You sure play "God" a lot in this forum. What qualifies you to decide what the rest of us should and shouldnt see as far as posts go?How can you know someone else wouldnt find some relevance in them?
If you decide to leave a thread in Advanced forum, you ought not to prune the replies.
Kind of miffs me that I take the time read all the way thru this, and then find out someone has edited others posts.

Just my opinion. Now I guess I`ll find out if the mods here can take constructive input or not......................

Amazing.... you read a 4 month old thread, and out of the blue decide that I pruned out things you might have thought were relevant. As I recall the thread was pruned for one of the following reasons:

1 - There were duplicate threads, both with valid responses, the two threads were merged, and duplicate posts were eliminated.

or...

2 - Two people got in a very personal pissing contest that had nothing to do with Advanced Tech, including the posting of some ethnic slurs. These inappropriate posts were eliminated.

What is your specific complaint... What relevant material do you feel would have been deleted by the above actions?

By the way, please e-mail me, since board rules (not mine) discourage direct posting of complaints about the moderators decisions.....

If you are unhappy with the job I do, send a complaint to Jason Debler or Chris Frezza and let them know your concerns... I'm sure they will give you a fair hearing.

I personally don't consider myself playing "God", but you are entitled to your opinions.

Have a nice day.... .

What qualifies us? The position as a Moderator given to use by the Admins.
Want some info from the admins, here you go-

What Are Moderators?
Moderators oversee specific forums. They generally have the ability to edit and delete posts, move threads, and perform other manipulations.
Oh and from the rules form that you agreed to when you signed up-
We reserve the right to close or delete any message for any or no reason whatsoever.

with the advice i've gotten from him, and the things i've learned about my car because of him, Injuneer may as well be God. I probably have more respect for him than anyone else on this board.

Sorry..........maybe I spoke too soon.

And I do know that a moderators job is seldom appreciated.

4 month old or not, still a good thread, and didnt want to miss something that might have been relevant.

And I dont question any of the mods automotive expertise at all. Have read the forum enough to know better .....

I do appreciate being able to voice my opinion, wrong or right, without repercussions.

With that said, I think it would be appropriate to put an end to this discussion.

I think that given the same cam the 383 will make less power than a 355 up to a point...


A 383 needs a bigger cam because it has more space to fill and thus needs more time for the air to come in..

the higher the rpm the more velocity and the longer it needs to keep the valves open because there is a lot more velocity in the incoming charge due to the piston speed and thus creating more vaccuum inside the cylinder that has to be filled and the way is via 1) more duration 2) more overlap...

rod length also determines what type of cam and a cam for a 383 will not be ideal for a 355 and viceversa...

I dont know where you get the word efficient...

The S2000 consumes more gas than an ls1...

I think in this case "efficient" applies to the hp per ci ratio.


Just to keep the discussion going, Fred, would you mind commenting on why you went with your setup (3.75" crank) vs a larger (or smaller) one?
My next project will be either a 383 or 396 and I'm looking for as many opinions (hopefully based on knowledge/experience) as possible. Things like rod length, piston ring lands/wrist pin location, etc. are all concerns for a given setup.

Yes... always wondered how ARE makes so great MPH on just 396 MOTOR... around 120+mph with just a 396.. I know that also here the climate is a LOT more humid and Hotter... so that has an impact.. but anyways...

Stock bottom guys can run 120+, even on the "crappy" LT1.

Its a bit "late" but BBB if your going to race your going to want to swap that pan anyway.

Easy..... nitrous.

I just thought the 3.75" stroke and 5.85" rods would give me pistons that could survive a 300-shot. Giving up .125 off the top of the pistons didn't seem worth the extra 12.7 cubic inches.

Well consider this the 4th gen fbody is no light weight, so the more cubes the more torque to move the mass, the car will be quicker with less gear. Also the killer of engines is rpm more than piston side loading and unless you are going to switch to a solid roller cam you are going to be sort of rpm limited with a heavy hyd roller aren't you.

I know of streetable hydralic motors turning 7500, so not TOO limited in revs

these days, even low rev apps(<7k) are running solids due to there better streetablity.

Agreed.
In a stroker especially, a solid in the 240-246 range @.050 is plenty livable. Manual trannied cars make it that much more "streetable".
And yeah, guys are turning 7500 with hydraulics but that's where the hydraulic to solid swap needs to be made in my opinion. Lose a lot of valvetrain stability with hydraulics in that range.
