I have a nice aluminum high rise intake from a chevy but cant remember if it fits a sbc or a bbc... is there a way to tell? all it says on it is Pro/Stock
i am hoping its a sbc....

HotRod73 · 12-21-2006, 08:37 AM

anyone???

sick69 · 12-21-2006, 09:25 AM

if its a bb intake you'll know mainly because of its size.

bb intakes are quite a bit bigger(length and width) than the sb intakes and the are no where near interchangeable

do you have a sb in your truck or sitting in the garage? set the intake on it or next to it and see if it looks close.

**ScottH** · 12-21-2006, 10:42 AM

I believe BBC manifolds have extra bolts.
Do a search on ebay for both and compare the pics.

HotRod73 · 12-21-2006, 11:06 AM

this has 6 it looks huge though it looks like a sbc but then it dont

Try downloading it to photobucket

stepside454 · 12-21-2006, 12:18 PM

small block intakes have all the bolt holes close to inline.
Big blocks have 2 bolts on each side clearly out of line. those 2 sit dead center above & sort of between 2 ports.

OLDCHEV4X4 · 12-21-2006, 04:11 PM

Look for the fitting that comes strait out the front for the short 90 deg. hoze. Small blocks don't have that.

HotRod73 · 12-21-2006, 05:30 PM

here are the pics...

HotRod73 · 12-21-2006, 05:34 PM

i only need it if its a sbc if its a bbc i cant use it (dont have a big block) so im hoping this is a sbc

**ScottH** · 12-21-2006, 06:59 PM

You are in luck, SBC

HotRod73 · 12-21-2006, 10:33 PM

yeah but it has "Look for the fitting that comes strait out the front for the short 90 deg. hoze. Small blocks don't have that"
doesnt it??? sure its a sbc????? if so YEPEEEEE

HotRod73 · 12-21-2006, 11:44 PM

anyone ever seen an intake like this before? it doesnt have any other names or numbers on it just "pro stock" are u sure its a sbc and not a bbc???

HotRod73 · 12-21-2006, 11:51 PM

i also just noticed the back two port holes on the bottom of the intake look like they have been filled in... here is pic.... why is that??? is it useable or what???? [IMG]

OLDCHEV4X4 · 12-22-2006, 11:34 AM

SBC...It dosen't have the fitting coming "strait" out the front.
Coolant passages are blocked off in the back. Its a single plane...I wouldn't use it unless you have a small block thats gonna turn 6000rpm or more. Your gonna loose a lot of low end. What are the motor specks that you are putting it on?

HotRod73 · 12-22-2006, 11:58 AM

LOL stock 350... with exhaust... lol hahaha.... guess this wont work for me, i will try and trade it for a different sbc intake i guess

HotRod73 · 12-22-2006, 06:06 PM

so it wont work on my motor?

gflo383 · 12-22-2006, 07:00 PM

Yes, it will "work" but like he said the volume of air that intake is designed to flow if for higher reving 350's or larger cubic inch strokers etc that need a large volume of air. On a single plain intake like that one, there is an extreme loss of velocity due to its larger plenum/runner size, the loss of velocity causes a loss of low end low RPM torque. your stock 350 would have no responsiveness at all, and unless you have a bottom end that can handle 6500 RPM's it wont make any useable horsepower either.

hope that helps.

HotRod73 · 12-22-2006, 09:00 PM

anyone wanna trade for a different one or buy it for $40 bucks???

84slopwaggin · 12-23-2006, 12:30 AM

You'll have no trouble trading it off for a more usable piece.

I Am Trading For A Stock Aluminum Intake Off A 85 Iroc Z28 Plus I Am Getting $10 With It, Is That A Good Deal?

7387chevys · 12-26-2006, 11:19 PM

The intake you have is more expensive and better for performance@high rpms but if you dont have someting to use it on its worthless A performer eps(if running a squarebore carb) will net a quite noticable power gain over stock intakes..........Spacer plates also help some what 1 inch with preformer eps gives a mild yet noticable lope (sounds awesome)at idle even with a stock camshaft.
