86vs87-93 lower intake...any difference

[Allforspeed]

i just got a free 1986 5.0 lower intake and am wondering if it is worth porting or are the ports smaller than the 87-93 intake manifolds that i have on my GT right now??

If you're going to have it ported then it doesn't really matter. LOL

On another note. I believe that the lowers are the same.

cool thanks! i was just wondering if the ports were smaller cause if they are i would assume the wall thickness of the ports are thinner thereby limiting the amount i could port out due to the less total mass

so if they are the same than out comes the grinder and out comes the welder, and here comes my super-sik home ported magic intake...

thanks draggar!!! you have totally helped me out again and again, i dont know what my car would be without this place


any confirmation from anyone else too before i grind a possibly useless intake??

Lowers are the same...it's the uppers that differ

I'd have to say that H.O. intakes suck and arent worth porting... but they might make a good boat anchor in their second life

I ran an '86 intake before I switched to the Explorer intake, and I couldn't see any difference in the '86 and a '90 I have from another vehicle.

cool, thanks guys!!! i know the HO intake sucks, but some people have had great success porting them so i like stock and smog legal so thats what i'm going to do, also its free

If 260RWHP and 12.7@107mph suck, then your right.










But I think your wrong!

i agree! tmoss was actually the guy i was refering to when talking about people making beasts with the stock intake!

tmoss, your the lower intake porting yoda: are the 86 lowers the same as the 87-93??? they look identical to my untrained eye but maybe they are thinner or thicker in critical areas??

 

[tmoss]

Yes, they are the same except for casting differences in the three suppliers I know of - the uppers differ a little with the 86 intake having slightly smaller runners in the upper intake.
