|sqzbox||With a nice body like that, I think a rebuild to factory spec's, a set of headers,intake carb, and a nice dialed in ignition, you'd be a happy camper and, it would be reliable and fun to drive. The cubic in. alone will take care of the grunt, for not a lot of money.|

|ericnova72||I'll really be the devil's advocate, build a 350 DX deisel block based stroker if you want real power . One of the available combinations comes out to 442 cubes also, a nice coincidence You'll never have to worry about strength.|

|joe_padavano||Sorry guys, but the 455 Olds only weighs about 40-50 lbs more than the 350. Why WOULDN'T you want an extra 105 cu in?|

|2ndchanceauto||i have never had a big block in any of the cars i have ever built. Its time, since i don't feel the need to got over 125 mph i am really looking for the low end torque of a big block. I will have to say that in my area the cutlass gets ALOT of attention everyone has a chevelle or camaro ect.. the gto's, cutlass's, and gtx's done right get alot of recognition at shows. I guess i should clearify i don't want to build a 4-4-2 clone just want the parts i like and put in my car. i don't care about resale, this car will never be sold by me.that rocket would look awsome in a street rod though something different than an ls1|

To play the devil's advocate for a minute- there's plenty of potential in the 350. Put some #5 heads fitted w/the 2" x 1.625" valves w/some porting of the bowl, etc.
A cam and the head work along w/a good high rise intake and a single 4-bbl. carb (think Q-jet) and a good exhaust system will put you right where you want to be. Obviously the rear gears and torque converter has to be optimized as well.
I love it when I read how the Olds 350 is such an awesome 'torque monster', pulls like a freight train, etc. The fact of the matter is, the bore and stroke is more oversquare than a Chevy 350! The 350 needs to REV, not poke around at low RPM!
The 330 Olds crank was steel, if you can find one. You will want to get better rods if you can swing it, otherwise ARP hardware and resized at a minimum.
Be aware that not just the 403 main webs were windowed. '77-up 350's (except the diesel) were, too.
There is plenty more to it than just this- I do not pretend to be an expert on the Olds. But I have built a 455 for a V6-equipped Cutlass (went easy 13's w/a 2.73 peg leg rear end, engine basically stock except a mild cam, fresh pistons, etc. from a wagon), and built another 350 for a buddy and refreshing a third 350 Olds top end. The results were all good.

Standard gearing in most 70-72 Cutlass was 2.56, thats a big reason that theyre kinda doggy in stock form. Even if you build the engine and leave the converter and rear gears stock, youve missed the most important part of building a quicker car.
Before you waste your money on anything from Mondello, check the 'net for refrences. Mondello has a very poor customer service rating and is generally overpriced. Plenty of places you can get the same parts for less.
Unless youre trying to build a 10 sec race car, then Edelbrock or reworked factory heads with larger valves will be more than enough for a torque monster.
Build for low end torque and you'll be very happy.

My "gutlass cutlass" will cruise at 125 all day long... The Olds 350 is a MUCH better design than the SBC, only problem is parts availability
Properly done the 350 can do VERY well, put it needs more than just slapping on whatever parts were on sale that week. 500hp with modified factory heads is doable. You can do that with the 455 too, you'll just spend a little more in the long run, but the 455 will have more torque.
And depending on what you have and what you compare it to the Cutlass can do better than "chevelle type money." So many people underestimate the BOP's.
the 455 is not a bad engine at all, it's just not needed to go fast. What is needed is an intelligent build from the ground up.

The rocket 350 came in various "disguises". Out of the box, mine was a 195hp +/-. I put the 4 barrel on, I did the dual exhaust and I bought the headers. Not installed but that's another story. :-)
Bottom line is it's a dog. This may be why they were called gutless cutlass when I was younger. Tuned to the nines and running well mine tops out at about 110mph. My buddies warmed up 350 Monte Carlo shifts into 3rd at 110!!!
Like the old adage goes, there is no replacement for displacement. My 350 will be warmed up and ready to go back in or will find a new home. As pretty as these cars are, they will never bring Chevelle type money in the market so keeping it #'s matching is no big deal IMHO. Period correct is close enough to me. '72 is the year I got my license and if I could have afforded one of these then, it would have had the 455 or I would have dropped one it then too.

Keep the Olds 350, properly built its more than enough engine. Last one I did came in under $2500 for a pretty nice engine and it pulls like a train.

I have a '72 'S' that I'm doing the same swap in. I bought the drive train etc. from a '76 Delta 88. I already converted the bench to buckets and put in the console.
The engine has been torn apart and sent to the machine shop and for something that sat for 6+ years it looks good. The engine started before I bought it....a little gas in the carb, a strong battery and she fired right up. I paid $800.00 for engine, tranny (T400), rearend and rad. A strong price for sure but that was loaded onto my trailer.....seller pulled it and used his front end loader to lift it onto the trailer.....I just drove and handed over money. :-).
I haven't picked the parts yet so please keep me (us) posted as to what you go with. I'm leaning towards Mondello heads and intake but can't get any feedback on them from anyone who has actually used them in the last few years. Eddelbrock is always a good source so they may get the money in the end.
I have posted a few pic's of my ride on here "somewhere" but don't really know where they ended up. Mine is green with gold pearl and a white interior.
