-70-74 Challenger and Cuda Subframe - Speedtech Performance USA

perfect.. thanks again.

just a bump.. has anyone used or know of anyone that has put the speedtech front end on. It appears its a full front stub. alot of work, but seems like quite a robust setup.

Thanks scar426. I'll give chris a call. anyone else with things to think about.. or issue you have run into that would help me?

what about a throttle? if i go with a hell cat i assume i have to run a throttle by wire? Is that something that can be purchased after market, or do i need to find a charger / challenger hell cat pedal?

Hi everyone. I have been driving and running track days with my heavily modified 70 challenger. Currently it has a big block and a Tremec 5 speed, but the engine is hurt. I'm giving serious consideration into a Speedtech front stub with coil overs and a hell cat crate engine. Can anyone give...

Thank you Chryco Psycho. to confirm, new hemi bellhousing bolt pattern is same as LA/Magnum?

Has anyone used the Speedtech front stub? It looks very robust!! I'm considering one, would love to hear if anyone has done it?

has anyone put the Speedtech front stub on their E body? The system looks very robust!

thanks guys. I assume a new CPU could handle that i want to run a manual and would be able to eliminate things like traction control etc....

some searching around i've found hotwire...? I know for a while mopar was a "locked" ECU.. Do those places have a full start from scratch harness with computers and have tunability? I will be using a 6 speed , no other electronics needed..

Guys / Gals, I'm sure there are a million posts and threads on this. Any help you can provide is appreciated. I have an opportunity to purchase a 2019 Hellcat engine and auto transmission for very cheap. no PCM and i would definitely acquire a 6 speed instead of the auto. The car is already...

I think I"m going to try and do the sam posey fender flare route. just round out the top.. I hate to change the beautiful lines of the car. Then the next question.. I don't need fender flares out back, as I tubbed and narrowed things. But should I flare the rear so it matches the front.

Yes I had the hood built... and finished it myself. I found a fiberglass company out of ontario canada that said they could put any scoop on any hood. they roughed it in, I finished it. I love the AAR Cuda hood, but no one makes it for a challenger.

Ya. I've been studying the sam posey car.. its not a bad idea. That car doesn't look like flares so much as the fender was "bubbled" out.

I'm transforming my 70 challenger into more track car. I know I can 245s up front. Based on some basic measurements, I THINK... I could get 275s up front with rolled lips and right back-spacing. I would like to get front tires closer to 295 or 305 so the car will really turn. Has anyone...

500 cube big block in a 70 challenger... Probably would have been fine if I wasn't using slicks.

Who is building tough 8 3/4 rearends and what components in them? I just blew up my 8 3/4 this weekend at the drag strip. Ring/pinion is gone and it tore the caps off the centersection as well. I want to stick with the 8 3/4, but I need to build one much stronger. Any ideas on which...

I blew up my 489 series 8 3/4 this weekend at the drag strip in Union Grove. The ring/Pinion broke and took out the caps on the center section. or vise / versa, not sure what happened first. I trying to build a strong replacement. Anyone have a legitimate opinion on the 742 cases vs the 489...
