KRE posted on FB. 468 based on an MR1 block, solid roller, as cast high ports, 631hp, 5900 / 629tqe, 4400, 4.21 x 4.21, pump gas

[GTO Dan]

Following instructions from KRE I made 618 hp at 6200 with KRE “310” d-ports on a stock block 474 with a solid roller spec’d by Jeff K with a port matched Victor , 850 mighty demon and 2” maddog headers on 92 pump gas 12 or 13 years ago...

Is the solid roller streetable?

Regarding the 631 hp 468 combination did KRE divulge the specifications on that solid roller ? Or typical secret squirrel material !

Daily driver? I wouldn’t.

50 mile round trip cruise, just fine. Drove it for pleasure all the time.

Could be tough on valve springs, comp 917, if I recall.

What was the CR?

It would not take any sort of special cam to get 631 HP with High Ports. If you did not at least get close to that with a decent solid roller you did something wrong.

No many high power pump gas hp headed engines out there on stock blocks. But maybe you know of some?

[Dragncar]

631 HP pump gas is not exactly "high power" as far as I am concerned. 600 HP steet'able stock block engines have been around for a long time.
This engine is just a little more powerful. Not sure what the big deal is. You would have to try, not to make 600 HP.
You can not tell me if I just bolted my High Ports on my old 455 I would not make 600 HP just the way it sits.

No idea what yours made or would make. All im saying is 630hp from small'ish ci and a truly street friendly isn't nearly as easy as you make it out to be. Imo

A few combinations ago Steve C designed an excellent true street stock block 455 with Edelbrock heads that made right around 600 HP. He also was kind enough to share the results from a bunch of different manifolds he tested. It is easy to yap on the Internet about making 600 hp. and a lot more difficult to actually complete the project and achieve the number.

Funny I came across a post today from 2008 with some guy yapping about Hi-ports that have yet to see a splash of combustible mixture.... Again a lot easier said than done.

You know, that was the start of 4 mills in a row closing I worked at.
One thing, I am persistent and have a tenacity about racing.
Just like you will always be a pile. Whatever makes you feel better.
This engine is going to rock.

Would this be the block with the hole in the side that made you miss racing this season?

This was a great build. If you look it up you will see how easy it is to make or miss making 600 HP.... But easy from the couch.

Funny how you feel everything is about you, or are you the only guy yapping about a new build all the time?

A man with your qualifications should be able to find a job sweeping the floor anywhere. Not sure about "tenacity" you've been trying to build this engine on here for two decades.

Why you get away with straight up lies I don't know. I have told you I will give you 1000$ for proof I have blown it up, yet you shrivel. Just find someone from my track to back it up ? But they will tell you just the opposite.
You straight up lie about other porters, and get away with it. You have to lie about them to try and get whatever cred you think you deserve in your head, sad.
You are nothing without spray. Its your go to move.
No one in their right mind thinks it is difficult in any way to get 600HP with as cast High Ports. So I say as much, you don't like it, don't care.
'tenacity" was about actually racing. You know, the pic with all the trophies on the single 455 engine, that one.

why such a small bore on an MR1 block? Maybe KRE just wanted to show what could be done with a factory block and as-cast high ports but it was easier for them just to build an MR1 than do all the prep work to have a factory block live at those power levels?

I believe it was a swap over from a stock block.



I posted this simply because it made over 600hp on pump gas with untouched heads.

Gotcha. Would be neat to see them run the same engine with different bore/stroke combos and see if it gains any power as a 505 or 535. Of course, it is very easy to go on the internet and spend someone else's time and money!

LOL! It's an interesting build and shows what can be done with a pair of "off the shelf" cylinder heads.
