Okrasa / Judson

[vwhelmot]

Has anyone ever used okrasa heads but without twin carbs instead modified the manifold to accept a Judson?

You would get better power with dual carbs than a jusdon ..judson is basically for stock engines and looks and to be like look how much I spent on my judson... can you adapt one with okeasa sure can but you will over drive the judson and next min a rebuild and rebuilding a judson is vary vary expensive ...you will get more power with dual carbs and save thousands ....but if that's what you want okrasa heads with a judson hey to all reach its own if that's what you want do it but the power is not what you think it will be ...I remember hearing a guy who had a stock 36hp engine he dyno it and than he installed a judson and dyno it and his 36hp with the judson made less hp than when it was stock like what ?? If you want to show off to say look how much money I just spent than a judson is for you... I would run a judson only if it was 100% rebuild and given to me for free lol thats when I would install one on my engine other than that I would pass dual carbs seems to do better ...if you want a supercharger the pepco/ speedwell is much better than a judson but than again those have a limit as well ...

I’ve been running a Judson for the last twenty years. I fully rebuilt it with a new T6 rotor, vanes and bearings etc so it’s all good. The motor that it’s on needs a rebuild , so far I have nos b+p, it will be running a repo ww okrasa cam, new lifters, an original 64mm okrasa crank, original okrasa heads, full flow oil etc etc.
Just wondering if anyone else has adapted the manifold really.
I will make my own manifold but it’s nice to see pics if it’s been done before.

Well….. if it’s not been done before we really don’t know what the outcome will be do we?!
I’ll let you know.

It’s been a long road to get here. Much modified and all ready to fire up.

I like those end castings ..do you happen to have more pictures of them and how you modified them ....

What a killer set up!

If you haven't seen his build on Instagram you're missing out. The finished project is extremely EPIC, but if you saw the details in that setup....

I've never seen anyone do that to that standard.

Thanks very much

Some more build pictures. I would later find out that my original okrasa crank was not 64mm as advertised but 69mm instead so that changed quite a bit of my original build idea. I ended up using AA two piece lifters, cb pushrods and spacing out the barrels to get my compression right.

I used late a model manifold which I cut up and made new mounting flanges and match ported to the heads.

I made my own bigger bore heater boxes that can be disassembled.
