I HAVE A 1984 HURST/OLDS THAT IS BONE STOCK. I'M WORKING ON A PARTS LIST FOR A REBUILD. THE THING IS I WANT TO PUT A SUPERCHARGER ON IT. BUT I DON'T KNOW IF THE ENGINE CAN HANDLE IT. WHAT I NEED TO KNOW IS IF IT WILL. AND WHICH ONE IS GOING TO WORK IF IT WILL HANDLE IT. I DON'T WANT A LOT OF POWER JUST SOMETHING TO GIVE IT THAT LITTLE EXTRA UUMMMPH. AND TO HELP SET IT APART A LITTLE AND MAKE IT STAND OUT FROM THE REST. ANYONE WHO COULD HELP, IT WOULD BE MUCH APPRECIATED. ANY HELP AT ALL, EVEN IF YOU DIRECT ME TO SOME ONE ELSE! THANKS!  

First things first, turn off your caps lock. Tends to irritate people.  Second, no your motor will not handle a supercharger for any length of time.  It should have an olds 307 in it, and they were one of the most gutless motors olds ever put out.  Save your money for a different motor.

see if you cant find some quality parts if it is a 307, if not, build a 350 (or even a stroked 305). again, quality parts and then slap on your supercharger.

Good luck.  Pro-Charger makes a universal supercharger kit that bolts to the older style GM A/C brackets.

A decent 403 Olds motor should scoot pretty well without the expense and complexity of a supercharger.

Here's good info on building the 307 Olds from those who have actually done it.

Dyers builds a 6-71 blower kit for the 307 Olds:

Not cheap, but then you wouldn't see one at every show.  A towering blower set-up would definitely "HELP SET IT APART A LITTLE AND MAKE IT STAND OUT FROM THE REST."

Nearly any low compression engine in reasonable shape will live under 5-7 psi boost if detonation is avoided (use a boost-timing retard, water injection, and don't run lean mixtures) and RPM is kept within reason.  See BDS's engine recommendations: http://www.blowerdriveservice.com/recommend.php

The 307 has windowed main webs, so the maximum safe torque potential is less than an earlier Olds small block.

You might consider archiving the original 307, just in case H/Os twenty years from now begin to bring as much $$$ as some earlier musclecars now do.

No matter what you do with what engine, reinforce the lower end.  I think that there are better choices for you, and even though the 307 might be desireable to turbo from a rarity standpoint, it isn't going to take the punishment as well as a 350, or a 403, or 455.  Stud the mains at least to keep main creep at a minimum, and keep the boost fairly low.  If you are doing a rebuild you can control some of the preignition issues with compression ratio.  From the standpoint of a classic, you WOULD be better served to save your 307 as a future resto, and to launch into an engine that is both more stout, and not original to the car.  If you are looking for the best blocks to use, most all the Olds blocks pre 1973 have high nickle content and would be better candidates.  350s are still fairly easy to find - 455s aren't as easy or cheap.  Best two years for the 350s are said to be 1968 and 1969.  Let us know what you end up with - Bowser.  

I have a 307 Olds in my 85 delta 88, its got 178,000 miles on it and never had the valve covers off it.  They will last a long time if they are taken care of.  That being said, they are not performance motors.  From what I've read, you shouldn't even try (cant remember exactly where I read that, but try 442.com).  Check out the supercharger article in CC from I think october (might not be, but its recent).  You'll probably need forged pistons.  If you can find a 455, get it, put some aluminum heads on it, and it'll weigh as much as the small block.  Otherwise a good 350 will do wonders (I have one with big block heads and other performance goodies and its fun. . .no blower though. . .hmmmmmm). 

If for whatever reason you decide not to keep the 307, I might be interested in it. Depending where you live, we could maybe work out a swap. Just got a 455, condition unknown(havn't checked it out yet)    

Call Mondello (805) 237-8808.  They can help.  My experience with supercharged Oldsmobiles comes secondhand, but here it is anyway.  A friend attempted to supercharge  a 425.  Mondello finally located a blower intake for him.  After a long search, he laid out around $800.  They also found a small block intake at close to the same price.   After hooking up the intake and blower,  he discovered  he would have to spend another atrocious amount of cash having his balancer machined to accept big block chevy pullys (which is what you want if you plan on trading around ratios for maximum power and what not, 'cause it sounds like you don't know many blown olds guys either).  He ended up selling the set-up for money's sake.  Take into account that this was a big block, and a few years ago when there wasn't even a victor intake for the 350.  You've been given a source for a 6-71 307 kit in a previous response, and that might work out allright.  Personally, I would steer clear of the 307 and the 403 because of their windowed main web, although it would be sweet to see a blown 307.  Mondello also has a main girdle kit that wold really help that 307 out, but it aint cheap either.  Otherwise, unless there have been vast improvements in the availibility of supercharged Olds parts, I would consider turbocharging, or just full tilt all throttle power.  Whatever you do, keep it rocket powered!

You are right on the Mondello Girdle and it would work.  It requires that the block be machined and modified to accept it however, and as you say, the cost of the unit alone isn't cheap.  Machine work at a minimum would be main studs, and oversized studs put in the oil pan holes to hold in the unit.  I believe a special oil pan, and oil pump pick up is also required as part of the modification.  If he wants that car to just go fast, the 425 is an awsome oversquared motor with huge potential.  Personally, I would pick it over a 455. I have been trying to score just a rebuildable shortblock but people who have them aren't giving them away.  Some guy on Ebay has an ugly one out of a '66 Toronado (if it really what he says, it's a cream of the crop).  I would love it, but without a rebuildable guarantee, or at least a right of refusal I am not going to plunk down $650.00 on a whim.  I have a guy down in Vancouver at a vintage pick a part looking for a rebuildable and he will guarantee the block.  He ain't cheap, but I won't be gambling away money either.  If it comes to the 307 or nothing, yea keep it Olds, but he should do at least the bottom end mods or it's just going to fly to pieces.

At least that's my two bits - Bowser
