Alternative to turbo charging

I am a kid who just bought a 62 with a 305 and my old mechanic boss told me that maybe stiffening up the valve springs and a twin turbo setup and it could breath and nobody would touch it ,but it is a classic and twin turbos would look cool but not go with the times so are there any alternatives ???? But get the same result

What model '62 Olds? You might consider a larger displacement motor from that era if it was available in your model. As far as hotrodding, you would be far ahead dropping a 350 in, it looks the same, and easy to make more power. Save the 305 in case you need to return it to numbers matching.

"Does not go with the times"? Not exactly true,you might want to read about this Hot Rodding pioneer:The Best Hot Rodder in the World: Ak Miller - Hot Rod Magazine Back in the early 70's I was retail manager at the place in the picture below,we were selling Ak Miller turbo kits in single and dual configurations for mostly big and small block Chevys and Fords and the Pinto 2000cc.They were a simple design and most could be installed in less than 8 hours.Here's a link to an early kit with pictures. http://67-72chevytrucks.com/vboard/s...d.php?t=491223 The first American production cars with Turbos were the 1962 Olds 215 and the Corvair Turbo introduced a month later.As a side benefit these early turbo kits not only upped horsepower but usually 4-6 more MPG.

I think by old 62, he means an old 62 gmc with the 305 60* v6. Afa period correct goes, I think OP is looking at a roots style blower for this build. In the end, I dont think its worth it though. Theres only so much boost this thing is going to take and its already a pretty old engine to begin with. Not to mention it's aftermarket support is absolutely non existent. Obviously a sbc is the first choice, and its going to require a new tranny as well. Another option that would cool is a larger gmc v6. The 305 was the smallest, and I believe they get as big as 478 cubes, but are like looking for hens teeth. If I wasn't running an olds motor in my 65 c-10, my next choice would have been a w-series 348 or 409, followed closely by a buick nailhead.

M&M was the retail division of United Speed Wholesalers aka USW and they supplied Auto Parts stores all over Central and Northern California and Southern Oregon there were no other retail outlets, this one was located at 2660 Albatross Way in Sacramento about a mile from Toggnotti's which once was a Safeway store,In the 70's one of our early regulars to the machine shop was the late Gary Ormsby and Lee Beard,we also did a lot of engine building for the sprint cars that ran at the old West Capital Raceway.The Spiegel Bros worked the phones at USW and ran this Gasser "back in the day" (see Pics below) after the car was retired the engine was on display in the front of M&M's showroom. USW & M&M were founded and owned by the late Al Morris.Here is a Google link to the location:http://www.mapquest.com/maps?address...&zipcode=95815

if it is a 62 gmc truck with a 305 v6 and not just an 62 (pick car model) with a newer 305v8
if it is a gmc truck the trucks would have a PONTIAC v8..
and in this case more power is easy. instead of a period correct pontaic v8. go straight for the 455 Pontiac or dare I say it 500cid catty..
remember kid, you need to be able to feed it. big cid engine use allot of fuel.. so do turbo'd engines when you hammer them..
going with the Idea that this is a 62 gmc truck.. you could drop in a Pontiac unloved 326v8 drop a turbo on it , or a procharger that's closer to period correct than a turbo.. yes both were used back then.. the Paxton was what the procharger is based off of. and there were more Paxton s/c on the street than any turbo's back then..
build the 326 correctly and it'll make enough power to scare you.. it being passed by, because everyone goes for the 400/389/421/455 is a bonus as that = cheap to "buy in" same with the Pontiac 350.
what you think todays chevy truck 5.3ltr is yup a 326.. and frankly if you are hellbent on a turbo'd engine. that's the one I'd look into as it's been done a bazillon times and 5.3ltr engines are a dime a dozen, but you'll need to leave the period correctness "look" at the door.. and after having a 301 turbo and installing a 400 and try'n to get the turbo to work with those extra cubes and then re engineering 2 mopar turbo's for it to blow through.. you'll be 100x better off with an efi engine. I finally got that t/a to run mid10's with that pontiac400 dual turbo blowthrough carb set up.. but it was a lot of try this, then try that, for about 2 years.. car was 4134 lb's

Its not a "Classic". It is just old. Why should you care if it fits with the times or not?
Who cares. Its just a old motor in a old truck. Do what you want with it.
Cause nobody cares, nor should they. Least of all you. Its your truck mod it how you want.

It is 2013 not 1962. If you do a good job moding it, it will be "a cool old truck". Thats a bit different.

Even if you gold plate it, it still won't be a "Classic".

My god.

Supercharging it with say a Eaton MP 112 or MP122 blower might be fun too.
