Re: Hot honing or not?

Seems this discussion just might give some credence to Total Seal’s “Total Conform Ring”? When first released, my gut reaction was these were a bandaid for shoddy workmanship. Now I might have a different impression?

Re: roller cams in AMC 401 engines

Ken is right. To ad to that, and only if installing the bushed lifter bores is out of your budget, I have found that the AMC lifter bores are pretty much spot on with the angles and spacing so you could go cheap and not rent or buy the BJ Lifter-Tru fixture.
FYI - T&D makes a shaft rocker system.

Re: Worst-case Header Sealing Scenario? What to do?

Nice bead of “Right Stuff”, let it sit about 5 minutes and slap them on. Will never leak. About $15 for a small tube.

Re: Factory 396/427 chevy cylinder heads

It should also be mentioned that NHRA has allowed BBC several “superseded” part numbers for the 396/427 cylinder heads; including offerings from Edelbrock. There has been much development on not only the cylinder heads over the last few decades, but also in the short-block and drivetrain. Long gone ...

Re: Factory 396/427 chevy cylinder heads

Vortecpro do you race stock eliminator if so I was wondering how a bbc 396/427 chevy camaro can run in the high 9’s at 3400# plus with a head that is suppose to be stock with such low flow number compared to a 351 cleveland.The heads would have to be ported out to max and covered up to run over 135...

Re: ? steel shim gasket for sbc 400 ?

I have made my own steam holes on composite head gaskets. Harbor Freight punch set and a block of wood under the gasket with one swift blow by a 5# hammer gets it done!

Re: Hot honing or not?

i don't agree on some of the points in OP as it seems like it is saying for a given engine the torque plate can be either steel or alloy. it must be the same modulus as the head material otherwise the local deformations are different and simply using a thinner plate if using steel is not equivalent...

Re: Lighten an I - beam rod

I like that video. On you SBC rod, the BE is .940” wide. If you went to a NASCAR wrist pin guided rod, I believe they then narrow the BE of the rod to somewhere around .720” wide with the beam centered equal distance from each end of the BE. Then the bearing width is also reduced. You can buy new pi...

Re: can Oil be TOO slippery ?

Back around 1977 and in HS, bought a ’69 Mach1 with 351W 4-bbl (one year only option at 290 HP), 4-speed. Used very little oil. Then somebody came out with a graphic impregnated oil and it was all over the advertising. So I bought it. Engine immediately idled better, ran better, faster. I was ecstat...

Re: I think we should take a good look at the 445 Thunderjet

Hopefully, this lights a fire under GM; so that GM produces a competitive pushrod "big block" engine of world-class design and execution. Preferably with greater bore spacing than the FE-like Ford. The Ford 7.3 gas engine seems...restricted...in that area; but I can't find bore/stroke info . 4.220”...

Re: Does fuel movement in bowls during acceleration impact AFR?

If the float level can effect the rich / lean conditions due to the weight of the fuel on the jets, then I would surmise different amount of “slosh” can have some effects also. I am a firm believer in isolating vibrations to the carb as I have seen for myself that vibration isolations on my AMX Stoc...

Re: .120 wall pushrods

I made a VERY expensive mistake when ordering my Manton Series (5) 3/8” - 7/16” single taper .168” wall thickness 7.900” pushrods. Even with the taper, the 3/8” end ever so lightly contacts the solid lifter link stand. Guess what happens? Even rotating the engine over slowly (what I thought was goin...

One question; do any of your programs use slick roll out measurements instead of slick diameter?
