Edelbrock Performer intake manifold and header question

[opfor2]

Hi all,

Stupid question time. I’ve been told that by replacing the intake manifold and headers on my 90 K-5 that I would get a lot of additional power and increase my gas mileage. My question is is it worth the time, cost, and effort for me to replace the stock manifold with the Edelbrock #3704 performer, and replace the stock exhaust manifold with Edelbrock headers? Is it all worth it?

Engine mods

Yes, it will be, especially if you increase the size of the exhaust pipes to let the headers do their thing, you will see a noticeable difference. Add a K&N filter to your shopping list while you're at it too.

It will be worth the time and trouble, as long as your motor is tuned up and running well.

Try this site, I'm going to get some of their parts soon for my TBI.

The Edelbrock "shorty" truck hedders are not worth the money cause they are not of a full length design and are simply a fancy replacement for cast manifolds.
The Intake on the other hand is a fine piece of Vic's engineering prowess that matches the increased airflow of Holley's TBI replacement.
Port match should be observed and use a intake gasket that fits closely around the ports.
After these mods you will realize a modest increase in power output and ask yourself why you didn't replace the smallish camshaft and notably worn timing chain/gear set while you had the intake manifold off.......

make it an AMSOIL airfilter and u would be set

Shorty headers

Shorty headers are good for top end, but you'll want full length headers to get the low end torque. I've used Heddman Hedders on 2 of my trucks and never had a problem with them once.
