Re: Dyno mufflers

Saw where a guy built a box about the size of a small dumpster outside of his building. He lined it with insulation, put a big exit or two on it, and called it 'good'.

Torque to turn over Engine

Hey guys Building a Ford 400M for a friend. Pistons are a weak point for these, but I found some custom Race Tec pistons offered by Clegg Machine for a good price that have a good compression height. They have 1.5mm, 1.5mm, 3.0mm rings. I noticed just how EASY it was to spin the short block over. Us...

Re: Expected et change worth the cost of new AFRs in rail

Hvh has a cnc program for those heads, Speier does iron by hand. If you are not familiar with eithers reputation? Most guys don't like to port iron, as it's harder on tooling and goes a lot slower than grinding through aluminum. Therefore, GOOD work will generally be more expensive. That being said...

Re: Rounding off the sides of the spark plug ground strap

Another 'thread from the dead'... I always liked seeing Big Joe chime in with pure experience. Lots of keyboard scientists out there saying what 'should' happen, and then there was Joe who would simply test things instead of doing a theoretical research paper on them. He can tell you the fine wire p...

Re: Expected et change worth the cost of new AFRs in rail

Good luck trying to find someone to port an IRON head nowadays. Nobody is going to put it on their CNC machine, that's for sure. Would need a completely different program, compared an aluminum head... so you're back in the 'black magic' days of 40 years ago when everything was hand ported. IF you do...

Re: Ford 2.3 marine Valve Seals

Guides are stock. The seals on mine (87-ish I think?) were umbrella. I wanted to use a positive type. You can buy a tool that chocks into a hand drill that will cut the factory guides for an aftermarket, positive seal. That's what I did to my 2.3 Ford. These can be used with about any cylinder head...

Re: Just made a sump. How do I seal the weld leaks?

JB Weld. Seriously... JB Weld. I've used it numerous times to seal gas tank leaks... some repairs have 10+ years on them. Back in the early 90's I drilled and ran a 1/2" aluminum fuel line through the sending unit. Hose clamped it to the original line and JB Welded it to seal where the hole was dril...

Re: Enging Break-In (From Total Seal Piston Rings)

To continue with my comments from cam thread - Any non friction modified engine oil can be used for initial startup, ring seal comes with load and heat cycling as shown on dyno video.

was this from todays webinar that I, without fail managed to miss? Those are about 3 months old. This video is even more recent. Lake Speed Jr. goes to EFI University, and they talk about ring seal and gas ports. They talk about the drilled vertical gas ports as well as lateral ones. They discuss h...

Re: Flat tappet vs roller

These little 289/302 engines LOVE/NEED to spin some rpm to make power, and spinning 6800-ish rpm does NOT hurt them at all. That's past the safe zone for inexpensive, standard issue HR stuff... but prime territory for a SFT. These small displacement engines don't really need all the open area they c...

Why is moly not a good additive for break in? Is that not what all the grey paste that we used for years was?
Read the break-in thread... Total Seal did a couple videos on break-in, and were not a fan of moly when breaking in engines.

Re: Flat tappet vs roller

Good oil with either type of cam is a must for me. For flat tappet cams I use Crower cam saver lifters and Gibbs Driven break in oil. Then use their Hot rod oil or VR racing oil. THIS. Lucas has a very similar oil, their break-in 30wt. Very similar additive package, and can be purchased through pla...

Re: What SBF head is this? 289hipo/302/hi-port iron hybrid

Late 289 hipo heads that have been ported... at least on the exhaust... and had larger valves installed. Standard heads did not have the cast in valve spring seats.

Re: Which intake should I run

RPM with a spacer is guaranteed to run good. Very proven manifold. The Offy POS has a lot of POTENTIAL... but is generally a very ROUGH casting with a plenum roof that is jagged and abrupt. With a LOT of work, they make a good intake IF you know what you are doing. My money is on the RPM with a 1" s...
