Tips, Tricks?

[mytight95]

I got the block for the motor i am starting bored already, still at the machine shop cause they ask me about threaded plugs and a bunch of other options, which of these kinds of things will help prolong longevity of the motor, and or make more power......


I head a high volume oil pump robs power, and doesn't do too much better of an oiling job in a low rpm motor.....


i am just curious about little things like that, so that i can get every oounce of power out of the new motor when it is done. I am sure that some of the "few years my senior" gearheads on here can help out a young buck like myself....lol

come one guys pitch in... ever other question i have posted lately i have being helped with, so now i just about have everything in line to start assembling the short block.... just a few more things to buy...

I never have seen the need for a hv op in a street car.

Maybe one of those stronger oil pump shafts might be a good idea.

Have you thought about a windage tray to free up a bit of high rpm drag?

i already bought the FMS heavy duty drive shaft(oil), and i was trying to find an article on a windage tray to read up on exactly how they work, pretty much a crank scraper or what.......?

i went to books-a-million even, but they had no literature in stock, they said we'll order anything. I said i can order it, i wanted it to read now....lol

feel free to explain this to me grady, i have also heard something about chamferring the crank etc, but what if the crank already has been done this way. I also read about plugging some oil passages to better control oil flow, which to me doesn't make sense...??

help me out guys......

I also heard that knife edging the crank helps a lot, but won't that make it weaker..... something about it slicing through the oil in the pan rather than "impacting" it.....

As Grady said, a HV OP (I like the abbreviation Grady!) isn't going to do anything, and infact, could suck your pan dry at high RPM.

Chamfering the crank isn't necessary. If you use good bearings, and the crank is "in-round," you'll get all the oil it needs.

Don't plug oil passages. They're there for a reason.

The thing that is going to make the biggest difference in power levels is a matched setup. Garbage in always equals garbage out.

well i have a friend that works at the machine shop they are gonna do what he said is the best balancing they know how to do, they said they would balance each, then put pistons on rods, then rebalance (if doesn't check out0does this sound right?

i am working on the combination Joe, the heads and intake are gonna cost more than the shortblock, considering running the heads and intake i have now until i get the AFR, and other stuff........that is in the next month or so when the motor is done...

I hope I did not make you think a tray or scraper would give a huge gain.

I have seen some data to show a really nice gain but it was high rpm RACE CAR stuff.

When we were kids we would put the left bank of pistons in the right side of the motor and vise versa for the rest.

It cut down a little on friction but made a bit more noise.

Got that little trick from an old dirt track racer who was local to me at the time.

Jason, there are all kinds of little tricks like that but most of that stuff is not really what you would wanna do for a street car.

I'm with Joe about trying to match up the parts real good to make a nice combo for the street.

Heck, a good tune will most likely make more power than that other stuff anyway, lol.

i was told it could yield around 5 hp at higher rpm... but if i do three to four of these small things, that would be around 20hp...... just working at it.....lol Planning on using hyper pistons, total seal rings, and try to get the shortblock to as close to perfect specs as possible, crankshaft endplay etc... Degreeing in custom cam with a wheel...

Any opinions on what are the best bearings, i have been told both federal mogul, and Clevite...??? I am also gonna make sure the valvetrain has the correct length pushrods, so it won't be noisy like my setup now, (haven't had time to check and shim it yet).

just using this to Gather ideas..... Have you heard of anyone knife edging a crank, kinda pricey even with the free labor of my bud, they still will charge to use machinery..... bonus is i get to learn a little about the process as i will be ther when it gets done.......
