464 cid pump gas Pontiac engine on dyno makes 619 horse and 603 ft lbs of torque with Holley 2300s

Ok guys... continuing on with part 3 of our dyno session...

Here is the same 464 cid - same everything - same day, same fuel, same weather conditions, just swapped out the FiTech Go EFI 39610 Tri-power with a set of Holley 2300 series 500 cfm carbs (same port matched Trade Wind intake).

We were surprised at how stable the air was all day - we were monitoring it with a Computech pocket weather station.....

In this video you will see us warming up the engine with and without air cleaners. Just checking fitment of our 3D printed air filter bases (coming on line soon) and our 1966 FAST-AF Air Filters (available on the website now - https://www.tinindianperformance.com/product/kn-style-pontiac-tripower-air-filters/)!

Yes - good eye.... we did not have carb studs in the carbs on the dyno.... we are working on those as our new air filter bases require an offset stud to work with the stock Tri-power lids. We didn't have the studs at the time of the dyno session but we do have them now - link to site.

The dyno pull is a 300 rpm per pull and the 464 put up an AMAZING 619.5 HP @ 6000 rpm!!!! 606.3 ft lbs of TQ at 4800 rpm!!

Approximately 3 HP less than the Victor / 1050 Dominator combo!!!
That is pretty damn impressive in our book. It looks like Kauffman Racing Equipment has not only made a great high quality casting for our Pontiacs... but this Trade Wind intake seems to just flat WORK as well!

Now it is time to get busy and get this "Sleeper 464" with its new / modern Trips stuffed into our '66 GTO. Lets get ready for TRACK testing. Can't wait!
