cc port 11R heads.

I would like any comments from anyone who has built a 427 using a stock block as a basis for such or anyone who has built a DSS 427.

Additionally any feed back from the heads would be nice.

Also I have not settled on the cam type here hyd. or solid nor the intake manifold single of two plane. Either way I am targeting a minimum of 600 lbs-ft from this build and it must be street drive-able on 87 octane fuel.

Your thoughts here gentleman!

DV
This would be a fun project. Let me know if I can help. We can have GS grind the camshaft. As far as finish and cores, Glen Steyers stuff is top notch.

Believe me Bill I will have the final say but that does not mean it won't be swayed by what my potential readers want to see. As for cams I am leaning heavily toward old Jonesey but the book's not closed on that yet.

What about Cam Motion. Or Racer Brown? Hell lid love to see some of either of them tested.

I ran a Racer Brown cam many years ago. It was a used flat tappet grind the was supposedly speced by Racer himself (he passed away many years ago now).

It was a street/strip deal and ran like a champ in my 350 SBC.

DV,
I will call you. We lost our server over the weekend so I'm a bit blind right now. Backup server is operational but we are behind from yesterday.

Godd stuff - I will be in most all the afternoon flow testing so make an allowance for me to hear the phone and get to it!!

OK guys here we go!
Chris Straub and I are in the throws of concocting a cam spec for the TFS 'R' headed DSS 427 build I am doing for my SB Ford book.
should have some details on this by this evening.

Watch this space!!

Well at this point Chris and I have gone back and forth on a cam for this 427 and guess what - we have differences of opinions here.

Chris wants to see that super big top end number and be at one with whatever low speed torque this build may make. And who can blame him with 427 cubes on hand the low speed torque is unlikely to be much other than good.

But from my point of view I am trying to see the best low speed torque consistent with a little over 600 hp. After all this is a street build and the 2000 to 4000 rpm range will be used much more. Chris's response to this is 'but yes my spec will be faster on the strip' - well no argument from me on that point except I am only on the strip 0.1% of the time at the most.

So here's the deal - this engine is for the readers of my book - that's guys like you lot out there. which way should we go favor the street or the strip. the only difference here will be that Chris's cam has about 5 degrees more exhaust duration for that extra top end haul. And no this is a choice of one or the other. tis cam has to be the right one first time as there is EFI testing to do on this engine and belive it or not dyno time cost 500 a day and I am not excatly made of dough!!
