Has anyone tested the power gain from an open element filter to a cowl induction setup? Just curious if it actually was a benefit.
you gain 1% in HP for every 10 degrees you lower the intake air temp

this type air cleaner was originally supplied for the Z-11 impala drag cars.
also was used on the 63 NASCAR impalas with the "mystery" engine at daytona

back in the day I was a stocking dealer for KUSTOM headers. jerrys stahl headers were good but they were heavier than some other brands and extra weight on the front of a race car is not good.

OK, now that makes sense. Thanks for that extra information.
I sent you a email with the sketch

Thanks for the recollections. Pretty neat that you worked alongside Bill Howell in Vince's group. Certainly a wealth of technical know-how in that group. It does not seem logical to me to defeat the dampening properties of the harmonic balancer but obviously it was done.
the inter part of the damper where the 3 screws went thru was slotted so the outer ring could still move radially . the screws were there to keep the outer ring from coming off. I can't post pictures here so I can't show you

The earlier chevy rods were too weak and required a lot of massaging to last a race or two, the later (2.1 journal) rods were stronger. TRACO (when possible) used Carillo rods and Bartz used the 427 rods, both worked well.  i built several Daytona 500 engines using the 427 rods in SBC but they also broke and we referred to them as vbince piggens peanut butter rods

An ebay auction (#151061102844) for a Racer Brown roller camshaft used by Traco in their 215 Olds race engines. Super rare item these days. Thanks to Robert Lodewyk for pointing this out.

Text from the auction reads as follows...

This is a very early steel billit roller cam and lifters ground by the original Racer Brown in Ca. for TRACO who built 215cu.in.aluminum Olds engines for Bruce McLaren's sports car racing.

The #55 grind is considered the slalom,road race cam. This has to be one of the earlyest roller set ups because of the unusual lifter and retention system.

This is collectable or usable in vintage road racing. This is a solid roller lifter.

Buy it now and get the CAR&DRIVER also

i have a isky 2 gear drive roller cam out of one of jim halls chaparral that i picked up thru GM and maybe i should try and sell it.   Cheesy

I understand screwing the outer part of the balancer to the inner hub to keep it from coming off at sustained high speed but it would seem to be incapable of dampening any torsional vibrations from the crankshaft like that.
pick up a "chevy power book" and it shows how to modify the damer with screws so the outer ring would not come off. did a lot of them back in the day. did you ever meet bill howell your days at traco ?? i went to the TA races thru GM and bill and i would spy on the ford camp by hanging around in their pits.

You know,  after reading this thread for awhile now...not that my opinion counts for anything other than myself.  It is a fantastic looking car!  People who have lived with these cars and know them inside out,  they are to be respected.  Then on the other hand,  the original owner, who knows what he ordered and has owned, he is to be respected too.  From my own experience its frustrating to have bought my car when 18 years old,  then someone tells me "that's not original to  your car, or that is wrong."   Mine is a late 69, so I tell myself that is why.    I will say this is amazing site, with wonderful people devoted to an amazing car, and be thankful for that.
they don't respect you when you are a threat to their making $$$$.

Produce a picture and end the discussion I cannot believe you owned something 40 years with no picture.This thread has gone to long with no outside proof from you. Move on the car is beautiful in any color. Darrell
i never owned a camera back then as i was into cars and engines not pictures. the pictures of me autocrossing the car when it was new were taken by someone else and given to me. i just got a cell phone that takes pictures last week. pictures are way down on my list of things i want. i just bought a used digital camera several year ago from john hinkley.
