408 w2 heads 1/8mile racingarracuda

hi, just bought a 68 barracuda with 408W2 heads,W2 headers, 10,1 in comp,98pump gas, holley 830carb, mopar 557cam, bought a dynamic 9,5 street an strip converter, 4:89 rear and 727 street fighter. im gettin the engine in dyno in few weeks, does anywone has this engine?how mutch power? im going to use it to street and strip,28" tires most strip 1/8mile and want it to run 6,70. is this setup good enough?

My 408 with some mildly ported W2 heads I ported at 2850 pounds in my Duster ran 9.80’s (6.30) running 93 pump gas, 750 carb, 520 lift solid cam, 10.6 Comp, 4.88 gears, powerglide transmission, 1 7/8 headers and a 5200 stall convertor.

thanks, could be a good 1/8mile on my car, how mutch horsepower can i hope for in the dyno?

44 years of building my own engines and I never dyno’d one. The only number I care about is ET.

I'm using my Guess-Top Dyno to say somewhere between 560 and 610 hp at the flywheel. Sounds like you need a 'Glide.

R.

yes maybe need a glide, with only 2-4 races a year ihave to make sure all is good, also in the dyno.thre is no msd ignition, would it be better with crank trigger?

I built a similar(less compression) 340 with a 4.0 inch stroke crankshaft with a set of race W2 mildly ported heads and Mopar W2 intake with a custom ground solid lifter Comp Cams, that motor made 525 HP on CA pump swill back in 1994 or so
The owner put it in a 1969 Cuda fast back that ran a best of 11.0 in the 1/4 mile on the motor and 9.90s with NOS
