stock bottom 6.0L with arp bolts, L92's and GMPP single plane, 242 246 cam, ultra low elbow and 90mm, mine made power to 7900... stock rockers. 3 seasons old, and is now being street driven more this year. fresh set of valve springs this past winter.

so with a forged bottom, with proper machine work and assembly, i wouldn't see any problem spinning a 4" stroke crank 8000.

NOW, on my 418" 6.0L block 4.100" crank, we are still spinning it to 8000 with a eagle crank and rods wiseco pistons. its a solid roller, and I got T&D shaft mount rockers on it, All Pro Hurricane heads with custom port work and 240's runner. Super Victor and 4500 TB.

I'd say my 418 is the fine line between the oil system keeping up and having the good valvetrain. a lot of work was done to the block to feed the top end with the proper amount of oil. All work was done at Bischoff Racing Engines... Top notch work.

 

We have seen the ultra billet Callies turn 10500 easy on Jud's car at 4 inches or so.

The 4.250 was a Sonny Bryant CCW crank as well like the Callies Billet Ultra.

Joe's 402 with a 4.000 stroke CCW SCAT Billet also turned over 10K and holds together.

The center counter weights help a ton in keeping the crank straight at that higher rpm.

The Billet Ultra CCW Callies is about as awesome a crank as I have seen though!

Very nice work and thanks for those cranks Callies!

 

Drag racing short duration you can turn even 8500 with the wet sump and a good pan and oil pump but any endurance or higher rpm we go to drysump if at all possible.

8500 plus rpm or really big power and the ccw cranks are much better as well.

 

It will be a blast to drive every day! I work in the country, so I don't have traffic or stop lights to worry about. I also have a very mile long straight on the way to work(the test track, lol). Hopefully I can go mid 10's on motor with this combo and spray it to 10.0(I'm only doing a 5 point cage).

 

I only spin my 416 LS3 to 6800. rev limiter set at 7k. AFR 225's with 8019 springs, Yella Terra rollers, 248/254 hydraulic roller on a 112+2 LSA.
Ported FAST 90/90 SCR is a bit over 11.8 to 1. Car is a beast and pulls like a freight train from 3k to redline. Power numbers are in my sig. AFR is a very safe 12.3 and total timing at 22* due to **** 91 octane gas available here.

I have my rev limiter set at 7200 rpm. Cam is pretty small 244/246 615 lift on a 114 lsa for the cubes. Callies rotating assembly.

 

i think the real question should be: what type of hydraulic lifters are all you using to get into the 7000 range? I have the Comp "high energy" lifters, comp pushrods, and Patriot extreme dual springs with Titanium retainers, and lightweight valves, and im just worried that those lifters wont be enough.

has anyone tried the Comp "short travel" race hydraulic lifters?

 

Tie bar lifters will help.

 

Yes, solid.
Titanium intake valve, stainless exhaust (can't remember on the exhaust side), Manley nextek springs, T&D rockers.
My valvetrain will handle more "rpms" than my bottom end and oiling system I believe.

 

7400 in a 402, ported Gm single plane w/ 2" tapered spacer, 256-262 @.050, 0.690 lift on a 106lsa, solid roller.

 

I run the PBM High Rev hyd lifters. Same thing as the morel's.

 

I didn't realize we were talking a serious build. The one I mentioned was just PRC dual springs, stainless 2.02 valves, and factory oiling system and lifters. Definitely not pushing the limits of the Callies crank or rods.

 

I'm really surprised so many rev their engines so high. I have a 427 built with a LS7 block and try to keep the revs under 6,800. I have morel lifters. On the dyno I peaked around 6,200 though.

 

Yes no hydraulic roller deal is stressing the crank and rods whatsoever!

 

whats your definition of a good quality pump and oil pan? please try to be as specific as possible.

It all depends on the application and vehicle but the truck pan is great and so is the Moroso.

 

the moroso is good. i am running the moroso f-body package. pan, pick up, windage tray and pump. i will be pushing my little 408 to the limit on rpm's. i say around 8500. .263/.271 custom solid roller, t&d shaft rockers. my limiting factor is my crank.

 

So here is where I am at:

4.081 bore x 4" stroke
AFR 225 heads
245/260 106/109 .646/.629 hyd
CTSV lifters
Factory Rockers with upgraded Trunions
Super Victor
NX 2 stage plate
4150 to dominator adapter
Edelbrock 2,000cfm dominator TB
Traditional carb hat with 4" filter and K&N Top filter
1 3/4 stepped to 1 7/8 Hooker Headers with High Velocity Merge Collectors
Dual Electric Cut outs
Truck pan / Pick up


I had originally geared the truck based on a 30" drag radial and the 347ci motor that was in it and a 7,400 max rpm. I was trapping at 118mph NA / 128mph on a 100 hit, with plans to spray a 300 hit. I had a 4L80E so I figured I could lock the verter up top if I had to, leaving enough room to go 144mph (which I didn't think I would get to, but I knew I had room to grow).

I recently built the 418 mentioned above. Here is the dyno thread with the 4L80E: https://ls1tech.com/forums/dynamomet...na-no-n20.html

Shortly after the new motor I swapped out the 80E for a powerglide. I haven't had it to a track yet, but I know it is quite a bit quicker with this new 418/pg combo. I did some 1/8 mile racing on an abondoned airstrip a couple weekes ago (really cool event) and from what I can tell my 1/8 mph is up quite a bit. There are no timers/clock so I am relying on info from my Gtech RR (Which has always been dead on for the 60' and .1 / 1mph fast at the 1/4). The old combo went 96ish mph in the 1/8 on the Gtech where the new combo is showing 104-105mph. I had some traction issues there (2.0x 60's) so the mph might be a little high do to tire spin. But even at say 5mph over the old combo, my guess is I'll be trapping 124-125 based on what I know my truck picks up on the back half. At this event I also ran side by side with a Plymouth that traps 128mph, and beat a Comet that traps 124mph, we left side by side and I pulled him by 2cars in the 1/8. Both of these cars should have batter aero than my farm truck and that would definately show on the backhalf for sure.

If I am at 124mph na, I think I might be close to running out of gear on motor alone.

4.56 + 30" tire + 124mph = roughly 6,800-7,100 depending on verter slip

Since the current cam combo peaks at 6,750, I either have to re-gear it, put a taller tire on it, or get more RPM out of it. I have a set of solid rollers, adjusable rockers, push rods sitting on the shelf. So in a sense, I'm more than halfway to a solid roller set up. I'm going to guess I would need roughly 8,000rpm out of it to be able to spray what I want on it. I'm thinking with 124mph NA, 300-400 hit should get me high 130's to low 140's if I can make it all work.

So now that I know what rpm others are doing, I know that changing the cam set up to get more RPM out of it is a viable option. Just a personal question now of, do I want to go that route or change the gear / tire combo around. I'll be taking it to the track before I do anything, but something to keep me up at night with

 

7000 in a truck with a 415, and 9 pounds of boost on top.

 

I have used these lifters and i think they do good work if; # one you deburr them, and # 2 you polish them, i did and they are worth at list a few more horse power, that way, it just converts them to a notch above, however you better have a set of adjustable rockers, ather ways, it will be hard to make work with the .010 max crosh alowance. But one thing is for sure they are the sheatters they were mean to be, and you can rev them to kingdom come.
