Re: best injectors

I would add go bigger, most heads/cam motors need 30s. For a blower on a stock motor I would look at at least 36s just because the mod bug will keep bitting and you will need bigger later.

Re: best injectors

Yeah at least a 36. Probably a 42lb if you are going to run much boost. I am going for 8psi with a 355 and AFR heads...it's gonna max my 36's out

Re: best injectors

Yep, good copper plugs starting a step colder with tighter gap.

As for the injectors, there are several type. Ball, disc, and pintle. The Ford (Bosch) style are pintle. Their biggest advantage is the ability to operate under higher pressures, which may be necessary if you're using an FMU. I don't like FMU's The pintle injectors are popular and work well. I've heard many bad stories about Accel pintle injectors so I would be wary of them. I prefer the disc type. Disc injectors have much lower response times and won't foul up. My Lucas injectors work fabulously and by buying from Acceleronics I support this site and deal with an excellent company I would also recommend going bigger. It's always good to have head room. Most injectors under 50 lb/hr, when tuned correctly via the PCM, idle and drive just as well as anything else. Bigger than that and I think it's best to go low impedence. At least go for the 36'ers IMO.

Re: best injectors

Id go with 36's. maybe even 42's. Its easier to have too much than not enough. Besides this way you can run a smaller pulley if you want with jsut a tune.

I need to get 30's or 36's and couldnt deicde what to get for my HC set up.

I was thinking for 36's pintle type, but I dont know enough to know what is more reliable pintle ball or disc. Although for what its worth, I have heard bad things about Accels but the Fords(Bosch) I have never heard a single bad thing about.

Re: best injectors

Maybe he has something here:

Spark Plug Types and Designs:

There are hundreds of different spark plug types designed for different engines as well as specific applications. The two main ones we use in racing are the standard tip and extended tip. It is my opinion that any time you can use the extended tip, do it! The longer tip gets the spark kernel started further into the center of the bore for a more complete combustion process. This is also achieved with the better aftermarket cylinder heads on many available engine applications. The newer heads position the spark plug location closer to a more optimum location.

But, there are also specially designed spark plugs that are supposed to increase the spark kernel size. You see, the larger the spark kernel that is generated by the spark jumping the electrode gap, the more complete burn, the better power and efficiency and the smoother the car will run for longer periods of time. These specially designed plugs will have multiple angles that allow the spark to find the easiest path as well as getting the spark kernel out from under the ground electrode which can quench the kernel size limiting it's size and expansive growth.

Of these plugs, there are those that work, those that are hype, and those that are a great idea but they are manufactured by companies whose only purpose is profit instead of quality. Use common sense and don't believe all the hype that a marketing company bombards you with.

One thing to be wary of is plug material. Of the plugs I've tested, the fine-wire gold plugs have made the best power, but at the price of a short life, which requires short replacement intervals. The Platinum plugs are only good for longevity, though most imports run better with a platinum plug. This has to do with the material of the cylinder head and engine block and the plugs ability to properly ground.

People always ask my plug recommendations. I must say that I like the NGK V-Power Plugs, the Champion Premium Fine-Wire Gold plugs, and the Nippondenso U-Groove plugs for domestics. In the Imports, the Bosch or NGK Platinum plugs usually work best. I have been testing the AC RapidFire plugs currently and I must say I am impressed by the results. Plugs that are useless to me are the Split-Fire plugs (poor materials -- actually an Autolite plug with the "V" tip), and of course the Autolite plug itself. I have seen the most failures and poor performance out of these plugs. This is not a bash session, so those of you that love your Split-Fires or Autolites, I'll wait for you at the finish line

Re: best injectors

I didn't even notice you're from Cedar Rapids. You talk with all the f-body guys out there? There's a few of them in the area that I'm sure could help you out. I also drive out that way every now and then. You're only an hour and 45 from me... I've even got a buddy that works there all week.

If you need something done like PCM work, let me know! My wideband equipment is currently out on loan to one of the Chicago guys though
