sup all...
my dad has some old school hook up wiht this rotar head in south tucson ... and scored me a 13b 4 port intake manifold witt a holley 600cfm adapter plate on the top for free....


question is: i have my engine mildly street ported ..... what do i have to do to get my holley to work right on my 7?..... port the intake?... but ive heard i will lose low end if i make it flush and smoothed

i honestly dont have any idea what im talking about haha.. so any help would be good

thx

 

If you have a 13B 4 Port,

and the Intake is for a 13B 4 Port.

Then just put it on. Is the intake aftermarket?
If it isn't, then it's probably what you're running now.

You don't have to modify an aftermarket intake.

 

what about matching the holley to the intake.... isnt there gonna be a difference?

 

hmm no answers? sh*tty

 

Holley on what intake?

Stock with adapter?
Aftermarket?

Oh, and what size Holley?

 

this is what i got ( see pic) stock intake wiht a adapter for a holley on the top and my das old holley carb im taking ... and my engine is street ported...


this is what i got

 

You should try it.

I have a Holley adapter that fits a 12A manifold. It keeps the runners seperate though. This is good incase I machine some holes for it to fit a 13B carb stud pattern and all the runners will be seperate. Or I could take peejay's advice and cut a channel between both primary runners right under the carb. I dunno.

 

there have been two recent threads addressing the issue of porting a stock manifold ... the consensus is "no" ...

upgrade your fuel system (pump + regulator ~ actually, a dual inlet pipe would be a good idea as well) and try to tune the carb. i guess a 600 should enough for your streetport ... but only time and tuning will tell.

 

thx.... but i need more input! more input! johny 5 need more input!

so please anybody els with some two cents to give............. give!

 

no more input?

 

In my exprience with holleys i would never put one on any of my cars, they are crap,
fit a webber or go injection.

what else do you want to know?

 

well iv gatherd that matching it down at the bottom of the manifold is bad....

so do i just rebuild the carb, upgrade my fuel pump, add new gaskets, hook up my remaining vac line (from dist.) and cap all the others,

no porting up top?

just bolt on and add fuel ?!?! haha

sorry if i sound stupid i just dont wanna FU*CK UP

this is my first time dooin any of this... im good mechanically but i just like to know what to do to get the best out off this....

i want a nikki but this was free sooo... im gonna do it

 

Throw it on and squirt some gas. That's basically all you can do at this point. Then, if it's not quite right, you can try other stuff.
