high ratio rocker arms

know but I would really like to ? sbf that are converted to shaft ? I,d like to find out as quickly as possible as my rocker guy is fixing to start on a set of 1.6 iron adjustables for me next week. really k=like that top engine design,well thought out. got any pictures of the 2v conversion ? and what top 2 groove pulley is on it ?? that's just the way I,d like to set my engine up including the headers. mind sharing where you got them. I,ve looked at a bunch but yours is exactly what I was looking for.

regards
bob
 
I got the photos off the Classic Inlines website.
I think the top photo is a guy that was on here for a while from down under somewhere.

MustangGeezer and CobraSix used the white box supplier to produce Classic Inlines Roller Tipped 1.6 Rockers, a US made version based on the ST2014 Yella Terra 5/16" rocker hard dimensions, as per thinman56 and others here. Might have been made by Scorpion, judging by the anadised color. Harland Sharpe was orange, BRC (Brooks Racing Components) roller rockers were like Crane or Erson , I think.

These are Street Terra ST2014's

LOOKS to me that a modified sbf rocker will will work. no trunion,no poly lock, jus the adjuster and jam nut on pushrod end. anyways I "should have a prototype setup in a couple weeks. not roller though.
 
and the advantage of the 7.3 to one was a "longer opening time" of each exhaust and intake valve than stock?
With any system (i know human systems better than machine systems) I've learned - you change one thing, gotta change some others. So would you need longer c.rods and push rods to achieve this "longer opening time".
BTW: at the bottom of the last linked page is a "1.72" rocker?…
Ya can't just slap these things on I imagine.

This might be a good place/time for me to repeat my humble request: Anyone know a good high school auto shop manual that could help me with an overview/some automotive theory?
 
I do not believe that you can have a piston to valve problem, the valves are not tipped a lot. If you did a small valve relief would fix that, but I do not think it would ever be necessary.
 
yes my rocker arm guy told me stock was 1.46 off the top of his head so going to a true 1.60 will increase lift by about .045 which isn't bad. having custom aluminum roller rockers will be pricey because volume isn't there to bring cost down. I,ll post more when info comes to me. a prototype set is being made for me. he said give him about a week. rockers and matching pushrods. does anybody need a set of stock non adjustable that only have 57 k on them ?
 
FYI, RAS is out of business but it looks like a bunch of the workers banded up and reformed. Here is a link to their Ford stuff. I've sent them an email asking for cost, achievable ratios, and typical turn around time. They do require a core, so it would appear offhand that they don't just have stock sitting on the shelf. I'll let everyone know what I hear back.

Rocker ratio info in totallity is hard to come by, but call numbers are everywhere. See approx page 806 of this catalogue for Jeep rockers.

Ford rockers abound. The FE vs Small Six rockers are a good first start...remeber, you have space for a FE rocker to fit on a small six shaft if you are able to adjust the lever arm right.


They are FORD - 360 - 390 - 427 - 428cid / 1963-1970 , which are 1.73:1 hydraulic and 1.76:1 mechanical/solid on those, but 1.6:1 when solids are bolted on to a 144-170-200-250 small six. Its based around a 840 thou shaft size



Melling MRS-641 (SHAFT)
Melling MR-859 (ROCKER) Sealed Power # R814 (ROCKER).

It's re-engineered for about 748 thou diameter on the small six.



Melling MRS-652 (SHAFT)

Melling MR-877 (ROCKER). Sealed Power # R810 (ROCKER).

Pretty sure they have the same hard dimensions aside from the diameter.
 
Interesting info. I have never had the extra pocket change to purchase a different rocker set.

Likely with Mike's death and the apparent death of Classic Inlines, I am done with inline 6 Ford power.
 
"….I am done with inline 6 Ford power."
C'mon now.
Still tryin to gather what we can on the sm parts/vendors.
 
As promised...

"Hi Steve, yes we have the F44 I6 Rocker Arms Assy Stock Ratio 1.5 And
also we have a High Ratio 1.6
  The price for the 1.5 is $210.00 + S/H Exchange (Hard Chrome plated OEM
shaft, bronze bushings, re-face contact tip and new screws.)
The price for the H/R is $399.00 + S/H Exchange.

   Thank You."
 
400 dollarydoos is a bit on the steep side so I will have to think it over. I have stock ratio rockers that are fresh NOS so the 1.5 make no sense in my situation. I'm interested in knowing what you guy comes back with for a price point.
 
I spent maybe $100+ on getting my current set of adjustables. If that $400 tab still requires a core, then I'm looking at $500+ all together for a set of 1.6. If that's the case, I might as well just get the Yella Terra set. If I can trade in a set of non-adjustables as a core then I might reconsider....
