Topic: RC Engineering

[ukshane]

I started a thread in the for sale section to try to get some insider info about this extra engine I've got.  They guys that already responded suggested I post a link in this forum as well.  Any insight would be appreciated.

PMed you

[Sam Green Racing]

Going off todays prices and what I have just paid out for a big bore MTC block and liners, a new RC block will cost around $1000 (at a guess) when they go back into production (which will be soon).
In respect of the rest of the motor, you're not going to know what's in there until you pull it apart.
Once you have the head off, just measure the bores in MM to determine the capacity, it will be near enough with a simple rule.
Post the measurement on here and we can tell you what size it is.

Unless it's a stroker

I'll stroke you if you're not careful.  off to the supermarket now for my shopping  and beer

Yes Daddy Green. No Daddy Green. Have fun.

I looked at the pics in the link. It is an early head based on the cam towers etc....1971 or 2 I'd say. Exhaust guides need to be replaced. I'm sure the intakes too. Whole head should be rehabed. That block can be resleeved for nice, light modern pistons.

[Greggo]

Those blocks are going back into production!?!

 Mike, you are still going on about RC Pistons being heavy... I am thinking you must have been looking at early ones, everybody started somewhere.. Evidence suggest (and I have posted weights on here) that not all RC pistons were heavy.
 Plus you don't aways have to resleeve to change pistons..

Yes Frank....I am. The last 71mm RC piston ( #270 SS)I got weighed 237.5g bare (with gas ports). Those were Arias I believe. The JE 71mm flat tops in my bike weigh 185g bare....plus the pin and ring pack are lighter. The Wiseco 70mm piston CycleX sells is 169g.  50 grams (for the pistons alone) is a lot Frank especially when you consider it is swinging off a 15mm pin. Just my opinion.

[754]

 I assure they had more than one version..
 I suppose if one of the people other porting shops got a hold of one of your early heads, they would have things to say about it.. But naturally things progress as time goes on..
 Can't take away the records that RC or their products set..

[754]

 I got to ask Mike, would you really run the lightest piston you could find on a blown nitro motor?

[MRieck]

No. But I also wouldn't run a 15mm pin.

  I was wonder the same thing.

Murphy, do you remember that pin that Rick showed us ? 

[Bill/BentON Racing]

Frank,my RC 970cc piston weighs 219g,my CycleX 915,155g,I KNOW which one your rods will play with longer!
Weight kills rods,plus like Mike said much lighter and better ring package.As you stated we all learn! Bill
Did you get with Greggo on Roto-Faze? Pretty neat unit,have no info,anybody?

[754]

 Hey they had to work with what they had, bet no one complained about 15mm pins the day they broke in the 7's. I am sure that a few pistons made for fuel use found their way into motors on the street.
 Bill the mag is on its way, I wood have asked about the RC dist but you said you were keeping it.. RotoFaze is still around he builds flathead stuff, which this probably is. looks more dist than mag, but as long as it works its fine by me..

I can't say to much at the moment Gregg but it is in the pipe line.

Frank....a solid 15mm piece of tool steel would hold up anywhere. My point...and previously explained philosophy...that has been adopted by all manufactures...is that light is right. I am sure things not meant for the street get there. I take nothing away from RC's accomplishments...they walked the walk.
 Yoshimura (which I always preferred) had an attitude that mimicked the Japanese manufacture to this day...and they were around before Russ and are still in bike racing. Drag stuff was all heavy, clunky stuff THOUGH they do appreciate the idea of light now. Placing 1,2,3 at Daytona (for Yoshimura) in the 70's isn't a mean trick either. They have set their mark as well.
 Personally I don't care about stuff almost 40 years old. It is nice and nostalgic but it is over. I'd also say my first heads probably weren't bad because I copied Branch, RC etc. I just paid more attention to detail.
 My big point is while nostalgia is great it is exactly what it is....old....and clunky with skirt to wall @ .004 or 5 etc.
 I do truly appreciate your comments regarding my block.....I wish you could hold one in your hands.
 Anyway....no hard feelings at all BUT I just wanted to explain myself for folks who may not have known my position.

                 Why ?  Not enough info ?      Can't be top secret......     If JR decides to produce new R.C. big blocks, i hope it's a way better design than the old R.C. big blocks.       On a side note, back when i had a visit with JR, at lunch him and i talked about reproducing some R.C. products like the R.C. headers, big blocks etc.  It all boils down to $$$$ and what the market demand is.  Mike would know that for sure on the big block scene.

You suprise me Mike, I,m with you.
RC produced cutting edge gear for our bikes at the time.
Time has moved on and so has RC Enginering.

How about another run of the old 'RC Engineering' logo t shirts?
For some reason over the years mine seemed to shrink   

[Bill/BentON Racing]

Still rather have a MR(Motorcycle Racer)Mike Rieck block!!!!!!!!!!!!!!!!!!! So much BETTER!!!!!! Bill

[754]

 There is 3big ends in this pic, two are Yoshimura..

[voxonda]

The rods from Yoshimura were never intended for engine seizes bigger than 810/823. They never made kits bigger than that. Ran them for years in racing engines of 750cc, and little over, and never ever experienced problems. Wished I never sold them. Agree that putting a 970 piston on them would create problems though.
