Re: Intake manifold CSA

:D Nice looking intake you've fashioned there! CSA really depends on how high you intend to rev it. I would expect a 393 cu. in. engine with those head and cam specs to rev to around 6,500 RPMs. That would require (in theory) a round port runner cross section of 48.75mm diameter. 41mm round port cro...

Re: flywheel to balancer weight proportion- inline 6

:D Sounds like a great way to do it, Mike! I have 3 separate plenums under 3 carbs to heat, but it should be pretty much as you and Tony describe X 3.

Thanks,

Harry

Re: Server times out

:-D Will do! I can do E-mail and look for car parts. Guess that's all I really need computers for when you get right down to it.

Best regards,

Re: This morning...

Its amazing, Kevin. Saw your reference to Jethro (played by Max Baer, Jr.). I remember his Dad as being a boxer back in the 1930s. Jack Dempsey worked with him to shorten (pull) his punches because Baer had such a hard right that he killed a couple guys in the ring. So I googled the name Max Baer. M...

Re: Server times out

Well, I gave it a try. Got off into unfamiliar territory pretty quick. Decided to leave these sorts of things to those who better understand them and stay with what I've got for the meanwhile. Wife is younger and knows more about computers than do I. She has been talking about going to a VPN and fin...

Re: This morning...

I hear ya! Have a friend in Australia. We have kept in touch since the early 1960s. I remember in the '70s there was a push here in America to 'go metric'. No ambiguity...... Folks here either loved the idea or hated it (engineers, machinists and mathematicians loved it but most everybody else saw n...

Re: flywheel to balancer weight proportion- inline 6

Harry...I found that water heating the intake only required 5/16 steel lines..I even had a valve on one line to restrict the flow...In the hotter weather where you are you might be able to turn off the water after the engine is fully warmed up...Have a cable control in the cab...I was using an alum...

Re: Server times out

Thanks for the info. Computers are a mystery to me, but I'll see if I can do it. Bear in mind that I'm an old fart. Still have my rotary dial phone and made a decision some years back never to get involved with 'social media' and never to own a 'smart phone'. Do OK turning wrenches and fiddling with...

The GMC's were solid lifter, .990 diameter....The cam was a one off tight lash reground from a the NOS cam done the by the late Lazer Cams..212 degrees at .050 lift and ,440 valve lift....The engine had 9.5 static compression, but not the best with .060 quench that gave me some detonation issues wi...

Re: flywheel to balancer weight proportion- inline 6

The more I hear about the fluid filled type dampners, the less I want to use one on this particular engine. Why? Please post links or explain. I am not arguing, just want to learn. As I've said before, I'm running a modified SBC streetdampr on my inline six. If that is a bad choice I want to know w...

Re: Server times out

Thanks for the heads up! I'll give it a try. One question..... If I do identify the source of the problem...... My very limited understanding of computers tells me that I cannot pick and choose my servers. If that is indeed the case, what will I do to keep the Speed-Talk server from timing out? This...

Re: flywheel to balancer weight proportion- inline 6

My apologies. Have been experiencing problems with the server timing out here. Was in the middle of editing my priour post to add a note to Juho and got bounced off the forum here 15 hours ago. Just now got back on...... Juho, my crankshaft weighs about 13 lb. more than the one in your Volvo. Flywhe...

Re: flywheel to balancer weight proportion- inline 6

Thanks, Kevin, Chris, Juho and chevyfreak! Much to consider. I believe that I will either use the OEM 8" malleable iron dampner I have here or pick up an ATI dampner. After reading more about the Fluidamper and changes that occur to the silicone fluid over time due to internal friction and heat, I b...

Re: Compare 89 leaded gas to 91 10 percent ethanol

I would suggest dynoing the engine running whatever fuel you will run it on in your car. And if the dyno room is set up (not all are) so you can run whatever exhaust you will run in your car as well, so much the better.

Good luck with your build,

Harry
