I thought 4.75 stroke was the largest you could put in a standard Block.

Correct, I thought you said you had a raised cam block, if so 5" crank will fit.
My standard height block fits a 4-3/4 crank nicely. A couple cam lobes though are at .060 from hitting the rods.

Ron Flood at Cedar Machine in North Branch , Mn. would be a very good choice.
He may well be Jericho's one man shop......he is one of the best around and relatively unknown by most measures.
But he breathes precision and has a lot of Hemi experience.
He has the fixtures and tooling for most blocks.
And is a stand up individual.
It would be worth a call.

A screw blower is how you get power without the destructive RPM that chews up your valve gear.

I do not, and will not go through Ron. My second choice (if I had to) would be Line's. They do very nice work, and Lance is as hard of a worker as you will find. I have a few friends that go through Lance, and all have been happy with his work.

Yes I’ve got a raised cam KB Block and always thought that the largest stroke was 4.75.

I think sticking w/ the single 4 Indy manifold is best for what you're describing. Add a fogger and have some fun w/ it when you want. Bracket race it NA otherwise.

It sounds like to me you want the WOW factor when someone looks at the motor or the car and a blower will give you that, there is a Duster in town like that. If your car was going to run at the track only a 605 with two carbs on a good intake and lots of Compression and good gas and I would pick a Hogan intake can make you a ton of horse power for an easy 9 second pass. Most of the racers around me run NSS. All run in the 8s and some have run as low as 8.20 in a Super Stock A Body that came apart at just over 1100ft doing this. This car had the special set of Aluminum heads from FHO. I was wondering how much spring pressure are you going to run and what valves and what valve seats. Most of these guys have bigger that a 750 lift cam, all but one guy and he runs 890s with the lift you have. I was going to say you will have to check things on the motor each year but since it snows early were you are you will have all Winter to do that.

The heads have Copper alloy valve seats, titanium valves and not sure on spring pressure

When I got the cam from comp cams they sent all necessary parts to assemble heads.
MCH put them together

Kevin, I've never done anything with a raised cam, so I'm no expert. But guys are building 4.75" stroke hemis without the raised cam. I would have thought you could go 5 " with a raised cam?

It’s to bad I didn’t know that before I started the build, I would of ordered a 5” stroke crank.
But I’ll run what I have and make the best of it.
Plus I know if I go big boost it’ll handle the power.

With the cam raised in the block I believe it requires a special cam core and also a belt drive.

That's correct on the special cam , 48* and belt drive. I think someone makes a gear drive also. Any crank over the 4.5 gets hard to find a lot more expensive and longer lead times.

KB makes a gear drive, Jessel makes a belt drive and I never knew anything about a special cam.
Ken Black never mentioned it when I ordered my block.
I’ll need to shot KB a email and find out for sure

Thanks for the info guys
