Separate names with a comma.
It is all about the exhaust scavenging effect that starts at mid RPM. If you are always operating up in the mid to high RPM's, then the DCR...
The wife's real statement was: "You put that JUNK on my clean floor?!?"
Now you've put something in my mind that I am going to have to think about... LOL. There has to be a good explanation.
OK on the white mark. Yes that would force you advance the timing 35 degrees to get it to line up at the same point as the new damper. Looks like...
Which timing mark were you using? The white or the green?Just started reading this.... the balancer slipping would be the right suggestion and...
IIRC , I don't think it is exactly 90 degrees off. You need to find #1 TDC with a piston stop and then remark 0, or apply the timing tape. The...
I did this on an odd ball head in the US (Opel CIH type head) and it used old 9 mm valve stems and so I could not find an arbor to fit. So I made...
At some point, just getting the tool and arbor and turning the spring seat a bit deeper may be easier. You don't need to do a lot here. And maybe...
That is a lot to put up with RF! That is poor manufacturing work.Yeah, the problems seem to be getting gradually worse. The hydraulics I have...
That is higher than I usually allow. I find them more commonly to be in the 5000 ohm range, + or -, for the main wires, when new.I see this link...
Just looking for data points here. The question is what is the maximum acceptable lash closure rate rate (or lobe velocity) for when a solid...
Lets' make sure we are saying the same thing.... you cannot go to coil bind. You have to maintain at least .060" to coil bind. Which is why I went...
Thanks very much. That is quite helpful. This was this cam like I was thinking would be a bit better; it looks like it is from the Howards...
Yes on the 9:1 BUT realize that the factory published compression numbers were exaggerated. if you work the actual dimensional data, it works out...
And before you buy anything else..... let's look at that clearance to coil bind as you numbers don't look right: 1.65" installed - 1.100" coil...
So it will really be about 8.5! Better than the older smog engines.OP, a couple of question for you:What cam is in there now? What is the...
There's money to be made here... just follow the trail of pocketbook-damaged afficionados and help them pick up the pieces LOL
Since your heads are ported, I'd think you would benefit from a more area-under-the-curve type of cam. I was not thinking MP, but one of the...
The need for ZDDP varies with pressure lifter-to-lobe; this has been discussed in the research articles. Low pressure stock springs and mild ramp...
Just a word of caution: There have been a few cases reported here (including pix) of the dipstick getting caught by the crank and a piece broken...
It refers to DCR which is dynamic compression ratio. It is a computation of what you might think of as the 'effective' compression ratio of an...
As above, pressures sound good hot with 10W30.Synthetic is not going to particularly clean out the engine. High detergent oils will. So a...
OK, so mixed use, mostly over-the-road driving. The cam size makes more sense now. It is not a big change, so not sure how much it is going to...
Yes... the cam question dropped to the bottom of my list when the OP showed the smooth operation in his latest video. But valvetrain-related is...
So OP are you talking about a Comp XE274H (flat tappet hydraulic)?What is the main goal here? Best strip times? Or daily driver?
If there is one hole, they go down. And don't think they 'squirt' as much as they just 'ooze' with the stock oiling system. The pressure up in the...
FWIW.. stock 340 pistons won't balance with a 318 crank; you have to add weight. But I doubt that the OP is going with old heavy 340 pistons....
I had a Ford 302 act just like that. It would start to run rough and miss erratically when hot. If I stopped at a store for 5 minutes and started...
Well, this is how I used to buy Rislone LOL Vintage Shaler Rislone Engine Treatment Full 1 Qt Motor Oil Can FULL NOS | eBayBut I think you want...
Making sense now..... And I see the rear seal surface in pix 25 looks boogered up....So are you going with all new bottom end parts there OP?...
