This is another test engine that I built to prove our VR-200 cylinder heads. It is a 416” (stock block) with bushed lifter bores and billet (center three) main caps using our VR-200 cylinder heads on pump gas, in a real streetcar. I personally built this engine to put on the dyno and install in a car for REAL WORLD results. This engine made pulls on the dyno as well as tested in a 100% pump gas (92/93 octane) car. The test vehicle was a 1968 barracuda street/strip combo with a flat hood and weighs in at 3315lbs (with driver) running through exhaust. It utilizes a 904 trans and 4.10 gear on a 275/ 60 tire. I believe this car has the potential to go 9.70’s with a hood scoop and a slight converter change. Just another testament to our VR-200 heads.

Thank you,
Rod

great results for a heavy car.

133 mph at 3315lbs shows 600 HP according the moroso slide ruler.

FWIW, Wallace calc is showing a little over 650hp, nice job!!! Takes some doing to set the car up for it too! Would love to see some actual dyno numbers if available.

I think the guy with this car has full exhaust all the way back and the convertor was off. It was run down in Cincinnati this past summer.
ET’s and everything line up with the blue 71 Dart that averaged 9.95 while completing drag week.
Kinda makes me want to do a roller in mine so it would run 9’s, but this offseason I am concentrating on repeatability and making the driver better instead.
New battery, new rear drum brakes, perhaps air shifter, appropriate size fuel pump and a practice tree are in the works.

What would you be going to size wise from what you have in solid flat tappet?

Same type/ size roller that Vic uses in his AMX that posts on here
268@50, 650 ish lift on a 106. The guy with the drag week 71 dart runs that cam too. I think this barracuda runs one a hair smaller duration wise.
The heads hang in there good through 650 lift..

Thanks, yeah that sounds like a good cam choice.
