torque specification chart

[Cleve]

Any suggestion for a good torque specification chart for my 302 ford engine I am installing in my MK4 roadster.
Thanks so much
Cleve

Google search gives a bunch. This is one: https://www.torkspec.com/torkspecme.aspx?KI=11-5.0L-302ci-V8-WINDSOR

[i.e.427]

There are bolt torque specs listed by size in the Appendix D section of your assembly manual.

Resurrecting this thread to try and get some more specific information. Recently completed first start and I've gone through a few heat cycles now. Blueprint wants the torque checked on the manifold, headers, throttle body, valve covers, etc. I'm hesitant to use the generic info in the back of the FFR manual since it doesn't address wet or dry, bolt material, what material it's screwed into, etc. The torkspec info seems much better but I'm still hesitant because it doesn't address things like head material, wet vs dry, etc.

I've spent a bunch much time searching the web and even more time trying to find info on BP's site for their 347, with no success. Seems odd that BP wants these checks done but provides no info to do it. And soon I'm going to need to recheck all of the front accessory drive. Don't have those specs either.

Plus, for a lot of these bolts I don't know the material, the size, the thread, etc.

Any advice on how to find the information for this specific build? Am I over-thinking this?

Planning to reach out to BP to see if they can help. Not feeling optimistic about that though.

Thanks,

Pat

STOP over thinking it. Everything other than head bolts and rod & main bearings are non-critical torque loads, so common rating are fine. You are NO where near maximum loads on those fasteners, in fact I don't use a torque wrench on those, just good-n-tight

If you bought the engine from Blueprint and they say to check the torque on their fasteners, call them and get the torque values.

This is why I don't care for BP, they're just too big. Deal with Forte, Prestige, or Smeding and you get more personal service and quick answers. I'll step down now.

For heads and intake, go to the manufacturer's website. They are sometimes different from stock.

I'll go one farther than that for the final answer---if you are using specialty fasteners such as ARP use their recommendation.

You're right on both points Mike. Blueprint would have the data on what they torqued all of those fasteners to. For past questions, I've had my best luck going back to the sales guy that sold me the engine. He's the FFR rep. In fact he's at every build school. That's where I first met him. He got back to me this morning and said he'd get the info from tech support.

I chose BP mostly because they are FFR's partner and figured for a newbie, that would be the way to go. If I could do it over I wouldn't make that choice again. Oh well, next build.

The heads and intake are BP products and they did the complete engine assembly. They responded this morning indicating they will track down the info for me.

That's true Jeff, but since BP did the entire assembly I don't have any info on the fasteners they used. And, as ARP pointed out to me recently when I spoke with them about my header bolts, they reminded me that when going into a soft material like aluminum, it's that material that sets the spec, not theirs.

Good advice. I'm definitely guilty of over-thinking stuff, especially when new to me. I don't have the experience that many here do, and could just see myself twisting off one of those bolts. If BP doesn't send the info I'll be going with the good-n-tight method.

Just keep in mind when doing good-n-tight, small bolts get small good-n-tight. :)

I always tried to use the 1/4 turn before it breaks spec, especially on the small fasteners.

A tried & true method

Here's the info direct from Blueprint tech support specific to my 347, but I assume they would apply to others in that series as well.

Intake manifold: 18 ft lbs

Throttle body: 10 ft lbs

Headers: 24 ft lbs (20 with Remflex)

Water pump: 15 ft lbs

Valve covers: 10 ft lbs

Cylinder heads: 70 ft lbs

Water neck/thermostat housing: 18 ft lbs

Harmonic balancer: 90 ft lbs

Timing cover: 15 ft lbs

Spark plugs: 25 ft lbs

Back when I was building my roadster and was rebuilding my 302 EFI, I used all the torque specs from an OEM Ford manual, other than a few such as the BBK headers, and the aftermarket alternator bracket. Sixteen years and no issues.
But...in your case, presumably with a engine warranty from BP, I think you are very wise to go with their recommendations.
