Heads? A/C delete? Smog Pump

McMustang5.0 · December 14th, 2009, 07:54 PM

So, for christmas I'm buying myself some new heads. I found some E7's ($100), Newer stock ones ($50), GT-40's ($150) and some GT-40P's($200).

I would like to get the set I buy rebuilt, ported & polished. Which one's would give me the most gain (over my stock heads) for the least amount of $$$? Which could I run nitrous threw without a big BOOM!

Also, I want to get rid of my A/C, can I Just remove it and get a shorter belt? Also my smog pump is disconnected from the tubes and stuff but the belts still wrapped around it, can I just remove that and get a shorter belt?
Or will I have to fab a pully for both because the clearance between the HB and other pullys?

Thanks

Shorter belt, and get the gt40/gt40p heads, e7 heads are garbage. Not sure which would be better between the gt40 and gt40p's tho.

flyin ryan · December 15th, 2009, 12:52 AM

gt40p's flow slightly more... but only certain headers fit them good

completely remove your smog shit and your ac shit, you don't need any delete pulleys just measure and pickup a new serp belt.

one thing though, on the back of your heads are a port for smog.. you need to bolt those two holes off with a bolt when completely deleting the smog pump and stock catted h pipe fyi

Ok, well I have hooker headers on my car now, would they bolt to the gt-40p's? Or do i need to get some better headers?

Alright!

Also, i'm looking for a good battery for the cold wintery months! any suggestions?

Gt40's are your best choice. But in my opinion you should put the money away and try to find a deal on used heads. Trick flow's, AFR's, canfields, ETC

My ported E7's will be for sale very soon.

When I bought a battery I just went to advanced auto and got the one with the highest cold amp's rating, cost me $90. I think it has 1,000 cold cranking amps.

If you want a good battery get an optima they are the best. Stay away from e7's I don't care how much they say they are ported, shit I dont care if they were solid gold. Saving like someone else mentioned for a set of used trickflows is not a bad idea.

the fuck why? I hate people with their "P heads are ghey cuz you need 900 dollar special headers" internet shit. 90' spark plug boot, they sell shorter spark plugs, heat sleeves for the plugs. FUCK going slower cuz someone on the internet told you to find reg gt40s when theyre harder to find and sell for more

95StangMX · December 15th, 2009, 04:07 PM

Is there much difference in the gt40's and the 40p's? I have never ran the p's. Had a 92 lx with gt40 heads and intakes and a b cam that ran pretty good.

93hatch · December 15th, 2009, 04:10 PM

flow, they burn cleaner, therefore make moar powa

95StangMX · December 15th, 2009, 04:16 PM

what I am asking snatchy is do you know the differenc in HP? Is it a big difference or are you talking 3-5 HP (I can get one of those turbonator air filters that will give me 120HP to make up the difference if so)

93hatch · December 15th, 2009, 04:27 PM

specificially? nope, but Ps are much easier to come by. Ive been trying to sell a set for like 2 months

flyin ryan · December 15th, 2009, 10:21 PM

Out of the box the GT-40P's flow better, burn fuel more efficiently, and have a smaller combustion chamber (higher compression), than the GT-40 Irons. The GT-40 Irons you'll usually find have a better valvetrain capable of taking cams with lifts somewhat higher than .500 whereas the GT-40P head stock valvetrain should not be used with cams having a lift over .500 unless you like valvespring bind (which you don't). There should be no debate still out there on which head is superior. The GT-40P is by far the better head, no ifs, ands or buts.

get the sand out of your pussy. I meant gt40's in general. No need to get your pretty pink panties in a wad because I left the "p" of the end.

the p is for penis
