My guess is a lot!
Nobody’s going to spend $1500+ For a belt drive on a low hp engine. lol

 

630/650 with the right heads and intake and proper carb and ignition tuning.
RPM 6400
Rick

 

680 hp at 6200- 6400, 630 tq at 4700-4800, WAG 🙂 I wouldnt be surprised if I’m low

 

6000 torque peak 610
7300 hp peak 745
Looks very nice, you should sell those.

 

I figure the worst that can happen if nobody wants it, I get to keep it. I say that 3 times a year, every year. Be a good excuse for pulling the trigger on a 68-69 Chevelle anyway. I've been looking for the right one. Plain Jane with a column lo + hi shift.

 

Are those Hyd roller lifters? If solid I’m sure I’m low on WAG

 

Looks like solids. He said after lash

 

I used a Voodoo 231/239 .600/.600 110 lsa installed 107 icl in my 10.8:1 489 since I wanted air cond. and got 590hp at 5700-5800 and 600tq 4400-45/600 I’m guessing you’ll be Way above that

 

Wow! Nice cam I went on Lunati catalog PDF, looked at it. Excellent

 

To the OP I would say it makes more horsepower and torque than a Toyota Prius and less than a locomotive and the RPM range is 6-7,000.

 

Can you post the measured HP and all the supporting data with the test, looks like you test on a 902 there should be plenty of data.

 

What heads are on the motor could quite read the writing in the video? I am kind of on in the 427 L88 camp of 715/650.

 

That's a good question. They're no names machined, finished in Tennessee using all Manley parts. To take it a step further, these are the first set I've ported and polished since I started using them 2 years ago. I get them from a friend I've drag raced with 25 years works for Nickels in Tennessee. Un-ported we haven't made less than 700hp on any of the 10:1 pump gas BBC's we've dyno'd in the last year. I originally purchased a UDHarold design Lunati solid roller 680 680 255 263 110 LSA for this engine, changed my mind when I read the lsa debate which is an old one, on this board. Alex and I at Lunati came up with this hot street/muscle car/mild bracket racing special grind custom solid roller camshaft, specs after lash 1.75 intake rocker 1.7 exhaust 716 696 256 264 108 lsa. It would be nice to need to rev it somewhere around 7000 rpm's or close, to determine its worth. .

 

I'm going with a peak of 6200 @ 720 and 5400 @ 660. It looks like a really nice piece.

 

Experienced estimate. A friend I've known 30 years who worked for Lunati and bullet says it'll be "snotty" with this camshaft, he liked the Lunati UDHarold design original cam choice. I took those as fighting words (sarcasm), ported and polished the heads, race/performance valve job, JESEL belt drive for adjustment. If it peaks 6500 6600 it'll be pretty decent I think.

 

 

Nice crane there!!

 

Is it possible the the "Ripper Nova" has a thing for alcohol?

 

6600 rpms no matter on my guesstimate RW, I'll stand by my 720; i like the cam. Have fun sir!

 

The plan was no pulls today, just fire if off. Got carried away and made three quick pulls moving cam timing. Made 710, 706, 722 hp.

 

I predict it will make more than my BBC🤣

 

 

I recognize that dyno room 👍👍🙂 my WAG was Very Low, these guys Make Power 👍👍😀

 

J.C.> Excellent. I do the transmission in the third gen Camaro.

 

I got to say Ripper is making some good power with the low buck Speedmaster casting heads. Hes not alone.

 

IMO the Very nice porting work and Very nice parts in heads & intake and of course the rest of the build and attention to the small details goes a long way

 

What rpm?

 

I loosened the lash while it was still hot before we left last night. Higher than anyone one of us imagined! It saw 7400 rpm ten minutes after we fired it. I'll have the final tuned sheets Monday Night. I like this camshaft a lot!

 

Nice built Mr. Ripper /Wrench

I always ask and keep a spreadsheet for "cost per HP"

May I ask what the cost per/HP for this engine is (carb to pan - balancer to flywheel)

Thanks

Alex

 

I have no clue.

Yet

 

It was 5.86 @ 115.7 actually.

 

1.75 intake rocker 1.7 exhaust, 012 lash ramp

 

She had another 15-20 hp in her. Tighter I made the lash, the more power it made.

My guess of
745hp@7300
And 610tq@6000
So close. Did I win the engine for closet guesstimate?😚

 

Is the 252-260 cam card above the cam in the dynoed engine? Best power maybe 2 advanced to straight up?

How tight did you go on the valves?
Very good engine, holds power well , broad power band.

Thank you,Yes Lunati special grind Alex and I at Lunati, came up with. 012 lash ramp called for 020 lash. We made a few pulls with late Saturday night after shop hours with lash at 015 cam timing 2 ahead, two behind and straight up. Made 722 hp 2 ahead.

Loosened lash 020 while it was hot, before we left Saturday Night.

Made 3 pulls this morn 020 lash 2 ahead, 2 behind, straight up cam timing all down on power from 722 hp. Tightened 013 hot lash and it made 725hp. Bolted the shops Bo Laws 1150 Dominator Carb on it, cooled it down, took a degree of ignition timing off it, and it made 749.1. Called it good. It had a little left in it though, for sure.

The shop Bo Laws carb always makes 20-25 hp more than my out of the box 80689 1050 Holley three circuit dyno carb, it has issues. I really need to speak with Joe at BLP about a dyno carb of my own, to start these sessions off with.

 

Killer cam, really like everything about it. Rough idle.
