There all gonna give you similar performance. The reason I picked comp xr274hr is cause your running a bit heavier of a car. Youll would have to watch the compression on that one.
Rumbles cam is basically the 110 version of the thumper. But still will have a very healthy Idle.
The thumper will sound lile a top fuel car :)
You really can't go wrong. Especially with 4.10 out back.
Thanks for your help! The Coronets shipping weight was 3285 with a slant so about 3400lbs with a 360 is my guess. Currently has its numbers 318 still chugging along. What stall would be good with the thumpr or its 110 LSA cousin in your opinion?
I love this forum and how everyone helps out. I'm glad such a resource is easily accessible.
