Thanks, I am an AGM fan, but I need something smaller than a Group 75 (which is pretty small) and it has to have a port for a vent hose.
I guess I should just start measuring from the Oreilly's racks, might be an easy way to see if there is an existing battery that is more commonplace
You never win conversations/arguments like that, so it's best to let them just think that they are right.
There's so much false stuff floating around the internet and for some reason, it just gets forwarded and passed down for years, by a bunch of guys who think they know what they're talking about.
Ehhhh just ignore it. He used a bunch of my calibration info years ago and grossly misunderstood it.
He ended up using 76 jets in 2x4 550cfm carbs and his conclusion was that the FE just doesn’t make any power.
Couldn’t be more ignorant.
Even from the Factory… FE’s came that way. A little shorter on the exhaust valve than the intake valve. I’m sure the reason why, was because the exhaust valve is hotter than the intake side. Little more spring pressure.
I was under the impression that it was done because the exhaust valve and seat faces were expected to erode faster than that of the intake side and hence provide a bit more time before servicing might be required.
Scott.
Long story short I had some larger valves put into a set of 6090G heads awhile back. I'm finally ready to get them installed but noticed what appeared to be differing valve stem heights upon closer inspection. A straight edge and feeler gauge says all of the exhaust valve stems are .007 to .008 lower than the intake valve stems. Spring closed height is within the specs I gave the machinist. In retrospect, I probably should have given one specific install height to avoid any confusion. I made the assumption the machinist would make them all the same height but within the range I gave. Live and learn I guess.
This isn't a race engine. Maybe classified as street/strip but in reality mostly street. Thoughts?
I have a distributor pulled from a '74 (?) pickup and rebuilt for use in my mild 390. I told the shop what the application was, and on delivery I think he said it had 15 degrees centrifugal and 12 degrees vacuum advance (I may have those turned around...)
Anyway, he provided no testing documentation and I'm concerned the advance curve may be inappropriate for my car and engine combo. '65 Thunderbird, .040 over 390 at around 9.5 static comp, C4-G heads, streetmaster, Lykins custom cam, 735 Holley. I've tried to decipher the distributor ID: C5TF 12127, 4KD, but am only ASSUMING it's a truck dizzy. Were the advance curves customized from Ford for each application? What springs/weights would be the closest match to my needs?
TIA, Jeff
Run it, .0055 sounds big by today's standards, and of course it may have a little piston slap, but I bet you won't even notice it.
