still running a factory 302? WHY? Go 331
Well, I had a decent stock motor that had 120,000 miles on it. I said screw it...my 92 now has a AFR 331 with x-303 and was a AOD and now sports a Tremec. For all the mustang owners out there that have stock blocks...get rid of them.....the 331 gives awesome results.....if you are on the west coast go with
www.F-P-S.com. i got my 331 with ross pistons and forged rods for 2300 and some change. 331 (9.0:1 COMPRESSION) AFR 185's X-303 (4 DEGREES ADVANCED) EDELBROCK RPM INTAKE 70MM TB 75MM MASS AIR 24LB INJECTORS ADJUSTABLE REGULATOR TREMEC WITH 4.10's 1 5/8 EQUAL LENGTH SHORTIES HIGH FLOW CAT H-PIPE WITH HOOKER AERO CHAMBERS TRACK TIMES THIS SATURDAY....HOPING FOR 13.2 - 12.7'S ON STREET TIRES......

Good luck at the track. Since you'll be on street tires I'll be more interested in your mph than your ET.
Have you had you Stang dyno'd? If so, what kind of numbers is it pumping out? E

Hey, not to burst your bubble, but you are still running the stock block too buddy. (unless you dished out enough cash for an R302 block)
Quote:
can i ask you something? Why the X303? The rest of your combo looks great, and then you settled for ancient technology in the cam. also, if you had the money for the motor, why not pour some into the suspension and really race that thing. I'd be pissed if I just spent 5-6k on my motor and someone pulls up in a stock headed coupe on slicks and runs just as quick as me at the track but thats just my opinion, i could be wrong

fiveohpatrol , what was your 60 foot when you ran that 12.9? You must've cut a good one. Was it on slicks or street tires?
Thanks

89 Cobra LX, i was using hoosier 26x10" slicks. I was still spinning them a little bit though because the track was really cold.
That run I had a 1.72 60ft time, so yah it wasnt bad. ballistic_331LX , I just read back through my post and it may have seemed like I came off as kind of an ***, sorry for that, just throwing my thoughts out there

How about breaking down that $2300 for us. If that's a complete long block you've got about $1700 in heads and intake alone, which means your still running a stock block. If $2300 was just for the short block, I might see you having something other than a stock 302 block such as an R302, but then with the other parts added on to it I would be looking at mid to low 11's on motor, not high 12's - low 13's.

stock meaning factory long block chucklehead
i know i have a stock production type block...i was meaning rotating assembly......a stcok block is plenty stong enough for many applications...the only thing the 302 could have used from the factory was 4 bolt mains. anyways the shortblock balanced, blueprinted and assembled was 2300 dollars. the rest of the motor was a couple more grand. I think it was all totall budget and still has killer parts. The things I bought that i wish I had not bought was the 70mm BBk thottle body......that things whistles louder right off idle than a referee in a basketball game. I also bought that 75mm mass air that is plastic and is a piece of crap, So basically it is a fake 75mm....anyways....street tires will be put to the test this saturday......

Hmmm.... 331, or a turbo kit? All those with 331's get rid of them and just get a turbo kit for a 302.
The bottom line is the 331 will give you about 30-40hp over the stock mill. If it's worth a couple thousand to you, go for it. It's a nice setup. |

If you're going to freshen the motor anyways and a power adder is in the picture.. the 331 is the way to go. When I was researching what I wanted it was pointed out, by more than one source, that the 331 actually had a better rod length to stroke ratio than the 302. That's why I bought my 331. The ratio on the 347 isn't too good and would wear out alot faster, too much pressure on the side walls. For a budget build, I have nothing against a 306. Up the compression, good heads and a good cam... strong combo.
In this day and age, alot of 5.0s are in need of rebuilding. |

If I had $2300 US burning a hole in my pocket that I wanted to spend in one shot I'd get a paxton carbureted blower setup, I'm betting that would net me more power than going 331 and I wouldn't have to pull the motor to put it on!
Don't get me wrong, I'll probably stroke my motor when it wears out but that could be several years yet (I hope). The stock 302 has plenty of power potential on its own, it's one of the toughest motors out there.

anyways...i have built small block chevys and now this small block ford.....the chevy makes lots more power with less in to it thats for sure....as far as stock prodution 302's i think they are garbage......especially the heads! I know alot of people with LS1's and that is a pretty stout motor from the factory...especially when i seen one that made 322 to the wheels with 2 mods...air lid and a exhaust. gotta keep the fox body guys on top and keep the cubic dollars rollin

A definite possibility, but w/ only 12+k on my original 302 block, I think I'll spray some giggle gas, if it blows, it blows, and then I'll step up the cubes.

2300 bux for ~35hp. Sounds like a pretty shitty deal to me.
Why not get an intake that actually flows good for that big motor you got? You could have put in 11:1 compression, run a 306 saved 1500 bux and had the same horsepower. Think what you could have bought with that. Suspension, Tires. Then you could goto the track and not have a fully built stroker running 13's on street tires. Thats kind of a joke in my opinion.

Oh yes, the stock 5.0HO is garbage alright. What a dumbass statement. Let's see, an engine that makes solid power for the era it was in, and lasts in most cases 150,000mi or more before it really needs a rebuild. Yep. Sounds like garbage to me. Next time I see an tired, clapped out old LT-1 with 100k on it, burning oil like no tomorrow because of it's 10.5:1 compression, I'll be sure to tell him be glad he doesn't have that garbage 5.0L. I'll have to wait a couple years to see the LS-1 in the same condition, which I fully expect it will be. Next time I hear about an LS-1 bending all his pushrods from shifting too high, I'll be sure to tell him to be glad he didn't have a 5.0 that would have put up with the rev limiter all the way down the track.
So the heads are also garbage? So what if they don't ventilate mineshafts? The stock heads will get a Fox into the 12's if the rest of the car is setup for it. Why does everybody think if your heads don't flow 240cfm that they are junk? If the 5.0 had the 10.5:1 compression of it's GM counterparts you'd be talking 260hp from the 5.0HO. Not earth shaking, but with a home port job and a better intake on that kind of compression, you're now talking 280hp. Guess I'll take reliable, long life, good performance, and ease of modding over a super high output dung pile. |

Why is everyone hating on my boy? The 331 is a great motor, I love mine. As for it being a shitty deal, well when my crank snapped and the motor grenaded it was the only choice. I know Ballistic 331lx and his car is a street car so like me I really don't think he wants 90/10 struts and 50/50 shocks. And he didn't say that it runs 13's he said that was what he was expecting. You know not being all caught up in it like saying I'm going to go run 11's on my first pass out. I mean he did just put it together 2 weeks ago. He's just not setting his sights too high. If he would have said I'm going to the track and I'm hoping for low 11's you guys would just be knocking him for that. I know it may have came off like he was bragging or something, but I know him and I think he is just happy with what he's got after running a 302 and AOD. Think about it.

Were not hating on your boy, dawg. He was just saying to ditch your 302 for 331's and we were saying its not the best deal for the $. IF your looking for a stroker though the 331 is great. I bet its a great increase, and going 12's on steet tires is pretty awesome. best luck to ya both.
