Re: need to pull engine

When you buy an engine "leveler" or "tipper", buy the good kind with the screw and handle. Don't get the cheapo kind with the cables that works by inserting a ratchet handle.

This is an "el cheapo" one from Harbour Freight. There is a fine thread drive scew attached to the handle. It's pulled a lot of engines and it works great.

If you are in a real hurry, here is a link to a video on a quick engine removal.

Re: need to pull engine

And what does this do to the overall charastics & function of the engine? Thanks

See the Fall 2010 Corvette Restorer "...Tale of Two Camshafts" article for all the configuration details, operating characteristics, and performance tests.

I'm still looking for a 327/300 owner to install a McCagh Special camshaft along with the head work and other recommended internal changes - either with a manual transmission or Powerglide. Given the near same displacement, but shorter stroke, a 327 should make nearly as much torque as Mike's engine with a simliarly flat curve, but the actual peak will be a few hundred revs higher.

Likewise, given the better flowing 327 heads, the configuration should make more top end power at higher revs with the top of the useable rev range somewhere between 6000 and 6500.

Mike's engine proved that the McCagh Special camshaft can pass a PV in any engine that originally had the base hydraulic lifter camshaft - 3733431 from '57 to '66 and 3896929 from '67 to '80.

If you're interested, shoot me an email.

I've used the $24 leveler to pull the body- worked like a champ!

Re: need to pull engine

Duke,

I'm ALWAYS reluctant to ask a DUMB question.................but......at the risk of another! This has been bothering me for some time so I might just as well go ahead and take the leap. On this engine with the special camshaft and way more than the original advertised 300 hp (which passes PV) how is it possible to continue to use the 300 hp harmonic balancer while turning 1000 more revs? How does the 300 hp harmonic balancer do the job of the visibly much larger factory SHP balancer? Obviously, to me, that doesn't seem like a dumb question..........but. Thanks.

Re: need to pull engine

That's an excellent question!

If the 300 HP crank was cast iron I could probably get away with saying that since cast iron has more inherent damping than steel, it's okay, but the 300 HP crank is forged steel, like the SHP cranks. The only differences with the SHP cranks are nitriding, which doesn't have an effect on the crank's torsional characteristics, and mass since the SHP crank is a little heavier due to additional balance mass for the heavier SHP pistons, and this may have some effect.

Chevrolet has always had a durability qualification test prior to releasing an engine for production. Typically it involves cycling the engine under load from the torque to power peak - or the redline. Back then it was probably no more than 200 hours. Today, it's at least 400.

So I expect they must have found that the crank had a torsional resonance above 5500, which dictated a more robust torsional damper.

A lot of medium performance 327s have been hotrodded over the years (same applies to base 350s) to turn more than the OE redline, and I don't recall ever hearing of any that suffered any crankshaft ills, so the very small time that a Special 300 HP engine will spend in the 6000-up range in typical vintage car service likely won't do any harm. At the same time, I wouldn't recommend that someone run a Special 300 HP engine with 6000+ rev shift points in the 24 hours of LeMans unless it had a SHP crank with the big damper.

It's too bad that Chevrolet didn't discover the weakness in the early rods during the durability qualification testing. That cost a lot of engines in the early to mid sixties.

P. S. The only "dumb" questions are the ones that have been asked and answered six times a year for the last 10+ years.
