with 440-1s besides jesel or t&d what is the next best rocker out there?I`m on a budget,so every penny counts.


thanks mike

Mike, what size cam , what spring pressure, what size springs, these things can mean the difference between being able to use the Harland Sharps and needing the Jesel, T&D's. John

Harland Sharp seems to be popular with some builders but they aren't inexpensive either.I decided to go with an old set of Isky irons and have them bushed and corrected at RAS.

wow, I just checked out the price of Harland Sharps complete set up $1090. Jesel are 1955 plus the 150 to mill and set up head. John

the current cam is 278/285@ 50 lift 700/680 its a roller.I`d like to go bigger if it will help the cars performance.

here is my current set up

400 to 511
4.25 stroke
6.535 rod
over 13.5-1
fully ported RPMs
rocker-Harlands
victor intake matched to heads

I`m hoping by changing the heads and intake (maybe the cam)
I`ll pick up a bit more Hp


thanks mike

you have HS'S now? are thinking of changing ratios?

the -1s take a offset rocker,don`t they?

hows the saying go: "pay a little now or alot later"

the intake rocker on the -1s are the only ones offset,right?
if thats the case,could I buy just the offset rockers and use the ones i have for the exhaust side?

mike

if he used boost he could have the HP with a pulley change or wastegate twist.
sorry for the interuption.

what rollar cam lift and duration spring presure open and closed


this will determine what rocker to use


my 715/280 rollar took out two H/S rockers


soon I will have cnc 345s and will use jesel setup for them

The Harland Sharps will work just fine, I sell tons of them and have used them for over 20 years. When you get over the approximate 800-850 open pressure, its time for Jesel od T-D. Some of the H/S will go 1000#, but not the Mopars.

You could just re-use your exhaust rockers and buy intakes only.

I am going to run my annual H/S rocker deal starting next week. I can save you on a complete set or price just the intakes, but I think you'll see its worth your while to get a whole set as opposed to getting individual rockers.

I will shoot you a PM.

I'll advertise my sale at the beginning of the week.

Thanks

Todd

ARI...those should have been fine. I have been running them for years on .780 cams and zero problems.


Do you still have the broken ones? I'd like to look at them if you dont mind..on my nickel.

I have to look for them ,I migth have thrown them out ,not sure thougth


one rocker split in two and the other one was striped at the threads

I ended up putting a solid cam back for now


also the rockers had miles/runs on them


do they fagtige (sp) over a period of time ?

Yes, they can definately fatigue. It makes more sense now that you mention they have "miles" on them. They are excellent pieces in my opinion, but like anything, yes they can break over time but I would have to assume they have had a more than useful life. I just dont see them break without an explanation of oil starvation, too much spring, binding conditions, plugged oil holes, over-revved etc.



I just took a set off a car last year that I know had 17 years on them. It did finally break one and it was time to call it quits.Put a new set on and hope the customer can get another 17 years!

If you haven't already purchased the 440-1 heads then maybe consider going with the EZ heads instead. The EZ heads are capable of 800 hp when fully ported and they'll accept standard rocker arms. That means you can reuse your existing HS rocker arms and save some cash.

Thats a good thought as well. EZ's and SRs also use the standard rocker set up you have.

The -1s will obviously make more power if that is in the plans later on.
