What is the reasoning why a Gen 2 Hemi can not be a bracket motor. NSS is a bracket racing class, dial you number and try to match it. Lots of time you can be running someone a second slower in the 9s.

What are your options on a 5 inch stroke. At one time Callies did not have a crank available, do they now and what are spec on this crank. If you sell the crank you have would it be worth the money in the long run going with the bigger stroke. Time and money is your decision. The old KB Company might not even be in business anymore. The New KB blocks have many changes from the old KB Blocks for the better. You might want to email or phone FHO or Barton or others that are Venders for the new KB, the owner of Marsh Performance is a member here. They all would know what your block is.

Yes they are!!!!! Best sounding bracket motor you will ever hear....

wouldnt want a 5' stroke. what you give up in durability, makes it not worth it to me....... I have 4.5 stroke in my street car and it made 1000 on pump gas, we shift it at 8k and its happy. have an old steel norris rocker on it which have been fine, but if i had my choice i would have the RBRE rocker gear!

Ya there’s no chance of me changing cranks now and my plan was T&D rockers but I’m going to look at Jessel as well

Kevin

My Barton T&D rocker set up weighs about 35 pounds , no $hit

The 5" crank brings with it an expensive cam, not everybody carries a core so it's a custom cam only and belt drive or now possibly a gear drive too. But the extra displacement gets expensive.

Fixed.

Nope you’re right not cheap at all

Kevin

I agree the RBRE rocker gear is so nice and has plenty of benefits. Not cheap but what is now a days.

No rocker assembly is cheap for Stage 5 Millenniums

Kevin

Why not stageV rockers?

No difference in price for rockers, so may as well go with T&D

Kevin

Just curious How efficient are tunnel rams at lower rpms?
Say under 7500rpm

Kevin

My Weiand on my 605 made 765ftlbs@3500rpm. I d never even consider going to a single 4bbl after getting TR dialed in. It's got fantastic street manners and explosive acceleration.

I'd love to see a comparison on your motor b/t your current Weiand tunnelram and the Indy tunnelram w/ a plenum spacer on it. Back when I was considering using a tunnelram, all the hemi guys said anything less than the Indy wouldn't be worth it and even the Indy needs a big plenum spacer on a big inch motor.

Chip it would be a fun test. I'm pretty sure I'm leaving some on the table with my setup. I'm pretty sure some spacers to increase the plenum volume would help. The current setup all fits under the hood, barely. I just don't have any room to go up without cutting the hood. I refuse to do that.
A modern tunnelram should easily out power it, but at the same time I can't use all the power I make now. I have to slow it down or get bounced off the track.

I understand your situation! It would be an expensive test unless someone loaned you a manifold to try. I'd just love to see where the old school stuff stacks up. It's a shame there aren't more tests done like this, but I guess there aren't many people racing hemi in the grand scheme of things.
Like when I was trying different single 4500 manifolds...I had to buy one of each to see how they compared. Sure, you can guess which one will run the best, but until you try em firsthand you don't know.

Just think Chip now that you're spraying you need to go back and start all over and check to see if anything changed with what manifold it likes with spray. LOL

Funny you say that b/c I'm fixing to put the biggest one back on the car. It hurt the lowend grunt real bad on motor, but that won't be a problem w/ the nitrous.
