I have been thinking hard about an EFI system for the old camaro just so that it is will be a bit more friendly, never thought i'd say that lol. When i built it i didn't mind hard starts and adjusting things from day to day. Anyways

I was thinking about the Accel system, seems pretty complete and i think it would be capable of running my little 468 quite well.

I would like to reuse as much as possible so i don't have to start from scratch but that is looking like only the fuel pump (A1000 and return already plumbed). If i keep my MSD it doesn't seem i will be able to run sequential.

What about prices on the different options? just ball park

Im also open for other opinions, i did look at the fast but it is pretty high dollar, is it that much better?

The combo is 468, 11.58:1
Victor Jr, also have a Dart single plane i could use
Afr 305 cc intake heads
Cam SFT 300/310 264/275@.050 630/650 lift on a 111 lsa installed at 108
4800 stall speed
3.73s and 28" Hoosier QTP's

Thanks

There is a lot of information in the post link below. Long story short I sell multiple EFI systems. You simply cannot beat the Accel Thruster deal. The FAST is god stuff, I run it on a few projects. But I do not seeing it as being "better". In fact truth be known I am enjoying the plug and play aspect of the Accel, and I really like the dash board. Not to mention the fact we have some really good deals on the thruster right now.

I would definitely consider the FAST or Accel Thruster Frank mentioned above, and I'm pretty sure he'll have great pricing. I would not recommend the standard Accel Gen VII, it's quite difficult to tune in my opinion (although runs great if tuned correctly) and would not be a recommendation I would make for someones first EFI conversion.

Listen to Frank.

What's a complete BBC thruster with WB02 retail for?

[ProdigyCustoms]

Our complete Thruster package including the Dual Sync distributor, 6 ignition box, coil, intake, injectors, T body, WBO2, harnesses, ECM, sensor kit, Fuel Pump, bla, bla, bla is a little north of $3500 depending on injector size and harness options like A/C control, Electric Fan Control, Power adders, etc.

That thread is what swayed me to the Accel, but just wasn't sure since that 468 is much milder then my. It is likly that engine will be past its peak hp around my stall speed is what made me wonder.

How hard would my combo be to tune with the Accel, or any other for combo for that matter.

How about the price without the fuel pump and ignition box? if my Mallory 685 will be compatible that is. But i do have the pump and regulator taken care of

Thanks

The advanced tuning capabilities of the Accel is perfect for these more wild motors. As for how hard to tune, you input all the information and she will run. How hard to tune is based on how well you comprehend instructions and understand the systems. What is very cool about the Accel, is if you get in trouble tuning wise, you are almost certain to find a expert to help.

As for pricing, I am not sure if your Mallory box will work. Being the Mallory is a digital box leads me to believe it will not only based on my previous experiences with other FI systems not accepting digital boxes. I will have to ask my Accel people. It is only $175 for the 6A box. As for the fuel pump, I just tried to order a kit fuel pump delete, and it has no value when excluded from the kit.

How about a 950 Commander MPFI?

I tried my hand at EFI for the first time and now I swear off carbs. The Holley is basic, but enough to still run 8's if need be (not on my car!)

Cost appears to be less than the Accel offering although I'm not aware of what a Thruster is.

Popular Hot Rodding did a piece on a 496 with AFR heads...made ~700 chp and idled like a street car...very streetable with the Holley system. I was sold.

There was another article that detailed beehive valvesprings that got them over the numbers with no valve float.

The Holley Comamnder Efi is cheaper and easy to work with.And now you can buy it with a AFR for tuning.

I just did a holley EFI on a 74 pantera 408 stroker 351C MADE 450HP ON PUMP GAS WITH 36lb injectors.
Here are some pics.I bought the holley universal kit from summit for $1049.00.

The ACCEL DFI is a little more involved and the Fast EFI is easy but costs more.
I made on my 540 nova procharged at 14psi and a 500shot of single stage nitrous 1100hp with 680lb injectors. Ran 8.60 on pump gas street driven on the holley efi commander.
They will all do the job.:hurray

As for cost, our friend yellow68 is making somewhere near 650 HP to run the numbers he is running, meaning he will need a 50LB kit. The Holley Wide Band 50LB kit part number 92407211 is $3454.99, add a HLY 890-160 distributor for $387,39 and a 6 box and coil from MSD, Malloy, Accel for $220? and you are a tick north of $4000. The Holley is a good systems and we sell it also.

[L48M20]

Prodigy: Are you saying the Thruster is cheaper with the same features? He mentioned he already had the MSD (assume coil too) and one doesn't have to go with the whole hog ~$400 Holley distro...HEI works too. But anyway...

The original poster is looking at easier starting, etc...exactly the reason why I tossed the carb off the car as well. That and the constantly varying idle speeds, fouled plugs, etc. As long as he can tune it...anything will work!

I've never been happier with the car (owned for 21 years). Especially with the datalogger and all. Very slick.

[ProdigyCustoms]

The Thruster is less money equally configured. If you deduct the the box. distributor and coil from the Accel, it is less money. He asked about running sequential. He CANNOT do that with a MSD distributor, and the Holley does not run sequential at all. But with that said, sequential is not as much a advantage in NA applications as it is boosted or sprayed. So he does not NEED to run sequential, but may want to. I run everything sequential if I can.

[collingdale]

Holley runs batch fire injection ,so no matter what ditrubutor or type of motor you have it will work.The GNX turbo Buicks run sequential. And accel DFI is the way to go on them.
Here is an 87 Pontiac on the dyno with Accel DFI- 262 CID,that was making 650hp at the wheels on a mustang dyno 20psi. boost.Very common on buicks sequential fire, dynoed last week.
Its all about personal choice and your budget.

I've got a Mass-Flo system on my 302 (ford). I'm very happy with it. You can find out more about it here: http://www.mass-floefi.com/

Chris is also good to work with.

I'll be going this route again on my 69. Also works well with a centrifugal blower.

It really is plug and play and I got about 20 mpg in my roadster with it.

I looked in to that mass flow before and when i spoke to them, they said i was limited
to how far i can make tuning changes.For me it was not what i was looking for and the customer. Here is good article on it.
