Turning 8,000 rpm on a 289 or 304 is not a good idea! The rods are not up to that load.
-
The first Avanti I saw with Jag IRS was in either 1972 or 1973 at the SDC meet in South Bend. I was at both but don't remember which year I saw it.
-
By the way Avanti Gray was not a very dark color and was actually a blue-gray color.

It is not the valve size that is important it is actually the flow capacity. In the dyno software if you put in flow numbers at a particular valve size and then change the valve size the program scales the flow up based on the increased valve size.
Of course the Paxton blower will never reach 14 psi. The program also looks at the temperature affects and that may be why you don't see any increase in power at 14 psi vs the 8 psi.

Valve float at 5K! Those must have been some really bad valve springs!
-
The fact that it is old will not affect how high it can rev. I wouldn't worry about going to 6500 rpm. The real problem is that at 8K rpm the big end of the rod is weak and goes oval under load. This can lead to pinching the crank and spinning a rod.
-
Don't even consider it!
Not only is load on the bolts increased because of moving the weight forward but you would have to use the transmission screw holes to mount to the stand. Because they are closer together than the bell housing holes you would use this will also increase the forces on the screws.

Andy may have said he went to 8,000 rpm on that engine but don't run any Studebaker with standard rods and the 3.625 stroke to 8,000 rpm! You may not like the results.

You have to remember that the R3 heads are not all equal. Although the drawings call for porting many or perhaps most of the engines sold by Paxton were most likely not ported. This could have resulted in a 10 to 20% increase in flow. Based on flow for an unported R3 head with the R3 cam 330 hp is about right. A ported R3 head with R3 cam would be close to 400 hp.
So was Brad's engine with ported heads or not and which "R3" cam did it have?

Dave Bloomberg has owned his 1963 Avanti since 1963 and that is 52 years.

The answer is quite easy and doesn't require counting. The answer is the same as a non R engine and the same as all the other R engines.
-
I believe it is true but it has been a while since I have looked at these.
-
Oh well the 6 cylinder car didn't go fast enough for those to have much impact!
-
No, a red Super Lark!
-
This is most likely and should have been true as the Halibrand wheels would have created more drag.
-
False, they are the same. The Hawk and Lark R1/R2 dampers are also the same except they have a belt groove cut into them.
-
The chrome rims are bezels. The inner part is not a bezel.
-
It should be pointed out that the as designed rod was for a pressed in pin like the SBC. Some rods were modified by Paxton to use a bushing for a full floating pin.
-
They are more or less standard size. The bearings that Studebaker used are the same as, for example, some Chevy's and Fords. Therefore the bore in the hub is the same and therefore the caps will fit. You may find that the replacement caps are a little tighter than your old Studebaker dust caps.
-
To call it a roll bar is being a little generous but without it the roof would have no strength.
-
lower pulley also balanced.
-
But, I doubt more than two cars utilized them.
There were more than two but not many. Those changes were made to increase the camber gain while cornering and lower the front a little with standard spring height.

However I have seen some aftermarket 14" wheels on an Avanti.
Koni Shocks For Studebaker and later Avanti's
in Avanti Pub
Posted
I am working on obtaining Koni shocks for Avanti's and other Studebakers. These will fit not almost fit, such as the Camero shocks that some have used. If you are interested please post your interest.
