dumb SS newbie questions.. Mopar

GTX JOHN · 07-31-2021, 02:18 PM

The Cuda can easily be changed to race anywhere from 70 thru 74 with
trim changes. Mike Cotton is very fast with 383 Combo and the 71 340
is also very fast (Ask my son). There are others in your body combo.
Top shelf Roller Valve train is vital as these spin up pretty high!
I would strongly recommend seeking out an Engine Builder/Machine Shop
that specializes in Mopar Stock/SS engines. I do not know what part of the
country you are located.

Thank you John. I'm going to build the engine myself. I'm a machinist by trade and own a small, engine machine shop. (small in sq.ft.) Lol. Never built a SS engine before but up for the challenge. I'll post some pics of the car and the build to all interested. I'm really leaning towards the 383 combo. Just gotta figure the right class. I'm guess the NHRA engine specs are more geared for stock eliminator engine builds. Just need to figure out what needs to be OEM within the engine and car build.

I also apologize I should have posted in the Tech forum.. Sorry guys.

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.
