Separate names with a comma.
The power valve doesn’t control how much fuel is added when it opens. The number on it indicates WHEN it opens relative to intake manifold vacuum....
For the record, the power valve does not affect idle. It can’t. There are videos to prove this out.Several folks on here have tested it and...
If that’s on pump gas it’s rich and the timing is slow. And the plug looks cold, but slow timing takes heat out of the plug.
Here is a picture of two Chrysler lifters. One is a mid 1990’s lifter and the other is whatever Jim at Racer Brown sells. You can clearly see two...
Take a picture of the pushrod seat in the lifter. That what dictates what ball goes on the end of the pushrod.
1.084-1.087
Put the lifters in a lathe and run a dial indicator across the face to make sure it has .0015-.0022 taper/radius across it.If they have that,...
You just can’t shim the stands up. They have to go up and away from the valve.B3racingengines.comLook him up and call him. He will correct it...
And of course RRR tree’d me. Again. I’m just too slow...
If a Holley tech actually told you 9 pounds of fuel pressure is ok, that only reinforces exactly what I’ve been saying about those jack off’s for...
You can use them. The tang doesn’t do anything but line the bearing up side to side. The crush between the bearing shell half’s keeps them from...
I like that distributor
What brand and heat range plug is that? It looks pretty cold to start with.
If the thrust is gone from the converter side that’s on you. That means you didn’t get the converter all the way into the transmission and it...
.007 isn’t much for that piston. I think MT had those pistons made by Jahns. Or however they spelled it. I’d use them. I’d just make damn sure the...
I only replied (again) because the dude is just dead wrong. I don’t give 2 runny shits what anyone does with their timing, but claiming that MVA...
So an engine that needs say 35 or so at idle is correctly built? That’s nonsense. Something is wrong with it if ANY engine wants that much timing...
He will never agree because he has a fundamental misunderstanding of what a vacuum advance is really for. If you junk engine build requires that...
It depends. If you build the engine with enough compression and the correct cam timing you most likely will never need manifold vacuum. Too little...
Another legendary member. Sorry for your loss.
His fault in all this is not covering ALL these things before he agreed to do the work. You shouldn’t be buying a torque plate unless you can make...
I agree 100%. The piston should have the clearance built into it. If it comes out the box at nominal size I’d send them back.I also agree that...
Did you actually read what I posted? I didn’t excuse the shop for not using the plate. I explained that the OP isnt a machinist and he has no...
Yes, math is crazy Yang diabolical.
Yes, that would be .001 per side if you have .002 clearance on diameter.If you think about it, the piston grows half of what ever it grows on...
Your machinist was 100% correct on the pistons. The bore size is nominal. The piston has to be smaller than the nominal bore size. The...
RRR takes no prisoners for sure.
Because the spark plug angle going into the head is much more perpendicular to the piston stop, I’ve found that the stop needs to go much farther...
Let’s hope the heads ship by May. At this point, I add at least 50% time to whatever the seller is claiming for a shipping date.
I’m thinking about the oil hole in the thrust. It makes sense. In fact, it makes sense even for a converter car if you are going to lean on it. At...
