I've heard some strange things on this forum, but never the "like single patterns for the sound" line.

As for the oil fill tube- there are other ways to get oil in an engine.

[vinniekq2]

you can tell by the sound if a cam has a dual pattern?

Another intake option I may consider is an Edelbrock C-26 dual quad.

Trying to achive a 60's hotrod look & sound with this engine - it's going in my 59 Chev pickup

if you want the real sound of he 60's era you need a solid lifter cam in a wide 114LSA.
use Crane Cams cam #110941 It will have the right sound you want.

Get a dual plane off a old 327 and use a carter carb.
The edelbrock C3BX is right out of that era.
So is the Weiand 8016

The Street master is a 70's disco era intake manifold.

60's was solid lifter cams dual planes and dual quads.

You will need to recuve the distributor. bigger valve lash ='s more 60's era solid cam sound.
smaller valve lash ='s rougher idle.
do not go looser on the valve lash than +.006" looser
than the crane cam card spec. you can go up to .012" tighter on the lash.
the lash spec is .022" hot. so,,, you can vary that from .028" to .010" and get a different sound from the cam.
This will not harm the cam or your motor. but will adjust the idle sound to your liking.
adjust the valve lash once a year.

Cool - thanks for the tip on the old school intake & cam

Just to follow up, I got a reply from Comp Cams about getting their 280H Magnum with a 112 LSA ISO 110:

Tracey, we can help you with this for sure. We can grind that on what
ever LSA you would like. The 112 LSA will smooth the idle out a little...
And push the power band to the higher RPM side. It will also lessen the detonation threshold.

How much RPM are you looking for? Let me know and we will go from there. Thanks.

did you talk to Ryan Hart at comp?He takes awhile to respond,,,

Strange deal, Streetmaster intake with 200cc heads?????
I've used a Streetmaster in the past. They are excellent for idle to 4000 due to the tiny little runners, but run out of breath up in the range. It's almost like the manifold will be signing off right when the heads begin to come on.

[AutoGear]

Ive seen a couple non airgap RPM manifolds modified for a fill tube with the EGR in the tube (I think). Cool deal. I'd use a 300-36 manifold and a Holley. Or go Dual Quads. The 60s are my favorite era for Hot Rodding. You went from 283s to 350s; dual quads, tri-power, superchargers, turbochargers...Its wide open. That street master has to go though. As far as the cam; Im a UDHarold fan, or Id call Isky but thats personal preference. Dont forget the CherryBombs!

[vinniekq2]

Ill take that street master intake. Like tech said,its great low rpm intake,my choice for mileage builds. not my choice for power

Hmm, so the streetmaster is incorrect for a 60's looking engine. When did Edelbrock make them?

I would have never guessed a single plane would help MPG

Wanna trade for a dual quad intake? I think my dad has a couple old AFB's in the garage

This is it

[vinniekq2]

torkers were very popular back in the early 70s/tarantula/scorpion,,,,,,back in the sixties,the z-28 intake was around but expensive,offenhauser had some unpopular intakes back then. The only intake I currently have is the holley street dominator,and its not impressive or retro.

[ap72]

It may not be exactly period correct but a Torker intake looks very similar, can be picked up super cheap, and produces decent results- it's not as good as an RPM intake or something of that nature, but it does still have the look your after.

The current engine has a torker, but it's on an Olds 455 that I installed in high school. It has a bent rod, so I'm replacing it with a 350. I would like to keep the Olds, but I can't justify the 9-11 MPG. (My 350 vette will get around 17 mpg cruising at 65) + rebuilding a sbc is waaay cheaper. The Olds also had an overheating issue I just couldn't fix either.
I am going to use the current Olds TH400 though with a Summit adapter
