Re: Question About Sleeving A Block

As mentioned a torque plate would have to be made since most of them are a little over the largest commonly available overbore. The idea of pre-stressing the block while sleeving is good but little impractical. I have issues with boring and sleeving all the cylinders. The mains receive much of their...

Re: Superflow parts

Last I knew Superflow, at least the dyno part, was now part of Powertest. I know nothing of their support of previous models of Superflow but they still have parts and service for past models of Stuska brakes. Might be worth a call. 262-252-4301

Re: 383 with Weiand 177

Guess it don't make any difference since you are returning the blower. Concerning the register being too big on the lower pulley, does it fit a BBC damper?

Re: What tires for a dually?

I'm still puzzled by a couple of things.

What were 4 ply tires doing on a dually? Thats a car tire!

Why buy a dually if you are concerned about ride?

Agree with letting the pressure down. Try about 50psi until you load it.

Re: Cracked Head: It’s Complicated

I want to offer a word of advise. Since the head has been braised on, you need to get all the brass out or else you will have nothing but trouble laying in the iron.

Re: Timing belt to MSD dist. brkt. clearance

Providing the distributor belt is tensioned correctly, guess the "fix" might be to machine the bracket for clearance. Kinda sucks cutting on an anodized bracket but it is in a place that don't show. :D

Re: Timing belt to MSD dist. brkt. clearance

Since no one has answered your question, I'll try and ask a couple. Not on the .391 raised cam but standard location block there is around 1/4" clearance. Wonder if the RC Jesel has bigger sprockets? What is the tooth count?

Re: 2023 Corvette Z06 LT6 engine

The difference with that damper is the factory engineers would have properly designed the damper, know the crank frequencies and driving orders. Probably the driving order criticality would change with the flat crank firing order, and probably the critical frequencies are higher. Pretty likely this...

Re: 2023 Corvette Z06 LT6 engine

Hear lots of people stating viscous dampers have no place on performance engines and will cause the crank to break. Noticed there is one on the LT6. Interesting since flat plane V-8s have issues with balance and vibration.

Still trying to figure the reason for the three stacked coils at TOP of the valve springs.

Re: Cam Spec.’s for GM’s new 1000 HP pump gas engine

SupStk, about your reply on the Heads on the New GM 632 C. I. , did some math. Assuming the pistons are flat tops w/ two valve notches and they are down .025" below deck, an 85 cc Chamber would put it at 12.07. Some cylinder heads would require dished pistons obviously . Mark H. I read the previous...

Re: Cam Spec.’s for GM’s new 1000 HP pump gas engine

This thread has gotten sideways.

Back to the original post, those heads still has my curiosity up. From the height over the standard intake ports, what do y'all suppose? 18 degree and 70 cc chambers? Might be a game changer for BBC builds.

Thanks for the history of the Novi. Heard of it but knew nothing of the history and the problems encountered.

Curious about the port layout and chamber configuration.

I'm curious too! Googled the part number 19431810 and got the same info previously posted.

Re: electric water pump problem

Just something to check, some pumps have a rubber plug on the front of the motor. Under the plug, the armature shaft has a hex that will accept an Allen wrench. If your Summit pump has that feature, give the armature a spin and it will probably want to run.
