Opinion from some of you long time Mopar racers

I agree with roccodart. Get it on scales ASAP and then on a wheel dyno.

Then you'll have some numbers to work with. You are now (according to your numbers) 384 CID. To get 600 HP is only 1.56 HP/CID which isn't really hard to do.

You have some damn good equipment. I LOVE Norris rockers. Looks like you have a good header on it. Ignition is quality. Carb may be small...well it is. It needs a Dominator but that's not killing you. Intake manifold probably has been ported if the hands have much work on them.

The only thing I really don't like is the rear shocks. You need something double adjustable because single adjustable is useless at the level you want to run.

I think when you get it on the dyno you may be surprised to find it needs to be shifted at 7500. You didn't post your at .050 duration but I'd suspect that cam is at least 275 degrees.

Just spitballing here. Great car.

Awesome car ! The motor sounds like it has a lot good stuff in it but it’s not making the steam. Should be going 130+ at 500hp and close to 140 mph at 600. Not trying to be a smart azz but did you check if it’s getting full throttle ?

it has a 1050 Dominator. I'm going to experiment with the jetting this weekend at NED. I know it's probably jetted a bit fat based on the plug color.
I'm going to review the cam card because the guy who built the engine says valve lash should be .022 but they were set at .024 by the guy I bought the car from. Something doesn't add up there.
The W2 heads are supposed to be good. they are the race heads, not the econo heads.

The torque converter issue got confirmed last weekend. The guy I bought the car from runs the same trans and converter that I have in his current Duster. He just had his converter reworked by a shop in Conneticut ( this guy apparently use to work for Frank Lupo, but opened his own shop in Conneticut when Lupo moved to Delaware). He ran a 10.37 @ 127 at LVD this past Sunday. He was running High 10.50s prior.

I'm heading to NED this Saturday to do some test runs. I'm going to jet down the Dominator, install a different carb spacer that I got from Steve Clukey, and set my ladder bars down one hole. As for the rear shocks, like I said earlier, they're older Competition Engineering models and I can't find any info on them anywhere, not even on CEs website. So I have no idea what the do with them as far as changing any settings. They only have one knob at the bottom of each shock but there's no labeling so I don't know which direction loosens them or which direction tightens them up. Right now the knobs on each are set full counterclockwise.
