are their any cons to a .250 raised cam block such as, lifter/push rod angle or anything I'm not aware of?

Lifter angle usually changes from 45 to 48 degree or vice versa, pushrods are a bit shorter, need a belt drive for raised cam

Belt drive or KB Gear drive I believe are the only option for cam timing and they are proud of both.

I think the Jesel for raised cam is $300 more.

Maybe not, I just want to think things thru before I pull the trigger on a KB.
either a 4.625 which I gather is no problem with Oliver rods, or maybe a 4.750, which sounds hit or miss with steel rods.

If you're talking about your predator deal, it's a raised cam right? Tony had to do some very light touch up with the 55mm cam we used. Personally, I wouldn't go 4.75 again unless it was a predator or like flow head, there's no need.

Mine is a raised cam deal, with a Jesel and 60MM bumpstick. Sorry I did not make that clear. Honestly if I do another predator I think we may go less stroke max bore the block can take and as much RPM as we can to make power.

Non raised cam, oliver 2.200"rods,4.750"stroke 55mm cam with .540" lobe lift (1.028" at the valve )only a very small amount of materal needed to be removed from rods 1-3-5-7 to achive .060" cam to rod clearnce.....

4.75 stroke in a standard block is very doable with 2.2 pins. Dave

Ditto on the only con, at least when I built mine, being lack of a timing chain option so need to go with a belt drive or timing gears. I'd go with the timing belt in any case. Much less resonating in the valve train (= durability) and it's nice to be able to phase the cam without removing it! Mine picked up 20+hp by retarding the cam a couple degrees on the dyno. Based on the low exhaust temps - we expect it would have picked up more by turning it back more if we had confidence in the piston to valve clearance :} My understanding is you can go with a much longer stroke crank too with the raised cam block. Good luck with your project!

that cam height and diameter work great on shortdecks with short strokes to!

IF I do another one that is exactly what we will do. Much smaller cube much high RPM deal. I wanted to try one of the "big" Mopar motors but cannot say I am sold yet.

Then again MAYBE I need to look into a procharger

You can really make some power with the short deck stuff.(and I'm using those junk indy heads) those long stroke tall deck engines are heavy and waste power. nothing better than short pushrods, a great line of site to the port and light weight. I'll take RPM power any day over low rpm.

You won't ever be right again if you go blower, especially with the heads you have!

Oh I know I am low deck guy for sure. I have Indy heads too, just don't tell anyone. TO be honest this was not my idea originally to go big. I have been coerced into building a big mill, and have been skeptical from day one. My B1 is a low deck and does quite well and the 99 was a really short deck. Just wish I could have a bigger bore but being a Mopar it is what it is. I aint afraid of no RPM

Looks like the boy and I will be ordering up a couple of KB blocks this year...

Guess I have a power waster with my raised deck over squared combo...shift at 7800rpm and my engine builder says to go higher as were still making over 1000hp N/A at 8200rpm

I will see soon enough I suppose. We have had to make a lot of changes to my stuff to make everyone happy. It should hit the dyno in the next couple months and will surely let everyone know what it makes.

Kind of a oddball piece as it fits a raised block with no spacers...Koffels had Brodix cast it and it had no logos of anyone's...It's the prototype that was floating around a few years ago at the Nats when I stumbled on to it...Never understood why it wasn't put into production as it works really well !!!

Self split it as was to large to port correctly...Self's are the designer of the 2 piece(bolt together) manifold that Brodix sells for SBC !!

If the extra coin for the belt drive is not a problem...........there is NO downside to the raised cam block, regardless of stroke. Raised cam, with a 60mm blank would be my choice

The Jesel belt drive will set you back $1500 and the cam maybe another $1000.

The cam core for the 48 degree is also more expensive.

A 60MM core is expensive period!!! Then when you start wanting swapped firing orders etc they can get dang hard to come by for a Mopar. Let me know where I can get one for $1000 and I'm all over that. And NO I would go to LSM again

Even with the standard cam journals expect to pay around $400 for the 48* cam.The belt drive is north of $1400.

when it comes to max performance there can't be a budget point.
