Shift RPM?

[Tim Hensley]

i have a DLS 210-210 roller with champion iron heads,and intake,complete forged bottom end and iron center caps.A BJM balancer and JW flexplate
I’m in Hawaii and I’m sure someone has a dyno, but I have not really looked for one .
but where would you shift it at if your were to take a guess?

[Steve Wood]

5800

[Tim Hensley]

Thanks I like that number
I had been shifting 5500 but my butt dyno said it was pulling past that.

You could always take it to the track and see what it likes.  But I think Steve has pretty damn close.  I know with my 224/224 cam I gained 2 tenths shifting at 6400 compared to 6000 but my lifters weren't up to par.  I can't wait to hit the track and see what the car likes!

[Steve Wood]

I learned by experience.  My PTE 210/210 was still pulling hard at 6200 but it would suddenly go BANG scaring the heck out of me.

I quit driving it about 3.5 years ago because it smoked so much which appeared to be the valve guides.  William Avila and I swapped a new set of heads on in June.

Here are a couple of pictures that show why over revving is bad..and, it did quit smoking with the new heads..LOL  the wages of sin are expensive.

Wow, that is crazy!  I can see why it smoked.  Were the springs binding at the high rpms?

[Steve Wood]

Don't think so.  I think the dampers lost control and shattered. The valves had not hit the pistons.

I think mistakes were made by the original builder that were exposed when the roller was installed but the over revving finished them off

Every set of heads I've ever built with those stupid plastic lined seals have leaked and smoked.


I won't install a set of those ever again...   if a customer insists on using them.

Did you replace the old springs with beehive springs?

I bought a complete set of heads from Billy Anderson that had about 400 miles on them.  He took them apart, checked them out, and lapped the valves.

Billy does not like Beehive springs.  I recalled he used them a short while and then would not use them again.  I forgot why he does not use them as that was quite a few years ago.

We placed the single GM shims with 0.040" Cometics when we went back together.

The heads we pulled off did not have the exhaust valves replaced so that obviously chewed up the seals on the exhausts, but the intakes were popped off and that is where the oil went.

Billy is the one that sold me my roller cam kit with beehives.  That haven't given me any issues.

[earlbrown]

I often hear the ''I won't run beehives'' story.

...but I've yet to see anyone with an actual problem post about it.


Most of the time the negativity seems to be because there's only one spring.   You know, like stock springs on a LOT of cars.

5800. 1-2 shift on mine goes off at about 5300 and the 2-3 shift at 5800. I use 130 lb valve springs with this 212/212 flat tappet. I have it on good authority that AC convertors couple better shifting them higher on the 2-3 shift. My trap speed concurs.

Billy used them and then stopped.  He posted about problems with them but I don't recall his issues.  Some of us consider him to be somewhat legit in the buick business   Good thing about Billy is that he does not care what others think unless they are consistently faster than him.

Dan sent me PAC 1200 and I set then as instructed.I have a set of Johnson short travel lifters.
What are the numbers on PTE cam? I had it to the track last Sunday forgot my laptop so no data,I just swooped out my Edge LU to a Extreme Automatic NL.car went 2 mph faster,it use to shift at 5500 so I had set my 2step at 5700,1-2 shift was under the 5700 but it bounced off the rev limiter for the 2-3 shift.I was going to change the governor out but I’m going to raise the rev limiter.and see how it goes.the bottom end is a full forged rotating assembly.so I will report back next outing in two weeks.
