I have found many mixed reviews on the
sanderson headers cc134dp or very poor reviews about the company and their service.
I live in Canada so there are no local distributors of any performance parts. They all order from the US.

I did find a dealer local that orders from sanderson, so my question is will I regret my purchase because there are other / better products.

Application is for a 1978 corvette with a GM ZZ383 crate motor. Main use will be road track / street driving (to events).

Things that are important to me.

They work well with my ZZ383
They fit very well, no mods ( I have no fab tools / skills )
No clearance issues with angle spark plugs to melt wires etc.
No ground clearence issues
They dont leak and last a long time.

Would the CC134DP be a good choice ?

 

Yes they are a good choice for a none performance car that wanted to get away from cast iron manifolds.

You bought a ZZ383 and you want to do some track time. Long tube headers are the way to add power. www.summitracing.com

You need to think about a cross member that the exhaust passes under. 3 inch diameter pipes with an x or h pipe and some type of high flow 3 or 3.5 diameter mufflers.

You did the Spring Mountain course. Road racing is depending on the power level full throttle all the time that you are not braking. of course rpm matching your shifts to make the clutch and tranny last.

Quality headers can last a lifetime so don't buy some cheap *** junk shorty headers. I would even consider 1 7/8th so you don't have to move up later when you figure out how low powered a zz383 really is.

 

Good to hear, I have not made the purchase yet ? any that fit a 1978. Hard to know from the catalog descriptions.

 

G'day,

I bought a set of CC-158 a couple of years ago from the factory in San Bruno CA and had them sea freighted to Australia and fitted them to my 1974 coupe. I also used Stage 8 locking header bolts and have not had to touch them since. There is plenty of clearance for my Borgeson box and all the hoses need for my Hydroboost.

They are Block Huggers and there is no worry about ground clearance, as you have to have the "horizontal" part of the exhaust fabricated yourself. I bought some 90 and 45 degree mandrel bent pipes (2.5" from memory) and welded them to the stubs that Sanderson supplies. I put a "kink" in the horizontal pipes that pushed the pipes away from the engine in the vicinity of the starter on the right and the oil filter on the left.

This way I can keep the heat coming off the pipes away from the starter motor and the oil filter. Another advantage is that the oil filter can drop straight down between the pipe and the engine with no spilling of oil. When I fit the new filter, I can fill it with fresh oil and put it on with no fear of spillage.

I can't comment on the difference in performance between Block Huggers and the headers you are choosing, but can tell you that the product is well made, fits easily and requires no maintenance. I hope that helps.

Regards from Down Under.

I have 1 3/4 primary Hooker S/C and they worked with every angle plug head up until I bought AFR. Then I had to dent #6 or #4.

Do a search on Motorhead. He let them use his vette for making some 1 7/8th stainless for a very reasonable price.

Stage 8 header locking bolts are only fit on the smaller 1 5/8th primary pipes. With aluminum heads you want to buy the ARP universal 3/8ths v-8 stud kit. They come with shouldered nuts and you have to use a bench grinder to decrease the shoulder diameter on a few to clear the bigger pipes. FelPro blue steel header gaskets #1208 I think

Since you own a older vette it is time to learn how to work on them
