Dynomax Ceramacoat Headers

[maximus]

Just arrived today. What kind of HP & TQ can I expect from a stock L-48 with the addition of the headers,Performer intake,Summit HiPo 50,000 volt distributor,Holley 650,K & N filter,Flowmasters(I have stainless Magnaflows now,too quiet)..after I complete the true dual exhaust

Hey that sounds like my car. Duals, performer, K&N and wanting to put those headers and a cam in the car over the Winter.

I've been told,by the 1 mechanic I asked,that the Performer cam I got with my intake,is not the best choice.What is?:confused :eyerole

 

[Bob Chadwick]

I've heard that Edelbrock is good stuff. I plan to match the intake with the Performer cam and heads, which are set up to work well together. A good moderate pick which will noticeably increase the get up and go.

I'm sure other setups can get you more it's just amatter of what you want. I want a little more power in my street machine.

I just know the stock 180 HP figure is not where I want it.I dont want to get too radical,or affect streetability.But I do want more respnsiveness when I hit the pedal.I'd also like to improve handling,a little later,in the form of poly bushings and composite springs.Gotta make more money:crazy

 

[Bob Chadwick]

I'm starting to piece this together and figure I need the headers and some Stage 8 locking bolts. I also need a gasket for between the header and head and am getting the impression that I need to go with either Mr. Gasket Ultra-Seal Exhaust Gaskets or Earl's Header Gaskets.

I've been told "Percy's'dead-soft' seal-4-good"aluminum header gaskets are the way to go.Theyre made of maleable aluminum and are blowproof & reusable. I'm going to order some from Summit,I think...thing is,I have to choose between sm.blk.Chevy round or square-which is it??

 

[Bob Chadwick]

There are two sets of Chevy SBC headers listed at Summitt. WLK-86008 appears to be for the Corvette.

 

[maximus]

So are the exhaust ports round or square?

 

[Bob Chadwick]

Don't know for sure. I've read elsewhere that they are round because the recommendation was to match the gasket to the round header opening rather than the square exhaust port.

 

[maximus]

Thanks,I dont know & havent heard that.I need to know when I order the header gaskets,cuz they list both openings for a small block Chevy.Guess I'll call a auto parts dealer.

headers

i put a set of plain jane hedmanns on my L81 and cut out the cat and went true duals BIG diference in performance i also tried the corvette central off road mufflers they were too tame made the car sound like a sedan. so i put monza tips on it WILD you can hear me fire it up from a mile away and you will know when im behind you lolol:cool :cool

 

[maximus]

I have no cat either.The reason I decided to spend the extra money on the ceramic coating(Dynomax was the best deal),is that I wont have to screww around later with rusted out headers,and they supposedly keep the engine compatrment heat way lower than w/o the coating.I need to complete the forward part of the exhaust to dual,though. I've got stainless Magnaflow mufflers now-need something louder w/ performance in mind...of course it'll probly be louder with the headers installed?
