Look like I may have to replace the engine in my 57 4 door hardtop.
I can get a crate 350- 260 HP from JEGGs for $1500 -no shipping. But I like the loping cam sound of one with a slightly hot cam. Dependability is my priority as all I do is cruse with the occasional long trip. I have a 700R4 installed.
Suggestions?

Several local guys have bought engines comparable to that and then done a cam swap to obtain the sound they were after.

But Terry, wouldn't that void the warrantee? I don't know ,just playing the devil's advocate. Can't you get the cam you want from Jeg's already put in it and still have warrantee? Just saying....

4 bolt main L-31 Vortec

Just a suggestion. From Summit or Scoggin Dickey in Lubbock. $2060.

http://www.summitracing.com/parts/nal-12530283?seid=srese1&gclid=CKHhuYr57bcCFWdp7AodjzEAgw

from description:
power-producing Vortec cylinder heads with 1.94 in. intake valves and 1.50 in. exhausts, and 64cc combustion chambers that yield a gas-pump friendly 9.4:1 compression ratio. This combination is paired up with a roller cam that has 0.414 in. of intake lift and 0.428 in. for the exhausts.

Good luck on your search. Is your old engine worth rebuilding?

I've contacted a local machine shop and asked how much to go through a set of heads. After he shot some prices at me ,he said earnestly,I hate to turn away business, but, it is much cheaper to buy the heads already done from Jegs or Summit. Then sell your old ones and you'll be money ahead. So, I'm assuming(oh-oh theres that word again!)that the same holds true for the engine. I have checked out the heads and its true for the heads.

If you change the cam I'm sure it will void the warrenty. Just pick out one a little hotter....:tu

I looked at that Summit engine -Big Block. the price is right.
Will that roller cam give me the sound I'm looking for?
My engine is a 93 Roadmaster from a junkyard. It has good compression and the spark plugs looked fine when I removed them. My intent was to use it and the 700R4 that came with it as a sort of template to get my side mounts and everything else in and lined up plus the serpentine setup.
I don't have the time or energy to overhaul this one.

This one is the same as the 260hp but has the old L82 cam in it. It has a slight exhaust lope.

Changeout.

Will that roller cam give me the sound I'm looking for?
No, the cam will have to be changed out, for some rumpity rump.

I don't think you can beat Otis' suggestion relative to the $1500/260hp engine. $400 more, it's put together already, and has a warranty. And seems to have the cam specs you want.

My notion would be to turn to Pace Chevrolet for that engine, then call Iskenderian Cams in California and order a cam just one step above an RV cam, then pick up a set of Harland Sharp roller Rockers and you are go to go
This gives you a lope, good Rev's with the roller rockers and cam and it does not kill your gas mileage. Sorry about the 700 r, I could have sold you a remanufactured Muncie with a new gearset
Been there and done that

BUT, muncie's don't have overdirve!

no one wants a 1 to1 final gear out the trans!
OD IS the way to go, so that leaves out your muncie!

I may get the GM 10067353-K that Fox recommended.
My engine has not been overhauled.

This is the engine I would go with. Its a Vortec 350 replacement designed for the truck with over 8600 gvrw, so it has 4 bolt mains. The Vortec 350 was rated at 255sae net [email protected]/330 lb/[email protected], but to compare to the other engines in this thread, it really puts out around 310320hp. I have over 400,000 kms on mine. With hundreds of 1/4 mile drag passes and thousands of 0-60 street runs in my pickup truck.
These engines come with Vortec heads and the 191º/196º 0.412"/0.412" lift with a 111ºLSA. These heads are the highest flowing heads installed by GM on a production GEN 1 engine....EVER! Better than the oft lauded "fuelie" heads that make 375hp on the 64-65 L84 fuelie and 365hp 1964-65 L76 327 engines. These heads are based off of more modern tech than the other heads in this thread for better power and better fuel economy.

Whatever you do don't get the 330hp 350HO, as this engine is simply a Vortec 350 with its roller cam taken out and a flat tappet cam installed, then hundreds added onto the price.
