152 & 196 cylinder head swap?

I have a 1961 s80 with a stock 152 engine. I also have a locked up 1978 196 engine on my shop floor. Guessing by the bearing material in the oil filter the 196 has spun a bearing. My 152 needs to be pulled out and freshened up. Can I use the 196 entire top end on the 152? I am hoping that by using the 196 top end that I would gain some power due to the larger valves and better flowing head. Has anyone done this? I am concerned about piston to valve clearance? Cooling system differences? Oiling system differences to the rocker levers? Thanks in advance for info!:icon_up:
 
That combo will not work.
The 196 being a 1978 is an ic (improved cooling) design. It will only fit a ic 196 or ic 392.
All 152/304 and 345 engines are a socalled non ic. The cooling passages in the head and block are different..

If the engine in your 61 is original, it will be a cotoured piston. That block needs a head designed for the contoured piston. Your best bet is to go through the 152 and use a larger carb. The 2 barrel weber is a common swap.
 
Thank you for the info. I have access to 345 heads... Is there any advantage to using a 345 cylinder head? If so what year of 345 would I be looking for? The 196 has a 2 barrel carb (looks like a rochester?) since the 152 has a 1 barrel carb what is the best way to adapt a 2 barrel too it?
 
The 345 is the same bore as the 152 so the chamber is properly sized. The 345 head has the larger intake ports like the 392 but the smaller valves. Should flow 10-15% better as is while still making better low speed performance.

First problem is 345 head will require a 196 intake manifold due to the large pattern ports.

Second problem is that the 345 I don't believe was ever made with a contoured piston so if you do decide to use one on your 152 you'll need to use the e style flat top piston..

You can use the 196 carb, just May need to jet it up a tad like from a #60 to a #63.
 
The 196 is locked up due to the previous owner allowing huge amounts of water to flow into it.
:dita: the middle fingers are to the previous owner!

ah oh. Its a big bad jake sighting on the IHPA forum. There goes the neighborhood.:prrr: threadjack over.

Oh damn it! Now I can't act like a newbie anymore??? Wtf! Lol:d
ok next question.... So my Dad's 1966 152 has a flat camshaft. Will the late 70's 196 engine's camshaft be a suitable replacement? Has anyone done this swap? Would the camshaft have anymore lift than his original? God knows the 152 needs all the help it can get!!! :icon_blaugh:
 
I'm not sure about that came swap either. But during a recent talk I had with Jeff up at IHPA, no aftermarket cams are readily available for these two 4 poppers. They normally take the stock cam out and send it off to have re-ground.
 
Will the 196 cam work in a 152?
Yes and no. Yes the lobes and other features are ok and will run.
The fuel pump mounted on the side of the 152 is actuated by a special lobe in the middle of the cam. On the 196 cam that lobe is not there so you'll have to install an electric pump.
 
Really appreciate all your help rk! I guess I will be pulling the cam out of my old 152 and sending it to oregon.... Ouch shipping is going to be expensive! I will keep all of the lifters in order and send them along with the cam. That is great that IH Parts America has reman camshafts.... However I do not use welded camshafts. In my line of work I have seen way to many of them fail.
 
If you're sending it IHPA it's not oregon but California... Either way you'll be good.. Jeff has a great regrinder that he uses on the 4 popper cams.
 
Actually my Dad lives in oregon (the cam in his 152 went bad) and I live in alaska (I am pulling out a 152 from my plow rig)... Just dreading the shipping charges..... And I don't want scoutboy74 to worry!! I am not sticking a fuel injected 350 into my plow rig! (like my other scouts :devil:) I am currently replacing most of the gaskets on the 304e that I drug home. That way at least half of the gaskets on it might not leak! :icon_lol:
 
Worry? Not me. If you was wantin' to heave big mud pies 20 feet into the air, the chitvy motor would be the ticket.:prrr:
 
Lol... I still find my self going onto scoutboy74's you tube page & watching that video "pie throwin" ... That was a good one! Just spent the last couple of days cleaning up the garage to get the plow Scout "tucker" and the 1970 800B "patch" into the garage. Its going to be tough to not "accidentally" :yikes: drop the TBI 5.7 into the plow rig since I already have a engine and a wiring harness that I built. But those parts are set aside to put into my 1970 fj40 landcruiser. I am anxious to fire the engine off. It has a big block TBI, pro topline cylinder heads (suppose to outflow vortec heads), hydraulic roller camshaft (biggest one I could fit and still keep it fuel injected) hypereutectic pistons (about 9.5 compression) and a GM goodwrench 4 bolt main 1 piece rear main seal block. I am estimating it should put out 375 hp and have a decent amount of torque.
Next I have to figure out how to build a 345 or 392 that will put out enough power that I can be happy with it!!!:idea:
