Has anyone here tried a blower without going the 5.0 Fuel Injection route? If so how did it run? Would you do it again?------------------

Jas I have thought about doing this for an eternity.. I was thinking of going with a 174 powercharger from holley. It a root-style blower where the carb sits above the blower and sucks air through it rather than push it through so you don't have to worry about modding the carb. All in all it looks like a sweet setup. I was skeptical for a long time about the water neck because it looked like there would be no room for it to route to the radiator. I eventually found a person with this in his car and had him send me a pic.. he mentioned to me that you need to get a special radiator hose to solve the problem. Here's a link to the blower..http://www.holley.com/HiOctn/ProdLine/Products/AMS/SC/SCK/77-174_FSBP.html By the way, check out the PSI this thing can push, the 302 from 7-20 and a 289 from 11-24!!

Nos thanks I'll check the archives.Blown289 - Where did you get your equipment from? I'm concerned especially about the blower box around the carb and the pulleys and hoses. What type of PSI. Have you ever been on the dyno? rwhp? torque? mvierow - I've actually seen that one but I'm concerned about hood clearance more than anything else. In CA I'll get busted for sure with that setup. I have the Holley Projection TPI system now. I am also in the process of getting a 342ci roller cam stroker built for my car. Actually it is done, I'm just waiting for delivery. I am planning for down the road because this is a motor to just fill the gap until I can get more power. This block will be able to handle a blower so I was thinking to drop the compression and install a blower as the funds become available. I was actually thinking more along the lines of a Paxton or Vortech. I would probably be happy with around 12 pounds of boost.

jaz contact paxton as they still make kits for early mustangs with carbs. as far as 12 psi boost that might be too much for the stock set up unless you have dropped the compression down to about 8:1. the basic set up on the paxton pumps about 6 psi boost. i think you will find that quite satisfactory on your current motor. when you build the new one and want the 12 psi remember to lower the compression.

Richard - My current setup that's going in my car in a few weeks in 10.5:1. No way I'll be putting anything on that. I would swap out the pistons before anything else. The rest of the motor should be able to handle up to 12 pounds of boost. I have spoken to Paxton but I was looking for other options as well. I do like the roots type of blower but it would need to fit under the hood for me to use it. Basically it is illegal to use in CA so if it doesn't fit under the hood the cops almost have no choice but to ticket me. I'm not really sure what I want to do but I know down the road I will either turbo or supercharge the car. I was thinking of swapping to late model 5 liter electronics, manifolds and injection before beginning. I am starting to think that might be the best way. I have so much money invested in the car that sometimes I just think that if I could get back about 60% of my investment be selling it that I'd like to start from scratch rather than tear this one apart again.

You are in luck, its illegal to use in California on a pollution controlled motor vehicle, meaning '74+ (look at all the C**** guys running 350s with Weiands). The Paxton isnt emissions certified either. If it applied to all years you could never use a Holley 4150 or any performance carb on a car as they have the same disclaimer :>). Same goes for a lot of cams and intakes too. ------------------

I thought that we weren't required to smog but that we still couldn't put stuff like a roots blower on the car. I know my car isn't technically smog legal now but nothing jumps out at you like a blower through the hood would. I think that set up wouldn't even fit under a cowl hood. I must admit though that I like the stealth of a turbo car. No blower whine and no external cues and with my little 289 badges on the side it's a perfect sleeper. Well maybe the exhaust rumble is a clue but the Chevy guys think that Fords sound good but are slow. I live for changing those opinions.

Technically, you still can't do it, but I don't think you would have a problem with the local revenuers, unless you get caught for something else, like speeding, and he has a donut up his (censored)
The revenuers have got their hands full with the ricers and late model boys anyway Course, should you put something like a 14-71 on top of it, and a scoop higher than your roof, well... then you might get into trouble  ------------------

Jas, the roots blower won't fit with a stock hood, but will with a 2" cowl like those from Meier.. Thats if you use a low height air filter and no carb spacer.

I have a GT350 hood now. I was thinking of switching to the cowl hood now. From what I understand it can even be made out of Carbon Fiber if you want to pay more. I want to run a few more high speed events (Silver State Classic) and the scoop facing into the wind isn't working. It looked like a balloon at over 150.I guess this leads me to the next question if I can get this type of blower to fit. What are the advantages and disadvantages of each forced induction set-up; Roots, Centrifugal, Turbo? quote:
