Hey whats goin on? My names kyle, im 20 and i have a 71 challenger. i have a 318 car with a 340. im looking to upgrade to something larger but not sure what. since i never had matching #'s the sky is the limit. Im currently in the army stationed in Baghdad, saving for whatever i can get my hands on. Any advice??? Maybe 426???

 

hey i dont have any advice for you, unfortunately. But i have a 74 challenger with a 318 and i dont have matching numbers either. I was interested in getting a 426 hemi. So if anyone knows wheren to find good deals, tell me please. Also, is there anyway for me to make my challenger and r/t?

 

depending on what you want to spend, i know a great place to get a 426 hemi crate. it is www.mopartsracing.com. they have anything from 528 blocks to wedge engines and everything in between. and i was thinking of doing the r/t thing as well. what size tranny goes with a 426???

 

umm a 727 i think, but once again, not positive.

 

yeah, a 727 is what you will need, but if you are upgrading to a hemi there is a lot of other stuff you have to change as well. Make sure your rear end is at least the 8 3/4 or perferably the dana 60. you need a bigger radiator, new wiring harness, I dont know about the challenger, but the charger in 73 and 74 had different k members for the small block. If you have a 904 tranny you will need to get a shorter drive shaft I think. Depending on how much power you have, you may need to change torsion bars and I think that you have discs on the front, but if you dont you Should get it. I am in the process of replacing my 318 with a 440
