David and Goliath-?

Hope this is not to boring but have phone calls and e-mails wanting to know how the 262 would run with a 308 engine.

We did the drag race test this morning.

1946-262 turboed engine 1954 -308 hornet

100,000 miles X 100,000 miles X

std.trans. 2.73 diff. Hydra. 3.07 diff

308 alum.head milled .040 323 iron.milled .040

Large 2-barrel rochester carb Holley 500 cfm 0.50 jets



Had to start from a roll at 30 MPH in low and stab-it.

the 262 jumped the 308 just a bit then the boost came in at about 2500 RPM and at 5000 RPM and a boost of 4 and 1/2 lbs made a shift to second then the 262 pulled ahead at the same time i had to let the foot-feed up so the corks could grab then started pulling away at 5000 and 4 and1/2 lbs of boost ,then shifted to third. The 262 was pulling strong at 80 mph and was at least 1 and 1/2 car lengths ahead of the 308 and pulling away.

We ran 3 runs and test were almost the same.

The turbo has some Lag and comes in at about 2500 RPM. A belt driven Supercharger would have jumped out ahead of the Turboed engine as they have no Boost-Lag.

A turbocharger works better with a Auto.Trans,as you can Stall the Converter and build up some boost before you launch it.

Now if i can stop playing around with this Fun-Machine and remove it to install on my 308 with Auto.Trans ?

I think that the 232-262-308 will be a dependable and powerfull eng.with no cam,valves,or porting Mods.and the boost down to 5-7 PSI

I hope that others will give the Supercharger or Turbocharger a try and if it does not perform it will Scare the heck down on them when they see it.

Happy Hudsoning to All. Rudy and the Locals.

...And the pictures!

This is really cool stuff!

I'm surprised at the ability to crank the ol Hudson steady at 5000RPM - what is the upper RPM range on a Hudson motor anyway?

I seam to recall Jack Clifford stating redline on the 308 to be 4800:eek: i don't recall seeing a number for 262 but the shorter throw would buy some extra rpm's before the crank snapped.

Rudy is running a 262, all reports on those engines is that they will scream compared to a 308. They don't have the 4800/5000 rpm ceiling of the stock 308. A good Hudson combination for rpms would probably be 308 block with 262 crank. You wouldn't think that 1/8" less stroke would make such a difference, but it evidently does.





Good Lord Rudy! If you had a lower geared rear end - you'd be lethal in the 1/4 mile! A good floor shifted OD tranny, some tighter springs in your pressure plate and a 3.58 rear end - you'd give Randy and Dany fits at the Hudson nationals in July. A driver and a butt whooper - can't beat that.



Excellent report! Hopefully I can get back on my project soon, this is definitely serious inspiration.



I kinda wish you'd have built a 262 as the final engine, not only could you confound the V8 guys - but us Hornet runners too. That would be neat.



I'm all exited now. Particularly since its like my own engine with few internal modifications.

Rudy, I hope this took place on a legitimate track!



and this wasn't a few older guys getting together for some early hudson drag racing!



hehe....

super651

Bill, cant do the 1/4 mile due to Smoking Corks (clutch that is)

If we ever get the 308 with 200R4 and a To-4 in the 46 then,we can get some 1/4 mile times.

Rambos,

The 262 Rpm comes on so quickly with Boost ,you have to watch the Tach. or no telling what would happen.(mabe an X-Ray of the Block would suddenly Appear )

We were on a Farm Road ( 2-LANE BLACK-TOP) and we were sure that a couple of farmers saw us. Can you just hear him on the phone to the local Law,Hey there is 2-old Hudsons with 2-Old-Men out here Drag Racing ? plus a Chase Truck to pick up the lost parts? And no, Ihave not had a Drink Yet but ,after seeing this I need one and a strong one at that.

Thanks to ALL for the intrest. Rudy and the local old men in there old Hudsons. It was a Lot of fun,and sometimes we need that.

OMG, if I was anywhere close, I would so break my car messing around like this.



Hudsondad never wants to race, or drive his, so I'm kinda solo on the opportunity. He is doing the 4 barrel and header install, so he'll probably be much faster than I would want to tackle....



I think we should all look for a back road of smooth 2 lane and do some video clips. who in their right mind is ever gonna arrest anyone for this, or believe it?

Hard to follow as I can't figure what car has what from the description. Still sounds like fun and I might want to run that turbo car after I get my 308 done I've got my trans buddy looking at options to get rid of that wet clutch and put something more modern and substantial. I am surprised more people haven't upgraded out of those wet clutches by now.

super651

464, Got mixed up a bit.

The 1946 has a 262 with the Turbo and STD trans. 2.73 diff and a Well worn 9 inch clutch.

The 1954 has a 308 with large 2-barrel carb and Hydra.trans.with a 307 diff. Both have well over 100,000 miles and lots of blow-by.

Hope this helps. Thanks Rudy

OK Rudy now I got it. You are quite brave to put a Turbo on a motor with over 100,000. My 308 just let go with a broken piston with nothing but cold air coming in from the 54 scoop across the Twin H. I have started quite a thread on rebuilding it, jump in take a look and throw your ideas in.

Mark, You are on to it. Jack C. did run a 308-262 combo for a while,and maby Randy M. can shed some info on that engine,as he and Jack were racing a lot back then. ( help us out randy,how did that combo work??

If the 262 crank holds out a while and when we do the 308 transplant we will diss.the engine and have the 262 crank Sonaflexed and use it in a Combo 308-262. And on that Supercharger install,when it is done you will be able to jump a Turbo powered Hudson in the Low pulley position. There is a Studebaker Hawk out here that Runs Strong with that set-up and he is running Factory Blow through 2-barrel carb. I think you will be pleased with that set-up.

Now I have to SLOW this old body down a bit and get down to Atlanta Ga to help #-1-son run his 10 second 401 Powered AMX ,what a wheel stander.

Thanks to all Rudy.

( by the way,found out last night that the LAW-MANS name that patrols those farm roads has a last name of HUDSON,now that would have been wild for the farmer to have made that call, Mr Hudson,there is 2-old Hudsons with 2-old men drag racing over here. I think the Lawman would have took that as a joke and hung-up on him )

I never calculated the displacement on that combination - but look how handy this is.



3.8125 bore x 4.375 stroke = 299.59 CID



308 block with 262 crank.



I think most of us have considered going the opposite way, 262 block with 308 crank.



It might be advantageous to give up 8 cubic inches to gain maybe 1500/2000 rpms. If a person could find some 8.200" long rods, you could use stock 308 pistons or custom pistons designed on standard 308 dimensions. The improvement in rod ratio might close the torque gap between the 300 and 308 displacements.



The rods would be the high dollar pieces.



Interesting proposition. I'm paying more attention to 262's, they may be unsung heros in the Hudson lineup.



On the supercharger, I hope you are right Rudy - I have alot of confidence in your opinion. Particularly since you've been there and done that already with the very supercharger I have. I'm getting more comfortable with how the 4 barrel works with the 308 and the state of tune I seem to be in, that is absolutely essential going into the addition of the blower. I'm getting there!

Somewhere, packed away, I have a whole list of bore x stroke combinations for 262 and 308. Also in that list are combinations using parts from one engine into another, ie, 262 crank into a 308 block. It came from a letter a fellow in Washington state wrote me 30 years ago.



One thing I do remember, it was possible to bring a 308 up to around 350 CID.



I've got a place to live here in Memphis - will look for that bunch of papers and post what I find when I start unpacking in about a week or so. Should be in around the 27th, hopefully.

Wasn't that the same guy you posted about some time ago, that kept changing engine combinations due to rules being made to exclude him based on cubic inches? He kept swapping parts until he came in at or under the rules - and still beat 'em!



I like that story.
