the lower intake is what is really restrictive....im not sure how much it could support though. probably not too much without a port job on it
if u can find like a cheap gt40 explorerr intake that would help out alot more then the stock, i think cobra intake can hold up to like 300 not exactly sure
An unported "select" stock intake supports ~230-240HP if you get a good engine combo together. Port the lower and I've seen the stock intake support ~260HP. Get crazy with cutting the upper up to port it, and you might get ~300HP out of it if your good. All these are naturally aspirated numbers and just my opinion.
All i know that is with the stock intake and mild porting, I couldn't muster up anything better than a 13.5 at the track with my afr's and afm cam. My new Holely intake will change all that, however.
well heres the reason i ask. I have spent an enormous amount of time hiding my wires and smoothing the engine bay and it looks killer. the car is currently speed density, but i do have a A9L mass air setup for it. But it looks soooooo clean with just a small billet air filter attached right to the throttle body. I also have several stock intakes i was thinking of show polishing, but before i did i wanted to know if it would be a waste of time. Sounds like it is. I just sold my Track Heat, now i am trying to figure out what to get. That and how far I can take this speed density motor using nitrous.

I don't think horsepower is the issue with the stock intake. The runners are longer and help to produce more torque and a wider powerband that ends earlier than a short runner intake. For a street car most people including myself absolutely underestimate what a stock intake will do. If you port the lower they work surprisingly well on mild cars. Even after porting the smaller ports help with intake charge velocity and really produce excellent low and midrange power. Tmoss should know, he's ported something like a million of those things and people still send them.

Sure, why not? If I had an 1986 SD car with flattop pistons, I would go with a nice set of ported Thumper E7s, a Tmoss lower and stock upper intake or if $$ allows, an aftermarket... like an Edelbrock Performer or similar [something idle - 6000] 65mm T body... all of which would probably come close to maxing out the stock 19 lb injectors... plus all the bolt on stuff .. headers.. exhaust..etc... then, a GOOD posi unit, some 3.73s or 4.10s [28" tire on the 4.10s IMO], 26x10" ET Drags. 255 L/hr fuel pump, and a good quality wet nitrous kit with a window switch. Little bit of suspension work to make it all stick off the line and you'll be in the 7s in the 1/8th mile..
Depending on the amount of nitrous used... it could have the potential to go upper 11s easily... maybe quicker if you're brave and run the 150 shot..

I will have images of molesting stuffed animals in
I had to run a 150 shot on my stock 86' motor to get a 7.90.
I had a gt-40,65mm T-body and full BBK exhaust w/Flowmasters.
I think it was because of the crap 86' heads and cam.
