Well i just got back from summit racing, they have jet chips for the 300 L6 now, seems like they have them for all the years as well. I just searched for ford 300, then i selected ford from the results, then f150 truck, and 4.9L/300, and then 93 (my year) the first chip I checked fit a 96, so it looks like the chips are here. I dont know what all is involved in the installation, or if anyone has mentioned these before, but YA!!! haha. They are 220 bucks, but i think Im going to call and see how hard the installation is, if its simple, there went my next paycheck.

 

i believe there a piggy back chip from venom if i remeber right my friend has one on the way ill let you know.

 

Not trying to tell you not to or anything but, if your fairly experienced when it comes to automotive stuff in general i'll bet chevy rockers or a new cam would probably be better for performance than a piggy back chip would. Plus jet chips usually (Always) I think require a 160* t-stat which is just absurd especially for a efi motor. That and there is no way you could keep a stock that cool anyways. At least i doubt it. Plus if you can't get dyno results from them then it isn't worth the money i gurantee that. Superchip offers a chip that supposably adds 14 hp and 31 ft lb i beleive for the 300s but, they still won't show you a dyno sheet. It's kinda like ricers thinking headers actually add 20 hp to there rides because, the box says so. Anyways you get where i'm going with this by now i'm sure. G/l with whatever you do and if you do end up getting a chip for it post results telling us how you liked it.

 

well, I dont know that Im going to buy 1.
I know I can keep my motor that cool, I have an electric fan, and if its on, its never gone past the N in Normal.
As for chevy rockers, I thought there were dyno numbers that only showed a 2 or 3 HP gain, and cams, I dont know but it seems like its just asking to break something if all your doing is increasing the RPMS, but i was wondering, Has anyone used these chips, and if so does it move or remove the top speed limiter, 95-100 Just isnt cutting it when all my freinds are doing 110-120, I know the motors good for it.

 

I've not seen any anecdotal evidence on any forum that these chips work.

Also, 80 seems pretty fast to me in my truck, I don't have any desire to push my 5000 beast any faster than that.

 

Ask silverstreak or optikal about it. Id rather get sbc valved and a summit truck cam that works from idle to 3500 rpms. the valves are 10 bucks each and the cam is 100. now thats 220 bucks that will put out more power than a chip.

 

Well My Friend Got His Put On Its The Venom Chip From Summit And Actually It Aint That Bad Very Responsive Throttle And You Tell It Has A Little More Umph . Im Gonna Get One For My B-day From My Dad And See How It Is In My Truck His Is A 88 Efi I6

 

what about the 460 rocker arms they are 1.73 ratio. and no guids or machine work. cheap too boot!

 

well as for some answers to this reponse like i was saying before chips on stock motors except diesels are stupid and any1 reccomending on running a efi engine at 160 degrees shouldn't be selling them. The only thing aftermarket chips can do for a stock engine is change your fuel maps a little (usually richen it up a little and you gain a very small bit of power). If you want more power, increase your timing to the point right before the engine pings (detonates).

Make sure you don't rely on ford dummy gauges plz. I gurantee your truck isn't running at as low temp as your gauge says. My truck also never go's up much but, i know that it get's pretty warm. I'd install a aftermarket gauage or get a thermomete to check it after a heavy run or such if i were you.

As for a cam increasing rpm's, you get a cam designed for a certain rpm and power goal. say you have an ultimate goal of 200hp out of your 300 you tell the cam manufacturer that and tell them that you want it designed to run from idle to 3500 rpms. You will end up with more power out of an aftermarket cam than a stock 1.

As for a 2-3hp gain from chevy rockers the 2-3 hp was only at a top end. Your not counting the hp gains through the lower rpms, i remeber a overall max gain of around 12-13 hp....... Which is dang good and i'm sure noticable. The chip manufacturers will show a gain of like 13 hp but, not show you dyno charts and won't tell you what the chips actually change either.

As for the last comment on running a 300-6 at 110-120mph, g/l i don't see that happening. You must have some realy high gears to run 105mph as it is. Just make sure your tires are properly inflated and rated for high speeds before you go 120 mph. Stock trucks are very unstable at high speeds from factory. As for a speed limiter delete i'm sure most of the chips will give you the option to remove or move the top speed limiter higher. Most chips will even let you rev higher which also isn't a good idea. Whatever you decide though g/l it sounds like you are going to need it........

 

HAHA thanks for the motivation.

As for my top speed driving, ive been very steadily learning how well my truck moves at speeds and so forth. Ive got 3.55 gears, and 31X10.5 AT (not off road, not street, kinda like a spork, very useless) tires, the m5od tranny, and a 300 with alot of intake and exhaust work, as well as an electric fan. If i push it, I hit 30 in first, 50 in second, 75 in third, and my stock top speed in 4th. I hang out with the local ricers, and pull the ballsy ones out of the mud after they go off roading everynow and then. Through the late night cruises, Ive taken our main racing road (behind our airport, just paved, no traffic, long slow corneres that are just a little sharper than interstate corners) at 85-90/95 no prob, no under or oversteer. Very impressed with the 4x4 flareside suspension.

As for the rockers, they seem like they maybe a very good investment then, what kind exactly and where can they be purchased at, and whats involved in the installation.

As for cam, Im guessing to increase power with a cam its just a higher lift cam, with maybe a slightly higher duration?

As for staying cool, how would an aftermarket water temp sender be installed while retaining the stock one for the computer.

Finally, I may look into purchasing the venom chip for the truck, depending on where I go with my second car (a real race car, a 67 VW bug) because if it looks like I will focus on the car more, then the trucks mods will stop with the above stuff and maybe MSD, but if the truck seams to be my main money pit, then a megasquirt ECU will be going in, which in itself only cost about 350$ and is a fully tunable standalone ECU.

My goal is about 200-220 HP, and I think i can do it hehe, if I cant, then the truck is going to be bottle fed up to it. muahaha
