I don't think my milder build would work with dominator carbs. Thanks for offering.

Might be unobtanium, but... If someone has a Blue Thunder MR Intake they don't need, let me know.

FE Technical Forum / Re: Welding a 427 block
« on: August 03, 2020, 07:01:44 AM »
I've used Midwest Cylinder Repair to weld up an SOHC head that was too far gone to stitch. Probably 12 yrs. They were recommended on the FE forum. Did a great job. They should be able to do a block since the SOHC head is about as big as a block 
It was a proper repair, first they heat the part in an oven to a very high (red) temp and then weld in or melt in cast iron material. I think their main business is diesel and farm equipment cylinder head repair
Some of the guys on this forum or the FE forum have used them. Maybe you can get a more recent review.
With this block after the repair (regardless on how it's fixed) you should expect a full machining regimen

FE Technical Forum / Re: Balancing a Scat Stroker: How much Mallory is typical?
« on: July 10, 2020, 02:10:55 PM »
Scott was right!!! The shop quoted me their typical fee ranging from $250-$350 to balance a rotating assembly and was concerned I was not ready for a $700 once they realized the stroker crank would need lots of mallory. The way it was communicated to me seemed to come in the form of question on whether the rods were too heavy or that maybe they never balanced a stroker. Upon further communication, it was the larger fee
It came home today. I left $700 at the shop ($50 less than anticipated). If I do another stroker FE, I'll try the lighter rods and see if there is a significant difference in the balance fee.

FE Technical Forum / Painting Engine: Assembled or Components Prior to Assembly?
« on: July 10, 2020, 02:03:06 PM »
Is there a consensus on whether the engine should be painted after assembly or at the components stage before assembly?

For Ross: Can you share the part number for the I-Beams. Scat lists weight at 810gm for 26700716 or 2-ICR-6700-7/16

Does anyone have information on Scat's 6.7 I-Beam rod (overall wt, big end, little end) Scat lists overall wt as 810, but not the big & small end
The H-Beams I have are 815gm total, 567 big end, 248 small end. No surprise, the weights are very close to My427Stang's data shared above.

The H-Beams came w/the crank. I see the I-Beams are 810 grams, but it looks like Scat does not list the weights for their H-Beams. So, I don't know what the difference is. Does anyone know the weight of the H-Beam to compare.

I got a call from the shop that's balancing a Scat 2.25 stroker crank and rods I picked up yrs ago. It's for a 482 stroker.
Rods: Scat H-Beam 6.7" (not sure of the weight)
Crank: Scat 2.25 stroker
Pistons. Lightweight from Blair P.
The shop is concerned they will need to use around 3 slugs of mallory and it seems excessive to them. Is it typical to need this much mallory in a scat stroker?
*** I thought this info as I learn it might be helpful in future searches.
***EDITED After Barry's Comments:
***Scat 6.7 H-Beam Connecting Rod: Wt 815gm; Big End: 567gm; Small End: 248gm
***Scat 6.7 I-Beam Connecting Rod: Wt 771gm; Big End: 545gm; Small End: 226gm (Ross's data from below post)
Rods: Scat H-Beam 6.7" (not sure of the weight)

Brent, their is no mention of ball end size, is it universal that one side is 3/8 and one side is 5/16?

FE Technical Forum / Rough Pushrod Length? Felony Heads, OEM Non-Adjustable Rocker Arms.
« on: June 23, 2020, 06:35:18 AM »
Does anyone have pushrod length data from a build using Barry's Felony heads, OEM non-adjustable rockers and stands, and Morel 5325 hydraulic rollers. I need to order an adjustable pushrod from Smith Brothers to use to determine pushrod length (at zero lash) for my build. The Smith Adjuster offered only has .250 range and ideally I can order one that's provides 1/8" adjustment in each direction.
I thought these checker pushrods would have more range, but Smith is the only option I found to get a 3/8 ball on one end and a 5/16 ball on the other. I'm open to alternate suggestions.

Are there any benefits to trying to use and tune the secondary power valve? Seems like it adds complexity, and maybe little benefit for a street engine.

FE Technical Forum / Jet suggestions for Carb Re-build
« on: June 17, 2020, 01:28:03 PM »
As mentioned in a previous post, I plan on using a 3310-1 Holley 780cfm in a 482 stroker rebuild, and would like feedback on starting point for Jets and Power Valves. I know the jets and power valves are more likely than not to change during tuning, but am curious if someone has done a similar build and can suggest a starting point for the jets and power valves to use in the rebuild. The engine is for a '67 Mustang Convertible
Note: The 3310-1 has a power valve in both the primary and secondary metering block.
Mustangtek list a number of 780CFM carbs for various engine combos, Primary jets run, 69,70, or 71; Secondary jets 83. Power valve 65 or 85 (no listings for 3310-1 with two power valves)
Engine Build:
Block: 427 stroked to 482
Compression Ratio: 10:1
Heads: Mildly messaged Felony heads by Blair Patrick
Intake: Blue Thunder MR
CAM: Hyd Roller, Lift .520, Duration 276 total, .224 at .05 (Symmetric)
Exhaust: Will use CJ cast iron, or FPA headers
