I have the 452;s on my 63 Polara 440 with a 750 dp on a RPM, CNC Stealths, Isky 292-242@50 108LSA. Flat tops with .039 gasket. 3000 stall and 2.94 gears. So yes it’s not a beast with these gears. But hit the pedal hard and 1st is a smoke show. Great fit with p/s.

What balancer and timing mark are you using. Could the balancer ring have slipped on the hub?

76 440 out of a motorhome. Cast crank. Speed Pro 2355 030. Clevite rod and mains. Billet t chain set. Stock 452 heads all fresh. Comp 224@050 cam. Rpm with a 600 eddy carb. It was a basic rebuild with good parts. Now it’s cnc stealths, Isky 292 mega cam, full msd system headers and a 750 DP...

The PO didn’t remember what bolts his builder used. All I have is this one picture when my guy checked some bearings and confirmed it was balanced. This is an older build. Maybe 8 to 10 years ago. It spins 5500 easily and is smooth as glass. Thanks guys. Bob.

Your car is so very Bad Azz..

ATI;s were at the top of our list of preferred dampers.

Mine turns 3000@80 mph. 28 tall tires.

I am thinking I should look into all that’s necessary to switch axles to non press ones.

Might be some duplications. I ran 3.55,3.73, and 4.56 in GM rears. Some commonalities might exist.

3.73s might be a good chioce

Even though a 6/71 or 8/71 pulse load the blower belt, the belt does act as a torsional damper. When I worked at Scat Cranks we would deep drill the damper bolt hole all the way into the front main. But not into the oil passage. Then using a long stud torque a hub in place. That puts the entire...

Can’t be quick enough. Have my kids house and ours up for sale. Family in Marion. That’s the target area.

There’s another color? I bleed red, my cars red and my guns “if I had any” vote red.

I have a small pinion carrier. Buying a good used one with a posi or a locker would be a good choice. I am going to need to do axles too. Mine are the tapered ones. I am fleeing the commie state of CA and headed for the hills of NC. I have lots of family there. Looking at some properties with...

Mostly cruise night stuff and drags. Just never heard of 2.93s before.

So I just got my tach working. 80mph at 3000rpm with 28 tall tires. Converter flashes to 2800 in 3rd. Figure a 6% slip. Figures closest to a 2.93. It was a factory 318 auto. No wonder it’s a freeway flyer. Since I have a small pinion carrier I will upgrade to a large pinion with a posi or...

sorry 10 degree locks

I'm on my first RB motor but every Chevy V8 I have ever done is that way. Dot to dot is tdc #6

I still want to dyno it and do some jetting and timing under load. But i'm pretty satisfied so far.

I can tell you that mine with 7cc valve relief, .017 down the hole, .039 felpro 80cc Stealth CNC heads, Isky 292 mega cam [email protected] and a holly 750. I can run great on 12 deg initial and 24 more centrifuAl on 91. If I wanna lead foot it I take 2 degrees out. Otherwise it has a very light ping...
