LT1 rocker arm question

[AI#97]

Because the stock stuff works fine. Roller rockers are an added expense. If we had guys all across the country galling rockers and nobody could get them to hold an adjustment that would be different.

Hmmm, are ferds allowed to have them? What about longtubes on an LT1?

Another no. Factory manifolds only. Still restricting from there anyway...

The 5.slows can as the Cobras came with them stock, but they need to be the factory correct type. Only stock manifolds need apply for the LT1. There's no point in opening that up as they need to be restricted anyway.

If only there was a place you could go to get all these answers yourself...

Cory's car (previous Matt's) never raced in legal CMC trim so the long tubes were never an issue. It obviously would need to be converted prior to racing for points/contingency.
Any quasi-legal car can "fun run" just to shake down while the driver gets the non-compliant issues sorted.

We fixed that issue...that car got cut up and parted out. It will never offend anyone again.

It never offended anyone. IIRC it only ran one event as a fun-run many years ago prior to Cory owning it.

I keep restricting and lowering hp but torque stays North of 317.59avg. Soon will be in the 240's and have illegal torque so looking for other ways to get hp... But kill torque. Short of cutting a custom cam.... Lol!

We did bump the start RPM for Dyno pulls to 2500 in case that peak number is right at 2000 when you crack the gas.
