dumb SS newbie questions.. Mopar

The low compression 340 in an E body has a very favorable Hp rating. Thank you Mike Loge.

Dirtmod welcome to this site. I am not a Mopar guy but I will try to start you off. To run SS in a GT class first you need to pick the engine you want to run. Use this as a reference to pick engine size and Mopar horsepower rating.

Once you pick an engine this site tell you what head casting and carburetor you must run in SS. This site will also tell you the minimum head volume CC, valve size, deck clearance/head gasket thickness, if piston is flat or domed.

You are not necessary forced to run a Mopar block. Depending on the engine you pick there could be an aftermarket block you could use. Look here to find NHRA approved parts you can use.

You are not forced to use the Mopar intake in SS. You can use an aftermarket intake.

These guys have been very helpful to me. I would identify your location as GTX John said. Local people can give you more dedicated help. I would also suggest you ask 1 or 2 questions per post so you don't overwelm people that want to help.

Thank you Ray, I'm in North Carolina. After doing some research, and the 1971 383 having a factored HP at 300hp, Looks like with my take on a novice calculation seems SS/I works? Seems like this car may be a better candidate for a regular SS class maybe not the GT. I think so far.. Lol Thanks, again.

Dirtmod I am not familiar with the SSGT stuff to advise you very well. It looks like the 383 can not be used in SS or SSGT in a 1973 Barracuda. When you go here,

None of the GT listing show the 383. Mopar and SSGT guys please chime in. Ray

One thing that's been overlooked in the conversation is since you have only a 8 point roll bar ,you are limited to to a combination that falls into SSGT/E or F ,and then only if you run the index . Even dropping to a lower class will need a cage if you run under the index.
Most viable combinations that can fit the car most likely will need a roll cage .
Before jumping into the "shark pool" ,visit a Lucas Oil Divisional race and seek out some racers that are running Mopars in SS .
Most will at least tell you what may not be a good combo and more than a few will at least steer you in the right direction.

The best bang for the buck is a 73-340 rated I believe at 242 hp. or a 74-360 rated at 265 in Superstock. You can claim either or without any trim change. Once you get into classes that have potential of running 9's you need a lot more safety equipment. ( cage, certified cage, transmission and flywheel shields. window net, grade 4 license which add to the yearly expense in some cases). I'm not a fan of a 8 3/4 if you trans brake. Specially a big block. You can run a worn out stocker small block in Superstock these days at this hp rating.

Best of luck,
