what is the most power stock 302 every built

[Mercracer]

How the hell is that over my head? 40 years of experience and you still haven't learned that your OPINION is an opinion. In your OPINION, GT40 heads are better because they are almost identical flow numbers, and GT40 heads can be tweeked much more than P heads, but unmodified (someone who doesn't have a CNC machine) the P does perform better, this is fact, not an opinion.

And .024 seconds I don't give a shit about, but melting wires I do. Having to buy special headers I also care about. I won't argue any of your facts, I have not stated that any of your facts are wrong, but you stating your opinion (40 better than P because of future modifying potential) proves my fact wrong (stock P outperforms stock 40) is a load of crap. So I'm not wrong at all. And if there is one thing I have learned in my life (however short and insignificant it may be to you) is that even the most veteran person, can be wrong.

Take a deep breath and have a beer. Please quote 2 people if you are replying to 2 different people in the same post instead of mixing up replies to 2 people within the same post. I am the one insupport opf P heads. I meant that it went over your head not that it was over your head. Burnt wires and access really isn't a problem with P heads and FRPP headers. I can understand if you are trying to save $50 on a new set of headers if you can't afford the difference though. FRPP doesn't even sell the plain stainless headers that don't fit the P heads anymore

Despite all of my bickering I do highly respect your knowledge and experience on the subjects of these matters. I just like to piss and moan too much sometimes.

Once you add the turbo, it is no longer stock. I personally have seen those kind of times with a power adder so I am not refuting the potential with a power adder. Using that definition, I have seen a "stock" 98 Cobra motor run 9's. Nothing was touched internally to the motor.

I agree. I was going to argue with him on that post, but you beat me to it. It'd be safe to refer to it as a stock motor with a $5,000 turbo kit, but I guess that would take away from the fun.

just getting some facts straight
I want a 96 Ford Explorer motor b/c they have GT40 heads and my headers i have now will fit
But do I want the stock upper intake (gt40) or should i get a cobra or is there no difference i didnt think i found the anwsere up there so if i m being redundent

[Blaze86Vic]

The GT40 (explorer) intake is better than the Cobra intake if I am not mistaken.

[Tiggie]

83countrysquire, keep in mind that to use those intakes, you'll need to upgrade from CFI to SEFI, mostly a wiring hassle.

Just semi-OT, comparing old engine power ratings to new is kind of a crap shoot. The power ratings were done differently back then, gross numbers with no accessories and whatnot. Take that same motor with the huge power ratings and compare it to a new on the same dyno, and you'll get some rather different results. Factory power figures also aren't the most reliable so using them to judge stock horsepower is not neccesarily useful.

moet of my stuff isnt opinions more fact. What has worked or what is. On a flow bench bigger flow numbers dont always mean more power. The head with higher air speed a better combustion chamber faster burn is going to win. Best bang for the buck ported E7s with stock valves flow 220 at .5 lift actually that dosent show it alll becsause they will flow more at every lift point. At that point go with a GT40 tubular intake or a P intake.. I f you can get the intake to flow 220 which it might need ported too. But will say the intake flows 200 yo ugot 400 HP. What are P heads or 40s going to cost?
All stock E7s maybe 100 or less I do the port work for 500. Bigger valves, better springs, retainers, studs, maching for studs is extra. A carb set up will get you 50 hp more than SEFI for less.

Dyno results can be tweeked all over the map. There a huge threads on this in other forums.

Adding your numbers up gives a person a $850+ investment including valves/ hardware and shipping. You do not appear any less costly than Power Heads.

There are good complete Explorer motors for $500 or less. If you sell the intake for $200-250, you have $300 or less invested in a long block. If you just need the heads, it is easy to sell a good shortblock for $150. The throttle body can be sold for an additional $50. I have made money by just selling the intake and shortblock. I had a free set of heads and extra money in my pocket to put towards the heads when I was done. That leaves you an investment in a set of heads that can give you 325+HP on a 302 or 400HP on a 351 without porting for $150 or even less. Springs and hardware are cheap and you already have larger valves.

If you just want to buy a set of used heads, they can be found for $200-300 a pair depending on condition or a little more if someone freshened them up already. The most I ever had totally invested in a set of P heads was $600 including shipping and that was brand new castings with stainless undercut high flow valves and new high lift springs with new hardware.
$600 included a fresh cut on the seats and valves and assembly.

It's cool.....

yeah i know about the wiring but someone told me i can just use a box MFI wiring harness from like 89 or 90 or 91

I would say the old Shelby Mustangs. The Boss 302 was under rated pull there rev control box and they would fly.

Shelbys had mostly 289 Hi-Pos, not 302s. in '67, the GT 350s had a 306HP version of the Hi-Po 289, while the GT 500s got the 428 with dual quads. All pre-67 Shelbys had the 289, and the '69 GT 350s had the 290 horse 351W. The only year the Shelbys had a 302 is in '68...rated at 250HP.
And I don't know why the Boss 302 wouldn't count in the "which 302 has the most power" debate if we're talking about Ford factory power.
And the Boss 302 wasn't Shelby. In fact, one of the many reasons that Shelby got pissed and left Ford was because there were SERIOUS rumors that the Boss 302 program was funded by money funneled from his program behind his back.

All pre-67 Shelbys had the 289, and the '69 GT 350s had the 290 horse 351W.

The 70 of course had the 351W 4V also. The 70 Shelby was the only car which got a 351W 4V motor for 1970. All other 351 4V motors were Clevelands.

You can, yes. There is a guy on lincolnsonline.com that recently converted his 1983 Mark VI from the old school CFI like you have to a multiport injected SEFI motor. I don't know what exactly he used as a donor car, and he said it was a lot of work, but it certainly can be done. He ran this setup on his otherwise stock rebuilt 1983 motor, so the cam used in that motor apparently behaves OK with the EFI system.
