Some advice,

I own a 1965 convertible with a 300 hp 327 in northern Italy. The upgrades are VBP front and rear suspension mods (front springs, composite rear spring, shocks, etc. I am running 8 inch C3 wheels with 235/70-15 tires.
My engine is the stock 327, matching numbers block. The Vette runs perfectly, in the last 5 years of ownership have only changed the oil, starts right up, very smooth. It needs gaskets though, leaks is several places, less than 1/2 quart per year. Rather than opening up a 45+ year engine I was thinking of going for a new crate engine (also because finding a mechanic with small block experience is not easy then there would be the down time in ordering parts, etc.

I received an offer for a 400 hp crate engine, my question is that with this new set up I am afraid that it will become too much like a race car, I like fast but fast with control, will I need to reinforce the frame? The rear end is a 336. I do not want a race car bout would appreciate some extra ponies.

This is the quoite below, I am afraid that it is too much for the old girl as is .... comments?

If it bears the U.R.E. logo, it is a top quality racing machine.

WOR 2008-2009 Champion Comments on his URE Engine
“Racing through the toughest deserts on the planet in the 2009 SCORE Baja 1000 our URE equipped class 8 off-road race truck did not miss a beat. With on demand power and torque at any rpm we were able to propel our near 6000 pound race truck through any obstacle that stood in our way. With outstanding performance and customer support, I would certainly choose URE.”

your car will be fine with the added HP

kellsdad

In any drivetrain, the weakest link will be the first to go. I believe the weak link in your setup will be the tires, meaning the tires will break traction before you can break anything in your drivetrain. That's a good thing. If you start going to the drag strip and running racing tires, you might break something else. But for street use on street tires, the engine you are considering should not require strengthening of any other components.

Mossy66

I agree, that the car will be fine...I'm worried about your neck!

Kerrmudgeon

Should be no problem, providing the rest of the drive train is in good shape, like all the U-joints, transmission, rear end, wheel bearings etc. These things came with close to that horsepower from the factory. It'll depend on how much you beat on it, but you don't sound like that sort. Ask questions of other buyers from that company to ensured their reputation of a quality build. I can't imagine what the shipping $$ would be....

But, I gotta ask, if your happy with the current motor, why not just change a few gaskets, and throw some seal softener in it. (Leak seal added to oil). Or just the gaskets....it's not leaking very much really...

Peak HP and bags-o-torque from a dyno chart are impressive, but driveability in the real world is much more important. Watch out you don't end up with something that has bad street manners.

claysmoker

One half quart per year?

Bet the new engine goes through more than that.

firstgear

I would suggest getting a head rest and a HANS neck support device so that your neck will be ok.....

Kensmith

I have a 383 stroker 450hp 450tq and no problems. It's faster than I need but fun to just JUMP ON IT once in awhile.

davidarborg

I had a look at their website, no address, take care you're not getting scammed, I'm sure you're not, just saying.. been there

robert miller

Alot of places these days that you will know you are getting and will get what you have paid for here...

Downdraft

I wish to thank all of you for your comments, it's great to hear directly from owners. I surfed the net trying to find comments from this engine manufacturer (URE) but no luck. I do have freight and duty to consider so I am not looking for a $10,000 engine. Any suggestions for a good honest turn key 383? I don't need to win any races, its just that the stock 300 horse is somewhat "tame".

claysmoker

Ben Smeding can make you a nice 383, and he's an honest engine builder.

kwkenuf

That's a lot of money for a minor oil leak.... If 300hp is too mild for you and you have a couple of leaks, just do a cam swap, intake, carb, headers and reseal your engine with new gaskets and you'll be good to go... Beware the slippery slope however...

65 vette dude

Make that sucker a L79, or a L76, and change out that rear ratio to a 3:70...... I guarantee you will have a smile on your face when you put the pedal to the metal.

Avispa

My 427 makes 454 HP at the crank. It will spin 215/70R/15s in first gear, but that's about it. The crate motors you're looking at will be just fine. The only thing I've ever broken in this car was a clutch disk that threw out a damper spring. That was traceable to the bronze clutch pilot bushing wearing out so the clutch was rotating off center. Use a roller bearing and that will never happen to you.

Larry N. Johnson

The 65 frames are plenty strong; they came w big blocks.

We are picking up a 500 HP 565 TQ 467 CI for our 65 Convert next month if all goes well.

The stock 65 trans and rear...if traction was available...might have issues.

We are getting a Tremec 600 5-speed for the tranny.

Still worried about the rear differential.

Brakes will be fine for normal street use.

Go with a proven reliable engine builder. Take no chances.

Look like this w orange vcalve covers:

Due respect to the aftermarket builders, but how about a complete motor direct from GM? GMPP's ZZ383 should be a nice set up. If you want to do it in vintage dress (pre Vortec heads) consider a ZZ4 350.

The guys at GMPP will help you get the accessory drive and water pump right, too. They should also be able to help pick the right manifold for hood clearance. Scoggin Dickey is a big dealer for them and another info source.

just got a ZZ4 myself to put in my 62
