Made obsolete by the 0w40's? Whats your opinion on Mobil 0w40 Supercar oil?

Erics posts lean towards helping the novice engine builder. You and I may know that most things need some work. "Bolt on performance " is a myth. I didn't see the need to insult the man on a public forum. I can see where your coming from. In my opinion though, what has run off a lot of th...

LMFAO... He just posts stuff time and time again, proving he doesn't have hardly any experience building engines.. Just wow.. and all the nut swingers will rattle his name off to the first person asking about heads without having any personal experience with his stuff. Even Jesel and TD rockers som...

This thing ever hit the dyno?

I didn't want to clog up Kevin's thread on intake manifold so I have a couple of idea's for upgrades. As mentioned on previous pages going to bigger comp roller 266 - 272 @ 0.050 " Looking at the big trickflow intake manifold, I have not done proper measurements but it is 1206 felpro at the fl...

Whats your plan for the dowel pin situation? Drill the head?

How many are you looking for? Tom Id be looking for 16. The S&S lifter limiters 33-5338 measure .115" as you already know. I assumed they were still available, now that ive looked I see everyone is showing out of stock on them. So those take about half the travel out of one of these lifter...

Does anyone know of someone that sells a spacer to limit travel in a GM LS, SBC OE hydraulic roller lifter? I have used the ones S&S sells for Harleys in these lifters before, but they arent as thick as what im wanting. Looking to take most of the .200ish travel out. Please don't recommend an af...

I've seen this argument many times over the years. In the OP's case, assuming lobe selection was good enough to go either route. I'd go with more lobe and less ratio, at that lift rule.....especially if its flat tappet which im assuming is the case.

You install the back one from the front, then the front one from the back....using the cone. If we're on the same page here, or talking about the same tool?

Lost one E85 station near me in the last year and a half or so. Missouri. Still got one real close and a few in the general area. Hopefully it stays that way.

That someone has a low understanding of dynamics?

Not necessarily.

Not meaning much coming from Sim Master Z.

It would just depend on if one cam was perfectly spec'd. There is no such thing in my opinion. Ideal opening and closing points change continually through the rpm range. There is no magic that a sim or internet expert can give you. Buy a couple cheap cams, a cheap hex adjust, rent some dyno time, r...

The perspective is incomplete as I'll also have to know the advertised values for the 235/235 cam. That may prove difficult. My objective is to compare overlap values and then ask you if you think that could be a cause with effect. And this is not to dismiss the change a different IVC and ICL might...
